The Cost of Controlling Climate Change
April 03, 2008 2:08 PM
A veteran climate scientist, a policy analyst and an economist say it will be far more expensive than the Intergovernmental Panel on Climate Change estimated to cut down on the greenhouse gases often blamed for the problem.
They've published a commentary in today's edition of NATURE, saying the IPCC may actually be too optimistic by a factor of four. (Yes, the IPCC is the organization that shared last year's Nobel Peace Prize with a certain political figure.)
The authors are Roger Pielke Jr. of the University of Colorado, Tom Wigley of the National Center for Atmospheric Research, and Christopher Green of McGill University in Montreal.
"Two thirds or more of the energy efficiency improvements and decarbonization of energy supply required to stabilize greenhouse gases is already built into the IPCC reference scenarios," they write, adding that growth in China and India have made things more complex. "The IPCC plays a risky game in assuming that spontaneous advances in technological innovation will carry most of the burden of achieving future emissions reductions, rather than focusing on creating the conditions for such innovations to occur." Find the full text HERE.
There's also a news article on it at Nature.com, which you can find HERE.
All three men are on record as saying warming is not to be ignored. "Human-caused climate change is real and requires attention by policy makers to both mitigation and adaptation -- but there is no quick fix; the issue will be with us for decades and longer," Pielke wrote in testimony to the House Government Reform Committee in 2006.
But the warning in today's commentary is hotly disputed by Joseph Romm, who worked in the Energy Department in the 1990s and is the author of "Hell and High Water--and What You Should Do." Romm calls Pielke a "delayer" of action on climate, and calls the commentary "pointless and misleading if not outright dangerous."
"Five years ago the American Enterprise Institute “proved” that the lowest IPCC emissions projection is too high, and they backed up their conclusion with actual 1990s data, whereas Pielke, Wigley, and Green have “proven” that the highest IPCC emissions projection is too low, and they backed up their conclusion with actual data from this decade," he writes. He goes into some detail in his post at ClimateProgress.org; read it HERE.
This is dense stuff. It helps you understand why the climate issue is such a turnoff to a lot of people. But in the meantime, Fred Krupp, president of the Environmental Defense Fund has, with Miriam Horn, published an upbeat book called "Earth: the Sequel." In it, they lay out dozens--if not hundreds--of promising ideas which they say will help stop warming...and make their inventors rich in the process.
"Twenty years from now some thirty-five-year-old is going to say the reason he's a billionaire is that he read this book when he was fifteen," writes Michael Lewis ("The New New Thing") in a jacket blurb. At last count, the book was number 28 on the New York Times nonfiction-hardcover bestseller list.

Hillary Clinton leads the way in support of policies that will create a Green economy in our future. This is a no-brainer way to go to head off global warming. I don't see anybody else doing or saying anything that helps us.

Rather than argue about how much it will cost, why don't we just DO it and find out for ourselves? The one thing we do know for sure is that it will cost us a lot more the longer we delay.
There are a great many people who have been working on ways to do this the smart way, so it is fair to everyone and has the best chance of helping our economy in the long run. We know how to do it; we just need the will.

Bla Bla Bla; Another day, another way to perpetuate the global warming myth.

Doing anything without being fully informed could easily backfire on us as many of our past "good environmental intentions" have done. This may well be a very bad time to combat AGW.
Posted by: Quietman | Apr 3, 2008 4:45:10 PM
That does seem like a decent site. Of course it mostly SUPPORTS AGW, so you'll have to be more specific on where it says we shouldn't be combatting it right now.
I'm also not sure which solutions you think might "backfire." If you mean the silly things like dumping iron in the ocean, I don't think anyone is taking that too seriously. But mostly we are talking about energy efficiency and alternative fuels, which are not likely to "backfire," at least if we do them right.

