Growing into tomorrow
Over the years I’ve spent countless hours reading, learning and speculating about the future of humanity and the planet we call earth. In my first years of college in 1988-1990 I first started learning about the human rights movement, alternative agriculture, and the budding american Green movement. I founded a Green local in my college town, Kirksville, MO and I began to identify myself as an activist. Between my time away from family as well as this fundamental shift in my identity I began to notice a crack which became a gulf in how I related to my fellow humans and they to me.
Looking back I’ve come to realize that the “activist” is actually a strange phenomena. In a participatory democracy, there would not be a need for “activists” which are really just citizens which are involved in the community process of self-government. In a participatory democracy all citizens are active. The republic that we have today is, of course, a far, far cry from a real democracy. To suggest that it is democratic is to twist and pervert the word to such a degree that it no longer resembles its original meaning. (It was never a participatory democracy at all, but a republic that was supposedly controlled by citizens via representatives via “democratic” elections. But really, the differences, while important, are another topic for another time.)
Over the years (most notably beginning after WWII and the rise of suburbia) the people of United States have been taught that life is about the American Dream. It is about being happy which comes with certain material possessions as well as a neatly defined nuclear family of husband, wife, and kids. Of course the American Dream is open-ended and the list of material possessions grows and grows and is never completed. In accepting the American Dream as our way of life we gave up citizenship and became consumers who were no longer concerned with the serious responsibilities of being involved in government. In allowing ourselves be redefined we gave up power to those who did the redefining: the wealthy upper-class which controlled corporate capitalism and the state.
The role of “activist” came about because there are still citizens that strive to be actively engaged. I’ve come to realize that the disdain and outright hostility that I’ve faced as an activist is a fairly common experience and is related, at least in part, to the psychological and life investments made by the majority of people in the U.S. People went along for the ride. They were offered a way of life and they took it. They may not have even realized what was happening. My parents are a good example. They were a product of their socialization and they accepted what was put before them as the normal way of life. The development of suburbia and a shift to consumerism were the next steps to be taken after the Great Depression and the emergence of the U.S. as a world power after WWII. My parents got their jobs, bought their car and home then started having children. They moved, kept their jobs, bought another car and continued to raise their kids. They invested their lifetimes in this way of life. They believed in this way of life. My two siblings followed suit with their own families, jobs, homes, cars, pools and kids.
Imagine the emotional response of having that way of life criticized. By definition an activist (active citizen) is critical and vocal. The role of the citizen is to strive towards informed and ethical decision making for the community good. It is an unfortunate fact that to be an active citizen in our society often leads to separation from the majority in thought and behavior in part because we are often considered to be “judgmental” which, of course, we are. We do “judge” in the sense that we form opinions and conclusions regarding the everyday life around us. Being an active citizen is a never ending process of responsibility which leaves no stone unturned. It means looking at how we get things done: transport, growing of food, production of material goods, etc. and making determinations of how those actions and systems are working or not working.
In the 20 or so years that I’ve considered myself an active citizen I have consistently been met with resistance. Most people are not open to the idea that their way of life requires the suffering of others. It’s not comfortable or convenient because it implies a sense of guilt about both the system and the people who are a part of it. If a way of life is implicitly unfair and unsustainable and we willingly participate in it what does that say about us?
With the arrival of peak oil, climate change, and serious economic crisis all at the same time, many people are seeing the cracks in the way of life that they have taken as a given. As the cracks begin to expand and the system crumbles the whole gamut of emotional and mental states will run its course through the “consumers” of this nation. I suspect that anger, fear and confusion will dominate. The process is already well under way and if we’re lucky it will continue to unwind slowly. If that is the case then perhaps panic and violence will give way to community-based movements of cooperation. I don’t hold out much hope for this. The shift in our way of life is going to be monumental. Every aspect of how we live is about to change as the cultural, political and ecological repercussions of the past 60+ years step onto the stage. Perhaps the two most significant differences between the Great Depression of the last century and this “Long Emergency” (as James Kunstler refers to it) are the planet’s population of 6.5 billion people and dwindling fossil fuel resources.
Eleutheros of the excellent blog How Many Miles from Babylon describes it as a
shift in paradigm :
Facing the realities of our immediate future calls for a shift in the paradigm, a shift in thinking, a shift in the mindset.
–
We are mentally conditioned to think that we would be happier, more comfortable, in a larger over heated and over cooled house. We think prepackaged food is vastly easier to prepare. We think a food processor is a hundred times easier than a knife. Of course this farmstead is on the lunatic fringe. We have experimented with cutting all the firewood we need for heating and cooling with hand tools. It’s some more work, to be sure, but not much. Yet in the imagination of the uninitiated, a chainsaw is many hundreds of times less work.
On this farmstead 85% of our food involves zero food-miles and almost all the rest is bought bulk, we use very little electricity and no commercial gas or other fuels. We wear used clothing. We drive bottom feeder vehicles and those only very rarely. Yet how much do we impact global energy and resource use? None, negligible at any rate. The random motion of molecules accounts for more fuel savings that we do in the scheme of things. What we represent is not some quantified amount of energy and resources saved, but rather a complete paradigm shift from the consumerist world.
I’ve said many times before that I think it is far too late to stop what is coming. It is a done deal. The question is how will we handle ourselves as this amazing shift in our way of life occurs. Will we rise to the occasion? Will we learn and share the skills necessary for survival? Will we step out of our air-conditioned lives and do the work that is now required? Billions of people on planet earth deal directly with survival issues every single day. They know hunger, thirst, extreme cold and heat… for them, survival is not a reality television show but a fact of everyday life.
When fossil fuel based agriculture fails and the shelves remain empty will we eat the drywall of our over-sized homes or will we learn to grow and preserve food the way our ancestors did? I wonder how many people have a basic understanding of how to garden and preserve food? How many have actually tried it and thus have an awareness of how much can actually be grown on any given amount of land or how much time is required? What about growing from seeds and saving seeds for the next season? Will they have access to gasoline and a tiller to prepare the soil or will they double dig by hand or sheet mulch with cardboard? Do they know about squash bugs or japanese beetles? What will they do about water during times of drought? Will a nation of people used to consuming fast food and microwaveable box dinners even know what to do with the vegetables that they’ve grown? How long will it take them to learn to enjoy real, whole and healthy food?
As individual people we have a lot of growing to do. As individuals that inhabit rural roads or streets in towns and cities, we’ll need to develop better relationships with neighbors which can then be grown into communities.

