Climate 411

It’s no surprise that some opponents of clean energy legislation are fighting dirty. Big Polluters were always expected to use underhanded tactics, and they’ve managed to live up (or down) to the stereotype. But in the last week or so, the opposition’s pronouncements have veered from merely misleading to downright wacky.

We like to think it’s a sign of desperation triggered by the other side’s knowledge that they’re losing. However you want to interpret it, here are four quotes that will make your jaw drop:

Pennsylvania State Senator Daryl Metcalfe

As a veteran, I believe that any veteran lending their name to promote the leftist propaganda of global warming and climate change … is a traitor to the oath he or she took to defend the Constitution of our great nation! Remember Benedict Arnold before giving credibility to a veteran who uses their service as a means to promote a leftist agenda. Drill Baby Drill!!!

Senator Metcalfe wrote that about Operation Free, a group of decorated war veterans who are traveling the country to talk about the importance of energy independence to our national security. Operation Free pointed out that “the Department of Defense, the Department of State, the National Intelligence Council, and the Central Intelligence Agency have all decided that climate change is a security threat that must be dealt with seriously and honestly” – but Metcalfe still refuses to apologize.

Senator James Inhofe

There’s another secret person going with me. We’re going to have a team of three, a truth squad of three.

Senator Inhofe (R-OK) made that announcement on Bill Bennett’s radio show. (ThinkProgress has the clip) Inhofe had already announced that he would travel to Copenhagen to be a “one man truth-squad” during international climate change treaty negotiations. Now we know that John Barrasso is going with him and we’re anxiously awaiting the identity of the third “secret” climate change denier.

U.S. Chamber of Commerce President Tom Donohue

Members come and go all the damn time.

Donohue explains why a highly-publicized string of companies leaving the Chamber doesn’t bother him. Politico pointed out that rarely, if ever, have so many companies publicly left a business group over a policy disagreement.

Rush Limbaugh

This guy from The New York Times, if he really thinks that humanity is destroying the planet, humanity is destroying the climate, that human beings in their natural existence are going to cause the extinction of life on Earth — Andrew Revkin. Mr. Revkin, why don’t you just go kill yourself and help the planet by dying?

Limbaugh calls for the untimely demise of reporter Andy Revkin, who had the nerve to acknowledge that a rapidly increasing global population is one of the factors contributing to climate change. This hate-filled invective is par for the course for Limbaugh though, so this might not be a sign that the opposition is growing desperate. Either way, you can find a link to the comments on Media Matters.

This is a tale of serendipity.  About two brand-new books on climate, written independently, that mysteriously collide.

One of them, Superfreakonomics, manages – despite the fame and brilliance of its authors – to enthusiastically endorse two notorious misconceptions about climate science.

But here’s the serendipitous part.  Even though the authors of the second book, A Climate for Change, had never seen Superfreakonomics, they managed to write spot-on rebuttals on both points.

Freaknomics and its brand-new sequel

Unless you’ve been trapped in a bomb shelter the past few years, you’ve heard of Freakonomics, the best-selling book by a star economist (Steven Levitt) and his journalist co-author (Stephen Dubner).

Levitt, a professor at the University of Chicago, is a brilliant guy.  He’s already won a “best young economist” prize, which often foretells a future economics Nobel.  And Dubner is a gifted writer.

Freakonomics gave us colorful accounts of some of Prof. Levitt’s own quirky research.  Like his study of Japanese sumo wrestling records, which showed that top-rank wrestlers deliberately lose certain matches to help their opponents remain in the elite top tier.  Presumably in the hope that they’ll return the favor.

So far, so good.

Now our best-selling authors have written a sequel: SuperFreakonomics: Global Cooling, Patriotic Prostitutes, and Why Suicide Bombers Should Buy Life Insurance.  Its official release date is Tuesday, October 20, 2009.