Global Warmimg is very definitely NOT a myth.
Ice sheets melting - Yes
Planetary Temperature rising - Yes
Has this happened before - Yes
Can it happen again - Yes
Has the planet experienced cooling before - Yes
Just a few facts, not enough to confuse even the most rabid fanatic.
The problem of Global Warming is a real example of what happens when a subject becomes politicised long before all the facts are known.
Mankind certainly is not helping but that's not the problem. The real problem is sorting out long term (several hundreds or thousands of years) trend data from the short term (decades) noise.
Do the science, separate it from the politics and lets all use less energy.
The only other thing we have to do is somehow relocate those that are displaced by the rise in sea level and perhaps protect some areas from inundation by the sea. Anything else is just posturing.
Posted by: Andy Clark | Apr 3, 2008 5:10:37 PM
Bah, let them be inundated. We've got too many people on the planet then the planet can support. If we didn't, then we wouldn't have all the starving people in the third world countries. But that's a whole other topic.
As for global warming....well, I have come to the conclusion that it is a natural cycle of the planet. Have we affected it? Yea, but I don't think we've affected it to the extent most people think. Should we be better stewards of our planet? Yea, right now we are the ######### at it. How do we do it? Stop using fosil fuels and switch to Nuclear and Hydrogen. Store the Nuke waste somewhere, we may find a practical use for it in the future.

A worthless economy is what it will cost with the cap and trade. Our costs of gasoline and heating our homes will go through the roof, is what it will cost. Look at some of the proposed carbon taxes put on gasoline, heating fuel and electrisity. That alone will cripple the economy and most of the families just squeaking by now.

In the answers to the comments. The site examines skepticism and attempts to provide answers. Very open and apparently honest. Also the links peovided in the comments are often well worth the read. The only problem is that it is in the UK so there is an overnight lag in responses.

peovided s/b provided - sorry.

Re: "energy efficiency and alternative fuels"
This is very relavent. The UK started and then stopped the rush to alternative fuels recently, realizing that it needs more study.
Personally I think that switchgrass is the answer that we want, both because it does not take away food and increase the cost of food in doing so and also because it can grow on land that can not be used for growing food crops. But then there are still emissions to think about. Have you ever visited a drag strip where they were running alcohol based fuels? The raw emissions are much worse than fossil fuel emissions. What new contaminants will be produced from their controlled emissions?
And we do have the time to investigate as nature is helping to negate the warming at this time and will probably give us a few years relief.

My sentiments as well.

This time you hit the nail on the head.
Economics and mistrust of politicians are the main concerns of most skeptics.
Posted by: Quietman | Apr 3, 2008 7:30:25 PM
Quietman-
What I am more concerned about is the mistrust of scientists, engendered by the PR firms of first the tobacco industry and now the oil industry (often the same PR firms). Much of the "science" that skeptics throw around was manufactured out of this industry. The anti-intellectualism it feeds into really scares me.
Posted by: jock59801 | Apr 3, 2008 8:57:02 PM
Quietman-
One thing most people seem to agree on is that there is no "one" answer. And also that corn-based ethanol probably does more harm than good. But energy efficiency is always a good idea, and we have a large portfolio of alternatives that need to be used in a smart way. Wind, solar, and biofuels all have their place. Cellulosic ethanol using switchgrass also has good promise but still needs work. Biodiesel from oil-producing algae has even more potential. The more we move the financial incentives over to these technologies the faster they will come online. And no, I don't think we can risk any delays.
Posted by: jock59801 | Apr 3, 2008 9:03:38 PM
The time to act is NOW. Personally, I favor a multi-pronged approach. Have one consortium look into solar, another into wind, another into nuclear, etc. Sooner or later, someone is going to come up with a viable answer. One thing for sure: Sitting on our respective thumbs and "studying" the problem is going to do nothing.

Jock59801,
Anti-intellectualism isn't new, it's just found a new voice in modern communications.

Go -- NUCLEAR
Mass electrical power in bulk, NO CO2.
Posted by: stevie B | Apr 4, 2008 1:37:19 AM
Andy & Jock
The best possible solution with current technology is nuclear. Too bad most of the plans were scrapped because of fear.
Posted by: Quietman | Apr 4, 2008 1:39:58 AM
Before anyone takes "the cost of climate change" seriously, we have to believe climate change is happening, and is caused by humans. Many people seem to doubt this, but there are several facts that are hard to ignore. In the past 150 years, human activity has released a tremendous amount of CO2 that had been locked away as oil for many thousands of years. Temperatures around the world, along with atmospheric CO2 measurements have been going up since the 1970s, with acceleration in the 1990s. The cause-and-effect relationship is well-known: CO2 absorbs infrared radiation emanating from the Earth and converts it to heat in the atmosphere. Increasing the amount of CO2 in the atmosphere increases the amount of atmospheric heating.