Improvised shade for energy conservation
I had another one of those aha!! moments that is almost embarrasing because it was so long coming. As I’ve written recently I’m not using air conditioning as a part of my effort to reduce my personal impact on the climate. I’m also living in a cabin which is not completely finished on the inside. The ceiling is finished and well insulated with a ceiling fan installed. I’ve still got two walls that need the electrical wiring finished, insulation on two walls still to be installed and then pine bead board for all of the inside walls.
Much of my cabin is shaded at various times of day but it does get hit with a good bit of direct sun. About half of the east facing side gets full sun from about 9am to noon. I made it a point to insulate about half of this wall a few weeks back but a good bit of heat still makes it through. I would have done the whole wall but I have a good bit of temporary shelving nailed up to the other half and it is fully stocked with food so I stopped at the half way point.
Three weeks ago Greg brought down a truck load of used 2x4, 2x6, and 2x8 wood to be re-used for a variety of future projects. We stacked it into a neat pile where it has been sitting ever since. Meanwhile I’ve been working, observing and thinking about the design elements of the site and future projects. I decided very early on that I’d be putting a series of eight or so raised rain collection barrels along the back/east side of the cabin and that I’d put a lattice or similar structure on it for some sort of perennial fruit vine or an annual bean/squash vine to provide food and shade. I may also plant a couple fruit trees back there. But those projects won’t be completed until early spring of next year.
Now, for that aha! moment. It’s hot and humid outside. I’m hot. My dog is hot. My unfinished walls are getting direct sunlight and heating up outside and inside. Why not lean all those neatly stacked boards up against the east side of my cabin? So simple and obvious!! In ten minutes I’ve provided a solid wall of deep shade that should easily give me another hour or two of inside coolness. I’ll be doing the same thing along the south side of the cabin which gets direct sun from about 3pm to 5pm.
Greg will be back down around the third weekend of August and we’ll get the inside walls finished off but I’ll be leaving those boards up until they no longer get the direct sun or until outside temperatures cool down, probably the middle of September.
It always amazes me how many people do not shade their houses with trees, bushes or vines. I suppose that the combination of cheap energy, air conditioning and fairly well insulated homes combined make it easy for folks to ignore or not realize just how much direct sunlight on exterior walls can heat a home. As energy becomes increasingly expensive and eventually as shortages occur I expect these details will become more important to more people.

Living without an air conditioner and the end of the world
I wrote the other day about not using a refrigerator as a part of my efforts to reduce my carbon footprint. I’d mentioned that if we in the U.S. are going to lower our our carbon footprint to a level which is equitable and closer to sustainable that we would need to lower our emissions by about 90%. Ninety. Percent. That is a drastic reduction. Ponder it for a moment. Hell, ponder it for the rest of the day if you’d like.
I came across that particular percentage will reading through this post by DJ at the excellent blog, Asymptotic Life:
Listening to Radio West yesterday, I heard a guest make an interesting point: if we tell poor people around the globe that they can’t live the way we do, we’re trying to prevent global warming by forcing people to continue to live in poverty. That is, for most of us, morally unacceptable.
Our current attitude seems to be that we can afford to buy all that energy and emit that CO2, and “they” can’t. Too bad, but bully for us…
—
What would it look like to create an equitable and sustainable per-capita CO2 emissions policy? Assuming everyone emitted the same amount of CO2, how much could we all emit without frying the planet (and all of us with it)?
Let’s assume that, to keep CO2 concentrations low enough to avoid catastrophe, we limit CO2 concentration to 350 ppm— down from today’s 385 ppm. That means cutting CO2 emissions by 50% of their current levels. At 2004 levels, the world generated 27 billion metric tons of CO2— more than 20% of that by the U.S. alone. That means we’d need to reduce to about 13.5 million metric tons worldwide.
The world population is currently 6.8 billion people. That means each person would be allowed to emit 2 tons of CO2 per year. For 88 countries in the world, that’s a step up— more than they currently produce per capita. But for we priviledged few in the U.S., that means cutting our per capita emissions (currently over 20 tons per person per year) by 90%.
One of the largest energy hogs in any household is the air conditioner. Others at the top of the list are whole house forced air heating systems, hot water heaters, refrigerators, freezers, and plasma tvs. In addition to not having a refrigerator I’ve decided I will not use an A/C. I do have a small window A/C but only run it at the request of visiting guests. When it is just me and Talula we get hot, damn hot. We cool off with lots of water, we slow down and sit in the shade. We’ll survive just like many of other billions of humans who survive everyday in hot climates with no A/C. It’s not easy, not fun (well, actually swimming is fun), not comfortable but it is possible.
Before I move on let me quote another of DJ’s excellent posts, What Two Tons Means to Me:
Last week, I calculated that a sustainable and equitable rate of CO2 emissions would be about 2 tons per person per year. Currently, the U.S. emits just over 20 tons of CO2 per person annually. Of this, according to EPA, 20% (4 tons) is caused by household energy use and about 27% (5.5 tons) is caused by four-wheeled passenger vehicles. The remainder, about 11 tons, is generated by the economy on our behalf, including manufacturing, agriculture, cement and steel production, and transportation of goods both for us and for export.
Let’s assume that DJ’s figures are correct. Even with my limited use of electricity I am averaging 25 Kwh a week, about 100 a month. That’s for one person in a small cabin of 192 square feet. On a typical day I use: 1 compact fluorescent light, a ceiling fan, a window fan, and a laptop computer. Other appliances that draw power on occasion: water well pump, battery charger, external hard drive, computer speakers, and phone charger. That’s it and it still adds up to 100 Kwh a month. The average U.S. household uses just under 900 Kwh a month, just in electricity. Imagine the difficulty of cutting that by 60-80%!
Want to try something interesting? Take a weekend and power down everything in your house. Go through room by room and unplug everything on Friday evening. Over dinner discuss the adventure and what it means. Experience Friday night and Saturday without power. Use the time to discuss and evaluate your needs. Define the difference between needs and wants, needs and comforts. Make an effort to understand your needs and usage as they relate to the needs and usage of the vast majority of families around the planet that use far less. Sunday morning or afternoon begin the process of slowly and thoughtfully plugging things back in based Saturday’s discussion.
Remember, we’re not even considering the carbon that is emitted by personal transportation, emissions that would need to be cut by 80% or more. Then there are carbon emissions related to consumption of food and consumer goods.
This is why the governmental “solutions” put forth by congress and presidents (or the current crop of presidential candidates) are a sad joke. These folks are not even CLOSE to realistic. The same goes for the myriad “100 things you can do to save the planet lists” that we see put forth by media and mainstream environmental groups. Sure, we should all do the easy things that are on those lists but the reality is that if we are serious about slowing climate change we are going to have to make drastic changes to the way we live. I’m all for it, I think we absolutely should go all out. I think we should sacrifice, should do whatever it takes. But my guess is that most folks would laugh at the idea. Frankly, I don’t think that today’s Americans have the strength of character the task requires. We’ve been far too spoiled for far too long.
When it comes down to it most folks in western “civilized” nations will only change when it is forced on them when resources are no longer available at prices they can afford. We’re already seeing that people are driving less in the U.S. now that gas is averaging $4/gallon, imagine gas at $6, $7, or $8 a gallon. Imagine utility rates doubling or tripling. Those things are coming sooner than later and I for one welcome them. Yes, they will bring hardship and suffering and around the world billions are already suffering as they are already effected by price increases. Regardless of what reality is about to force upon us, it is probably too late in terms of the climate. What we have set in motion will not be easily undone, most likely we will hardly slow the process at all.
Michael Stipe said it best: It’s the end of the world as we know it.

The great eggsperiment
I’ve mentioned before that a part of our plan here is to have chickens which are, of course, an essential ingredient in almost any permaculture design. Not only do they provide eggs and meat (not for me!), but also manure, warmth for plants in an attached greenhouse, feathers, and they help weed/till the garden as they eat insects and food wastes. In short, chickens rock. I cannot wait to get our coop built and the chickens moved in. For now I’ll content myself with eggs which are raised by someone else in their backyard. What’s great about home raised eggs is that I can request that they not be washed. You may not know this but eggs have a protective layer which keeps them perfectly edible for up to three weeks without being refrigerated. Neat, eh? This is especially important for me because I do not have, or plan to get, a refrigerator. Let me explain.
One of the primary principles of permaculture is earth care which means, in part, reducing our carbon footprint. For those of us in the U.S. this means a drastic reduction of about 90% (I’ll discuss that figure in another entry to be posted soon) if we are to have an equal share with the rest of our fellow humans. In addition to earth care there is of course the added reality of peak oil/coal/energy (peak everything really but that’s also another post for another day!).
What this means for me in my day-to-day life is that I have made a choice to not have the typical electrical appliances that most people in the U.S. take for granted as necessary for life. This brings me back to the refrigerator. Because I don’t a refrigerator I have to adapt, I have to think differently about how I use and store food. I have to make sure that the eggs I get have not been washed so that I can keep them at everyday temperatures. I no longer drink soy milk which I only really used as a creamer for coffee. Also, no cheese which I don’t miss much since I rarely ate it. It means that I have to be careful when I cook so that I’m not cooking too much. If I do have left overs I can usually keep them in a small cooler with a bit of very cold well water and eat them the next day with no ill effects.
I’ve been living without a refrigerator for nearly two months and I’m still very healthy. It has required a few modifications to my diet but nothing drastic. It’s just one step towards a smaller carbon footprint and a way of life that will likely be a fact for most of us in a future with fewer fossil fuel resources.

A Busy Week!!
It’s been a very busy week since my last post! In anticipation that I might be adding to the orchard over the weekend I spent last Friday creating paths through the brush and grass. My sister and brother-in-law visited with their kids for the weekend and she stayed with the kids for another couple of days. On Saturday Greg got the electrical work in the cabin finished and on Sunday the two of us put in the ceiling (insulation, tongue and groove pine boards, and a ceiling fan). They also brought down another 10 fruit trees for the orchard which makes a total of 17 trees! On Monday I put in three Golden Delicious apple trees and since Mondays are my set day to water the fruit trees I also hauled up four buckets of lake water for those that are already planted. I got three buckets from the rain barrel which is nice since it is so much closer. On Tuesday I put in the last Golden Delicious and cleared more paths as well as put up insulation on one of the walls in the cabin. On Wednesday I put up more insulation and planted a peach tree. Today I put in another two peach trees, so, seven planted and three more to go. I should have the remaining trees put in this evening or tomorrow.

Rain Barrel Nerd
You know you are a total nerd when the highlight of your day is a brief rainstorm that fills your rain barrel half way. With the new (actually 20+ years old and re-used) gutter all the rain is now directed to the barrel and our five minutes of heavy rain just now filled it to half. Sweet. I can’t wait to get the others and hook them up into a proper series. I’d like to put in 10 but I may only be able to fit 8 or 9 which would still be a nice bit of water to have around. Given that this barrel would have filled in just 10 minutes I’d estimate that 8 barrels will easily fill in less than two hours with a fairly hard rain, much less if the rain were as heavy as what we just had. Maybe I need 20 barrels?
My expectations of a future shaped by climate change and peak energy is that we must become very efficient at harvesting and using/conserving fresh water. It seems to me that we can expect increasingly erratic weather with periods of extreme drought and wet far beyond what we’ve seen in the past. Combine that with the myriad issues related to agriculture and peak energy and you have lots of trouble in regards to a steady food supply.
If I can harvest and store 1650 gallons of water for use during drought then I will… guess I need 30 barrels!
An ice-free Arctic in just 23 years?
Big fucking surprise. Or not. Look… how many times do we have to see these words over and over? “Sooner than expected”, “much worse than previously thought”. I’ve said it before, this is happening at a pace far faster than even the worst predictions. We have got to start thinking of climate change as RIGHT FUCKING NOW. This is NOW. This is not 100 years from now. This is not great grand children or the next generation. FUCK. Stop eating meat. Stop driving. Stop consuming. FUCKING STOP.
I hate humanity and truthfully, I think I’m starting to take pleasure in seeing people suffer from weather related catastrophes. If only that suffering were more focused on the U.S. and other primary contributors of atmospheric carbon. It’s harsh I know but FUCK. How stupid, shortsighted and selfish can we be?

Jeff Masters over at Wunderground discusses the issue:
None of our computer climate models predicted that such a huge loss in Arctic ice would occur so soon. Up until this year, the prevailing view among climate scientists was that an ice-free Arctic ocean would occur in the 2070-2100 time frame. The official word on climate change, the February 2007 report from the U.N.-sponsored Intergovernmental Panel on Climate Change (IPCC), warned that without drastic changes in greenhouse gas emissions, Arctic sea ice will “almost entirely” disappear by the end of the century. This projection is now being radically revised. Earlier this year, I blogged about a new study that predicted abrupt losses of Arctic sea ice were possible as early as 2015, and that we could see an ice-free Arctic Ocean as early as 2040. Well, the Arctic Ocean has suffered one of the abrupt losses this study warned about–eight years earlier than this most radical study suggested. It is highly probable that a complete loss of summer Arctic sea ice will occur far earlier than any scientist or computer model predicted. In an interview published yesterday in The Guardian Dr. Mark Serreze, and Arctic ice expert with the National Snow and Ice Data Center, said: “If you asked me a couple of years ago when the Arctic could lose all of its ice, then I would have said 2100, or 2070 maybe. But now I think that 2030 is a reasonable estimate. It seems that the Arctic is going to be a very different place within our lifetimes, and certainly within our children’s lifetimes.” While natural fluctuations in wind and ocean circulation are partly to blame for this loss of sea ice, human-caused global warming is primarily to blame. In the words of Dr. Serreze: “The rules are starting to change and what’s changing the rules is the input of greenhouse gases. This year puts the exclamation mark on a series of record lows that tell us something is happening."
The implications
The melting of the Arctic sea ice will not raise ocean levels appreciably, since the ice is made up of frozen sea water that is floating in the ocean. Sea ice melt does contribute slightly to sea level rise, since the fresh melt water is less dense than the salty ocean water it displaces. According to Robert Grumbine’s sea level FAQ, if all the world’s sea ice melted, it would contribute to about 4 millimeters of global sea level rise. This is a tiny figure compared to the 20 feet of sea level rise locked up in the ice of the Greenland ice sheet, which is on land.
The biggest concern about Arctic sea ice loss is the warmer average temperatures it will bring to the Arctic in coming years. Instead of white, reflective ice, we will now have dark, sunlight-absorbing water at the pole, leading to a large increase in average temperature. Warmer temperatures will accelerate the melting of the Greenland ice sheet, which holds enough water to raise sea level 20 feet. The official word on climate, the 2007 IPCC report, predicted only a 0.6-1.9 foot sea level rise by 2100, due to melting of the Greenland ice sheet and other factors. I believe these estimates will need to be revised sharply upwards in light of the unexpectedly high Arctic sea ice loss this summer.
One more point–global warming skeptics often criticize using computer model climate predictions as a basis for policy decisions. These models are too uncertain, they say. Well, the uncertainty goes both way–sometimes the models will underestimate climate change. We should have learned this lesson when the ozone hole opened up–another case where the models failed to predict a major climate change. The atmosphere is not the well-behaved, predictable entity the models try to approximate it as. The atmosphere is wild, chaotic, incredibly complex, and prone to sudden unexpected shifts. By pumping large amounts of greenhouse gases into the air, we have destabilized the climate and pushed the atmosphere into a new state it has never been in before. We can expect many more surprises that the models will not predict. Some of these may be pleasant surprises, but I am expecting mostly nasty surprises.
Al Gore's climate change hypocrisy

You know, he’s got plenty of critics and with pictures like this it is as though he wants to give them more to critique. Damn Al, I mean… Really?? Do you need three 30” lcds? Do you? Three? NEED them? Al, let me keep this simple: you’re being a dick and you’re certainly not helping the cause. The problem of climate change requires that we humans change the way we live, particularly the way we use resources. I look at this picture, just one little part of Al’s life, and I see someone using more than his share. Period.

Climate Change Round-up
I suppose it is a good sign that I’m having a hard time keeping up with all of the recent media coverage of climate change. I would like to point out though that while the coverage is now consistent via the web I’m not seeing it nearly as much on the television. I don’t watch much but when I do flip on the TV and CNN I’m much more likely to see discussion of stupid, irrelevant celebrity gossip than I am discussion of climate change. That’s just plain fucked up. Until the corporate media stop the daily bullshit coverage of Anna Nicole’s baby’s daddy and replace it with daily discussion of peak oil, climate change, and sustainable development they are as much a part of the problem as they have always been.

The impact of climate change has been a major source of dispute
Billions of people face shortages of food and water and increased risk of flooding, experts at a major climate change conference have warned.
Damage already done for some natural wonders
BRUSSELS, Belgium (AP) – While governments grapple with the politics of global warming, some of the world’s greatest treasures already are being damaged and threatened with destruction.
Conservationists have drawn up priorities for action to salvage some of nature’s wonders that are feeling the heat of climate change – from the Himalayan glaciers to the Amazon rain forests and the unique ecosystem of the Mexican desert.
Many of the regions at risk were singled out in a report by the Intergovernmental Panel on Climate Change, an authoritative body of 2,500 scientists. The report is undergoing governmental review at a five-day conference in Brussels.
On Thursday, diplomats and scientists were negotiating the text of a 21-page summary of the full 1,572-page scientific report. It projects specific consequences for each degree of rising global temperatures, which the IPCC agrees is largely caused by human activity.
On the sidelines of the conference, the World Wildlife Fund for Nature issued a list of 10 regions suffering irreversible damage from climate change. The group also listed where it has projects to limit further damage or help people adapt to new conditions.
“What we are talking about are the faces of the impacts of climate change,” said Lara Hansen, WWF’s chief scientist on climate issues.
The WWF is among the largest of many nongovernment organizations to take up the challenge of climate change.
The Nature Conservancy, based in Arlington, Virginia, is another. It has projects to protect coral reefs off Florida, in the coral triangle of Indonesia and in Papua New Guinea. It also is trying to preserve native alpine meadows in China and conserve vegetation in California’s Sierra Nevada mountains.
Though climate change has been discussed for decades, Hansen said the effects were now becoming visible. “It’s only in the past decade that we can go outside and see for ourselves what’s happening,” she told The Associated Press.
Some damage is reversible, Hansen said. Although melted glaciers cannot be restored, some coral reefs can recover.
But as natural landmarks deteriorate, she said more attention will have to be paid to adapting to change, not only trying to prevent it, and not enough experts are being trained to help people acclimatize.
“There’s a massive void ahead of us in getting new people,” she said.
U.N.: Warming ruining society, nature:
Top climate experts warned on Friday that global warming will cause faster and wider damage than previously forecast, ranging from hunger in Africa and Asia to extinctions and rising ocean levels.
Study: Climate change could bring new U.S. Dust Bowl
Changing climate will mean increasing drought in the southwestern United States, where water already is in short supply, according to a new study.
“The bottom line message for the average person and also for the states and federal government is that they’d better start planning for a Southwest region in which the water resources are increasingly stretched,” said Richard Seager of Columbia University’s Lamont Doherty Earth Observatory.
Seager is lead author of the study published online Thursday by the journal Science.
Researchers studied 19 computer models of the climate, using data dating back to 1860 and projecting into the future. The same models were used in preparing the reports of the Intergovernmental Panel on Climate Change.
The consensus of the models was that climate in the southwestern United States and parts of northern Mexico began a transition to drier conditions late in the 20th century and is continuing the trend in this century, as climate change alters the movement of storms and moisture in the atmosphere.
The reduction in rainfall could reach levels of the 1930s Dust Bowl that ranged throughout the Midwestern United States, Seager said in a telephone interview.
Arctic lost part of its perennial sea ice in 2005: NASA
Global warming may already be having an effect on the Arctic which in 2005 only replaced a little of the thick sea ice it loses and usually replenishes annually, a NASA study said Tuesday.Scientists say Antarctic ice sheet is thinning
Scientists from the US space agency used satellite images to analyze six annual cycles of Arctic sea ice from 2000 to 2006.
Sea ice is essential to maintaining and stabilizing the Arctic’s ice cover during its warmer summer months.
But “recent studies indicate Arctic perennial ice is declining seven to 10 percent each decade,” said Ron Kwok from NASA’s Jet Propulsion Laboratory in Pasadena, California.
“Our study gives the first reliable estimates of how perennial ice replenishment varies each year at the end of the summer.
“The amount of first-year ice that survives the summer directly influences how thick the ice cover will be at the start of the next melt season."
The team observed that only 4.0 percent, about 2.5 million square kilometers (965,000 square miles) of thin ice survived the 2005 summer melt to replenish the perennial cover.
It was the weakest ice cover since 2000, and so there was 14 percent less permanent ice cover in January 2006 than in the corresponding period the year before.
“The winters and summers before fall 2005 were unusually warm,” Kwok said. “The low replenishment seen in 2005 is potentially a cumulative effect of these trends.
“If the correlations between replenishment area and numbers of freezing and melting temperature days hold long-term, it is expected the perennial ice coverage will continue to decline."
Records dating back to 1958 have shown a gradual warming of Arctic temperatures which speeded up in the 1980s.
“Our study suggests that on average the area of seasonal ice that survives the summer may no longer be large enough to sustain a stable, perennial ice cover, especially in the face of accelerating climate warming and Arctic sea ice thinning,” Kwok added.
A Texas-sized piece of the Antarctic ice sheet is thinning, possibly due to global warming, and could cause the world’s oceans to rise significantly, polar ice experts said on Wednesday.
They said “surprisingly rapid changes” were occurring in Antarctica’s Amundsen Sea Embayment, which faces the southern Pacific Ocean, but that more study was needed to know how fast it was melting and how much it could cause the sea level to rise.
The warning came in a joint statement issued at the end of a conference of U.S. and European polar ice experts at the University of Texas in Austin.
The scientists blamed the melting ice on changing winds around Antarctica that they said were causing warmer waters to flow beneath ice shelves.
The wind change, they said, appeared to be the result of several factors, including global warming, ozone depletion in the atmosphere and natural variability.
The thinning in the two-mile-(3.2-km)- thick ice shelf is being observed mostly from satellites, but it is not known how much ice has been lost because data is difficult to obtain on the remote ice shelves, they said.
Study is focusing on the Amundsen Sea Embayment because it has been melting quickly and holds enough water to raise world sea levels six meters, or close to 20 feet, the scientists said.
Antarctic Glaciers' Sloughing Of Ice Has Scientists at a Loss
Some of the largest glaciers in Antarctica and Greenland are moving in unusual ways and are losing increased amounts of ice to the sea, researchers said yesterday.
–
Complicating the situation for those studying Antarctica, some parts of the continent are gaining ice depth through snowfall while temperatures on the tip of the Antarctic peninsula, the continent’s closest point to South America, are rising faster than almost anywhere else on the planet. The surprisingly fast-moving glaciers are largely on the West Antarctic ice sheet.
Wingham, of University College London, and Andrew Shepherd of the University of Edinburgh said satellite radar readings show that overall, each year the ice loss from Greenland and Antarctica amounts to about 10 percent of the rise in the global sea level, which totals about one-tenth of an inch per year. The net loss of Antarctic ice is estimated to be 25 billion metric tons a year, despite the growth of the ice sheet in East Antarctica.
Because such a large percentage of the world’s ice is found in those two locations, scientists are carefully watching for signs of increased ice loss. If that process accelerates, researchers say, it could result in a substantial, and highly disruptive, increase in sea levels worldwide.
In Greenland, glaciers appear to be moving more quickly to sea because melting ice has allowed the sheet to slide more easily over the rock and dirt below. In Antarctica, the loss is believed to be associated with the breaking off into seawater of ice deep under the ice sheet with little-understood internal dynamics that put increased pressure on the massive ice streams.
Southern Ocean current faces slowdown threat
The impact of global warming on the vast Southern Ocean around Antarctica is starting to pose a threat to ocean currents that distribute heat around the world, Australian scientists say, citing new deep-water data.
Melting ice-sheets and glaciers in Antarctica are releasing fresh water, interfering with the formation of dense “bottom water,” which sinks 4-5 kilometers to the ocean floor and helps drive the world’s ocean circulation system.
2006 Set to be 6th Warmest Worldwide
Via Common Dreams/Reuters, 2006 Set to be 6th Warmest Worldwide: UK Report:
This year is set to be the sixth warmest worldwide since records began, stoked by global warming linked to human activities, the British Meteorological Office and the University of East Anglia said on Thursday.
As England basks in unseasonably warm December weather two weeks before the end of the year, the Met Office said data from January to November made 2006 the warmest on record for central England.
“Worldwide, the provisional figures for 2006 using data from January to November, place the year as the sixth warmest year” since records began in the 1850s, the report said.
The previous warmest years were 1998 and 2005, according to the World Meteorological Organization (WMO). The WMO was due to release its own 2006 figures later on Thursday.
“The top 10 warmest years have all occurred in the last 12 years,” it said, adding that 2006 could have been warmer but for La Nina, a cooling of parts of the Pacific Ocean.

Of politics and a warming planet
Regarding the recent U.S. elections Ted Glick writes that it was Not the Revolution, But an Opening:
Fundamental, revolutionary, political and social change is clearly needed in the USA and the world. Corporate domination of the economic and political system and mass culture is a huge threat to the possibilities for a decent and sustainable future for humankind and for all forms of life on the earth.
King Coal and Big Oil continue to use their power and vast wealth to keep us locked into a reliance on earth-heating fossil fuels that, if not quickly reversed, will lead to a steady escalation of catastrophic climate events and a breakdown of an already-stressed ecosystem.
The dominance of the Pentagon and corporate-supporting, militaristic approaches to problems, the immense amounts of money wasted in weapons production, robs the masses of people of badly-needed resources for housing, health care, education and economic development. It also generates armed resistance, including the terrorism of the stateless that, in a nuclear age, is indeed terrifying.
Yeah, a very small opening and frankly I’m not too hopeful that this new congress will do squat because there’s not much new about it. I’d agree that fundamental, revolutionary political and social change are needed.
Randolph Schmid writing for the AP reports on news that will surprise no one: Signs of warming continue in the Arctic:
Signs of warming continue in the Arctic with a decline in sea ice, an increase in shrubs growing on the tundra and rising concerns about the Greenland ice sheet.
“There have been regional warming periods before. Now we’re seeing Arctic-wide changes,” James Overland, an oceanographer at the Pacific Marine Environmental Laboratory in Seattle, said Thursday.
For the past five years, it was at least 1.8 degrees Fahrenheit above average over the Arctic over the entire year, he said.
The new “State of the Arctic” analysis, released by the National Oceanic and Atmospheric Administration, also reports an increase in northward movement of warmer water through the Bering Strait in 2001-2004. This may have contributed to a continuing reduction of sea ice.
During that time, there were record lows in sea ice coverage in the region, Overland said. This year there was more normal coverage in the Bering area but a record low on the Atlantic side of the Arctic.
In the past when such a shift occurred, there would have been no net loss of ice overall, just a change in where there was a smaller amount. Now, however, there is both the shift and an overall net loss of ice, he said.
Indeed, the report said Arctic sea ice coverage this past March was the lowest in winter since measurements by satellite began in the early 1970s.
Jacqueline A. Richter-Menge of the Cold Regions Research and Engineering Laboratory in Hanover, N.H., said the sea ice decline is now being observed in both winter and summer.
Yet another pile of reasons to put George Bush and his cronies in jail. Will be interesting to see what the Supreme Court does with this: High court to hear global warming case:
The Supreme Court hears arguments this week in a case that could determine whether the Bush administration must change course in how it deals with the threat of global warming.
A dozen states as well as environmental groups and large cities are trying to convince the court that the Environmental Protection Agency must regulate, as a matter of public health, the amount of carbon dioxide that comes from vehicles.
Carbon dioxide is produced when fossil fuels are burned. It is the principal “greenhouse” gas that many scientists believe is flowing into the atmosphere at an unprecedented rate, leading to a warming of the earth and widespread ecological changes.
The Bush administration intends to argue before the court on Wednesday that the EPA lacks the power under the Clean Air Act to regulate carbon dioxide as a pollutant. The agency contends that even if it did have such authority, it would have discretion under the law on how to address the problem without imposing emissions controls.
More concerning the Supreme Court and climate change from this article by Greg Stohr: Nobel Laureates Back Case Pushing Bush to Act on Global Warming:
Environmentalists concerned about global warming want the U.S. Supreme Court to turn up the heat on President George W. Bush.
The justices, taking their first plunge into the debate over emissions that scientists blame for increasing the Earth’s temperature, hear arguments Nov. 29 in a case brought by conservation groups and 12 states. Their goal is to force Bush’s Environmental Protection Agency to regulate so-called greenhouse- gas emissions from new cars and trucks.
Bush argues that the government needs more scientific evidence before it acts against such emissions. A victory for environmentalists in the case, which may scramble the court’s usual ideological lineup, would “light a fire'' under the administration, says Carol Browner, who headed the EPA under President Bill Clinton.
“They will have no choice but to get going,'' says Browner, who – along with a group of scientists that includes two Nobel laureates – is supporting the states and environmental groups.
That might add new burdens on automakers, including Detroit- based General Motors Corp. and Dearborn, Michigan-based Ford Motor Co., and may also lead to tougher rules for coal-fired power plants.
Shortly after Bush took office in 2001, he rejected the 1997 Kyoto Protocol on greenhouse gases on the grounds that the agreement would cost jobs and hurt the U.S. economy. In 2003, the EPA declined to regulate carbon emissions, citing “substantial scientific uncertainty'' about the effects of climate change and the most efficient means to deal with it.
George Monbiot: Drastic Action on Climate Change is Needed Now - and Here’s the Plan:
The government must go further, and much faster, in its response to the moral question of the 21st century
It is a testament to the power of money that Nicholas Stern’s report should have swung the argument for drastic action, even before anyone has finished reading it. He appears to have demonstrated what many of us suspected: that it would cost much less to prevent runaway climate change than to seek to live with it. Useful as this finding is, I hope it doesn’t mean that the debate will now concentrate on money. The principal costs of climate change will be measured in lives, not pounds. As Stern reminded us yesterday, there would be a moral imperative to seek to prevent mass death even if the economic case did not stack up.
But at least almost everyone now agrees that we must act, if not at the necessary speed. If we’re to have a high chance of preventing global temperatures from rising by 2C (3.6F) above preindustrial levels, we need, in the rich nations, a 90% reduction in greenhouse-gas emissions by 2030. The greater part of the cut has to be made at the beginning of this period. To see why, picture two graphs with time on the horizontal axis and the rate of emissions plotted vertically. On one graph the line falls like a ski jump: a steep drop followed by a shallow tail. On the other it falls like the trajectory of a bullet. The area under each line represents the total volume of greenhouse gases produced in that period. They fall to the same point by the same date, but far more gases have been produced in the second case, making runaway climate change more likely.
So how do we do it without bringing civilisation crashing down? Here is a plan for drastic but affordable action that the government could take. It goes much further than the proposals discussed by Tony Blair and Gordon Brown yesterday, for the reason that this is what the science demands.
1. Set a target for reducing greenhouse-gas emissions based on the latest science. The government is using outdated figures, aiming for a 60% reduction by 2050. Even the annual 3% cut proposed in the early day motion calling for a new climate change bill does not go far enough. Timescale: immediately.
2. Use that target to set an annual carbon cap, which falls on the ski-jump trajectory. Then use the cap to set a personal carbon ration. Every citizen is given a free annual quota of carbon dioxide. He or she spends it by buying gas and electricity, petrol and train and plane tickets. If they run out, they must buy the rest from someone who has used less than his or her quota. This accounts for about 40% of the carbon dioxide we produce. The remainder is auctioned off to companies. It’s a simpler and fairer approach than either green taxation or the EU’s emissions trading scheme, and it also provides people with a powerful incentive to demand low-carbon technologies. Timescale: a full scheme in place by January 2009.
3. Introduce a new set of building regulations, with three objectives. A. Imposing strict energy-efficiency requirements on all major refurbishments (costing £3,000 or more). Timescale: in force by June 2007. B. Obliging landlords to bring their houses up to high energy-efficiency standards before they can rent them out. Timescale: to cover all new rentals from January 2008. C. Ensuring that all new homes in the UK are built to the German Passivhaus standard (which requires no heating system). Timescale: in force by 2012.
4. Ban the sale of incandescent lightbulbs, patio heaters, garden floodlights and other wasteful and unnecessary technologies. Introduce a stiff “feebate” system for all electronic goods sold in the UK, with the least efficient taxed heavily and the most efficient receiving tax discounts. Every year the standards in each category rise. Timescale: fully implemented by November 2007.
5. Redeploy money now earmarked for new nuclear missiles towards a massive investment in energy generation and distribution. Two schemes in particular require government support to make them commercially viable: very large wind farms, many miles offshore, connected to the grid with high-voltage direct-current cables; and a hydrogen pipeline network to take over from the natural gas grid as the primary means of delivering fuel for home heating. Timescale: both programmes commence at the end of 2007 and are completed by 2018.
6. Promote the development of a new national coach network. City-centre coach stations are shut down and moved to motorway junctions. Urban public transport networks are extended to meet them. The coaches travel on dedicated lanes and never leave the motorways. Journeys by public transport then become as fast as journeys by car, while saving 90% of emissions. It is self-financing, through the sale of the land now used for coach stations. Timescale: commences in 2008; completed by 2020.
7. Oblige all chains of filling stations to supply leasable electric car batteries. This provides electric cars with unlimited mileage: as the battery runs down, you pull into a forecourt; a crane lifts it out and drops in a fresh one. The batteries are charged overnight with surplus electricity from offshore wind farms. Timescale: fully operational by 2011.
8. Abandon the road-building and road-widening programme, and spend the money on tackling climate change. The government has earmarked £11.4bn for road expansion. It claims to be allocating just £545m a year to “spending policies that tackle climate change”. Timescale: immediately.
9. Freeze and then reduce UK airport capacity. While capacity remains high there will be constant upward pressure on any scheme the government introduces to limit flights. We need a freeze on all new airport construction and the introduction of a national quota for landing slots, to be reduced by 90% by 2030. Timescale: immediately.
10. Legislate for the closure of all out-of-town superstores, and their replacement with a warehouse and delivery system. Shops use a staggering amount of energy (six times as much electricity per square metre as factories, for example), and major reductions are hard to achieve: Tesco’s “state of the art” energy-saving store at Diss in Norfolk has managed to cut its energy use by only 20%. Warehouses containing the same quantity of goods use roughly 5% of the energy. Out-of-town shops are also hardwired to the car - delivery vehicles use 70% less fuel. Timescale: fully implemented by 2012.
These timescales might seem extraordinarily ambitious. They are, by contrast to the current glacial pace of change. But when the US entered the second world war it turned the economy around on a sixpence. Carmakers began producing aircraft and missiles within a year, and amphibious vehicles in 90 days, from a standing start. And that was 65 years ago. If we want this to happen, we can make it happen. It will require more economic intervention than we are used to, and some pretty brutal emergency planning policies (with little time or scope for objections). But if you believe that these are worse than mass death then there is something wrong with your value system.
Climate change is not just a moral question: it is the moral question of the 21st century. There is one position even more morally culpable than denial. That is to accept that it’s happening and that its results will be catastrophic, but to fail to take the measures needed to prevent it.
Regarding the recent climate talks, we have a long way to go and… it does not look good. Slow Talks Could Leave Climate Deal in ‘Tatters’
A new global agreement to tackle climate change may be scuppered by cumbersome international bodies and a lack of political will, David Miliband, the Environment Secretary, fears.
He warned that politics was now lagging dangerously behind the science on global warming and feared that negotiations on a new deal might drag on so long that there would be a “gap” in 2012 when the Kyoto protocol’s first stage runs out.
To ensure deeper cuts in carbon emissions from then, he said, agreement in principle would be needed by the end of next year. “If we have a gap in 2012, we would have a very serious problem. The whole system would be in tatters,” he said.
Mr Miliband was speaking yesterday after returning from a United Nations conference in Kenya involving 189 countries, which ended without a major breakthrough but agreed to keep talking about a “son of Kyoto” treaty.
In an interview with The Independent, he said: “The political institutions and their speed are out of sync with the scientific needs of the issue. There was real progress on important issues in Nairobi but the gap between the science and the politics remains large, with industrialised and developing countries divided by priorities and divided among themselves."

Peak Oil and Climate Change Round-up
From the NewScientist we read the news that Carbon emissions rising faster than ever:
Far from slowing down, global carbon dioxide emissions are rising faster than before, said a gathering of scientists in Beijing on Friday.
Between 2000 and 2005, emissions grew four times faster than in the preceding 10 years, according to researchers at the Global Carbon Project, a consortium of international researchers. Global growth rates were 0.8% from 1990 to 1999. From 2000 to 2005, they reached 3.2%.
What can be said? I’ll try to be positive. Each and every day presents opportunities in the form of choices that we can make to reduce the amount of carbon we contribute. There is no doubt that time is running out or already has. The time to act is NOW.
Jim Kunstler over at Clusterfuck Nation has a great post on the scope and meaning of real Energy Independence.
There’s also this story out of London regarding Labour Party leader Michael Mearcher who suggests that England needs to be on war footing against global warming:
This is the one overriding overall political issue which challenges the future of the human species on this planet.
I could not agree more. I tend to not think about organizing our human activities on a “war” footing but I understand the meaning. This needs to be the TOP priority in all our human endeavors. Each and every one of us should wake up everyday thinking about what we can do to stop global warming. The human race must by unified in it’s pursuit of this one primary goal.

Time travel and climate change
In reply to my last post Kyle asked:
Denny, you and I and many others know that there is nothing natural about the rate and the way in which the Earth is warming…. especially when the catastrophic affects are so scary. I was wondering how you go about convincing others who believe the warming of the Earth is a natural part of the Earth’s “cycles.” I only say this because there is a NASA quote in your piece that reads, “Earth’s temperature could be reaching it’s highest level in a million years”….therefore, it would be easy for someone to say….so the Earth got just as hot (or hotter) a million years ago. I’m just curious because whenever I get into this with someone, it always comes up….and I don’t have an answer.
My reply to this specifically is that yes there natural cycles but a) the current warming is not one of them and b) just because there are natural warming and cooling cycles over the course of millions of years it’s not likely that such cycles would be easy to survive, even for humans. People want to discount human caused climate change because people, especially those in western, “civilized”, nations don’t want to face the change it might require to their lifestyle. At least, that’s my take and I think there’s a good bit of truth to it. Does it really matter if the earth has been this hot before? No. What matters, at least from a very selfish human perspective, is will humans survive? We seem to think that we are special because of our ability to create technology but it is a mistake to assume that technology will save us.
The fact that the earth was warmer a million years ago should offer no comfort at all. With the exception of a small handful of scientists the vast majority of us have no clue at what this really means in terms of a livable planet. Not a damn clue. As an example, how does a warmer earth effect insect populations which in turn effect agricultural systems? That’s just one small consideration and it’s not small at all… the implications on human food supply are quite large. Add to that the effects of other variables that are likely to be changing such as weather patterns and it’s not hard to see that we will likely be facing a food crisis never seen before. The effects of a significantly warmer earth are mind boggling.
Some still seem to think we are capable of rational thought though I’m starting to question that… we’re certainly capable of rationalizing. The question regarding a warmer climate is what does it mean for our survival? That really is the question. Really. Will we survive. We’re not talking about the far distant future. We are talking about 30 - 100 years. Our lifetimes, our children’s lifetimes. Strange and sad that such an important question is so quickly glossed over by most people. It’s easier to lie to ourselves and our children than face the inconvenient truth. Al Gore could not have picked a better title for his movie. Actually, the truth will prove to be far, far worse than inconvenient.
Something I’ve found at least somewhat effective in communicating the importance and the immediacy of climate change is time travel. Yes, time travel. You didn’t know you could did you. No, I’m not crazy. I’m talking about our ability to think, to envision. Try this easy exercise with yourself, friend, family member or co-worker. Just sit for a minute and really allow yourself to think about today and the effects we’ve seen from climate change already. Retreating glaciers, melting ice caps… the list is long and is being reported in new studies every month. Now, we’re ready for the time travel. Ask yourself, what will it look like in 10 years? 20 years? 30 years? Ponder that future and how the climate of that time may be affecting the planet. Now imagine yourself, in that future looking back to 2006. What would that future self ask? I think the people of the future will look back and wonder why? Why did people not act? They will wonder why we ignored the evidence, the symptoms. They will condemn not our ignorance (because we are not ignorant) but our stupidity.
We cannot time travel to the future but we can attempt to wonder what it will look like and we can create a vision that is at least somewhat likely. We cannot know exactly how the climate will look in 2036 but it seems worth the effort to ponder it. Is it the world we want for today’s children? I find that folks that will take a few minutes to really ponder the future might be more inclined to deal with their own contributions to climate change today.
I’ve heard more than a few people say… “If only I had know I would have done something.” Well, we do know. We know right now at this moment. We are not ignorant and there is no excuse. We can face the future we are creating today and we can have power over it.
One last thing. If we want to change our future we have to do it now with direct action. Individually and collectively we must take responsibility. This is not about waiting for the government to fix things. We do not need the government to force us to do what we need to do. To say that unless the government makes laws to enforce broad behavior change is lazy and it is shirking OUR responsibility. Governments have failed on this and in particular, the U.S. government, bought and paid for by the energy industry has failed. No, we cannot wait for the government. We can do this ourselves. We must lead in the way we live our lives every day. As individuals and in our communities we can create the change that needs to happen.
Turn off the devices that you don’t need. Ride a bike. Carpool. Grow your own food. If you absolutely must drive accelerate slowly, coast to stops, keep it at 60 mph on the highway. Conserve in every way possible in every aspect of your life. Do it yourself and do it with others in your community. Share. Cooperate. We can do this.

Climate change and global consumption
Been far too long since I put up a post regarding the impending doom that is climate change. Actually, impending is the wrong word because that implies that it has yet to arrive. No, it’s already here. Climate change and its effects are right now, not the future. Of course climate change is a direct result of our rapid over consumption of natural resources. We’ll start with the BBC which reports on Global ecosystems collapse:
Current global consumption levels could result in a large-scale ecosystem collapse by the middle of the century, environmental group WWF has warned.The Guardian reports on NASA scientests warning that Earth’s temperature is dangerously high:
The group’s biannual Living Planet Report said the natural world was being degraded “at a rate unprecedented in human history”.
Terrestrial species had declined by 31% between 1970-2003, the findings showed.
It warned that if demand continued at the current rate, two planets would be needed to meet global demand by 2050.
The biodiversity loss was a result of resources being consumed faster than the planet could replace them, the authors said.
Earth’s temperature could be reaching its highest level in a million years, American scientists said yesterday.Also from NASA, we have only a decade left to act in time:
Researchers at Nasa’s Goddard Institute for Space Studies said a further one degree celsius rise in the global temperature could be critical to the planet, and there was already a threat of extreme weather resulting from El Niño.
The scientists said that in the 30 years to the end of 2005, temperatures increased at the rate of 0. 2 degrees per decade, a rate they described as “remarkably rapid”.
Comparison of the current global temperature with estimates of historical temperatures - based on a study of ocean sediment - showed the current temperature was now within 1C of the maximum temperature of the past million years.
Dr James Hansen, who led the study, said further global warming of just 1C could lead to big changes to the planet.
“If warming is kept less than that, effects of global warming may be relatively manageable,” he said.
“But if further global warming reaches two or three degrees celsius, we will likely see changes that make Earth a different planet [to] the one we know.
“The last time it was that warm was in the middle Pliocene, about 3m years ago, when sea level was estimated to have been about 25 meters (80 feet) higher than today."
‘We have a very brief window of opportunity,’ NASA scientist says
A leading U.S. climate researcher says the world has a 10-year window of opportunity to take decisive action on global warming and avert catastrophe.
NASA scientist James Hansen, widely considered the doyen of American climate researchers, said governments must adopt an alternative scenario to keep carbon dioxide emission growth in check and limit the increase in global temperatures to 1 degree Celsius (1.8 degrees Fahrenheit).
“I think we have a very brief window of opportunity to deal with climate change … no longer than a decade, at the most,” Hansen said Wednesday at the Climate Change Research Conference in California’s state capital.
If the world continues with a “business as usual” scenario, Hansen said temperatures will rise by 2 to 3 degrees Celsius (3.6 to 7.2 degrees F) and “we will be producing a different planet.”
On that warmer planet, ice sheets would melt quickly, causing a rise in sea levels that would put most of Manhattan under water. The world would see more prolonged droughts and heat waves, powerful hurricanes in new areas and the likely extinction of 50 percent of species.