As you can guess from the title, one chapter is about climate change.  That chapter has been the subject of what diplomats would call a spirited debate over the past few days.  You can read the chapter for yourself (PDF, sorry, not the best quality).

What are people saying about the Superfreakonomics take on climate?

Well, here’s Professor Paul Krugman (who actually has a Nobel in Economics):

[T]here’s an average of one statement per page [in the Superfreakonomics chapter on climate] that’s either flatly untrue or deeply misleading.

The respected climate science blog, RealClimate.org, says this about Superfreakonomics’ proposed fix to climate change:

the reasons why Levitt and Dubner like [their solution] so much are based on a misreading of the science, a misrepresentation of proposed solutions, and truly bizarre interpretations of how environmental problems have been dealt with in the past.

And here’s The New Republic’s Brad Plumer:

Levitt and Dubner just parachute into the field of climate science and offer some lazy punditry on the subject dressed up as ‘contrarianism.’  There’s no original research.  There’s nothing bold or explosive.  It’s just garden-variety ignorance.

Then there’s economist Brad DeLong:

I have a little unsolicited advice for Levitt and Dubner.  If I were them, I would abjectly apologize.

Statistical genius Nate Silver, of FiveThirtyEight.com, says that

the chapter on climate science is by far the weakest material in either of the two Freakonomics books.

Not to mention the tireless Joe Romm of ClimateProgress:

New book pushes global cooling myths, sheer illogic, and ‘patent nonsense.’

Meanwhile, an actual climate scientist writes A Climate for Change

While an economist and a journalist were busy writing Superfreakonomics, a real-life climate scientist and geoscience professor, Prof. Katharine Hayhoe, was writing A Climate for Change.  (Actually, co-authoring it with her husband, Andrew Farley, an evangelical pastor.)  It’s out on October 29, and you can order it here.

You may not know Hayhoe, but you should.  She’s an outstanding young climate scientist, so well-regarded that she was chosen to be a principal author of the recent report by the U.S. Global Change Research Program, Global Climate Change Impacts in the United States.  And both she and her husband have golden pens.

A Climate for Change is designed to communicate to everyone – with a special focus on people of faith – what they need to know about climate change.  In plain, crisp English.

Sloppy Superfreakonomics blunders mysteriously anticipated by brilliant climate scientist

Now for the serendipity.

Superfreak blunder #1:  “Carbon dioxide doesn’t necessarily warm the earth.”

Here’s what Levitt and Dubner say on p. 183 of Superfreakonomics:

“[C]hanges in carbon dioxide levels don’t necessarily mirror human activity.  Nor does atmospheric carbon dioxide necessarily warm the earth:  ice-cap evidence shows that over the past several hundred thousand years, carbon dioxide levels have risen after a rise in temperature, not the other way around.”

That second sentence?  Though written by Levitt and Dubner, House Republican Joe Barton – a fervent climate change denier – often says the same thing.  Like the Superfreakonomics authors, Rep. Barton hasn’t done his homework.

But here’s the great part:  Hayhoe wrote the rebuttal without even seeing the Levitt/Dubner book.  Here’s your first sneak preview of A Climate for Change:

“The Chicken or the Egg?”

“[Looking at the historic record, some people say that] [c]arbon dioxide and other greenhouse gases are just following suit rather than leading the hand.  . . .”

Within this line of reasoning, there is a partial truth. So, first, let’s look at the true part.

Scientists believe that the last ice age ended thousands of years ago when Earth’s orbit shifted, altering the distribution of sunlight received by the earth. Temperatures rose a few degrees over several hundred years, with little or no change in greenhouse gases. So, as far as we can tell, it is indeed true that greenhouse gases have never initiated a climate warming before.

Now, for the rest of the truth. That initial temperature change caused by the sun was only one-third of the total temperature difference between that ice age and today. So what caused the rest of the warming?  The answer is:  carbon dioxide and other greenhouse gases.

…So the truth is that increases in carbon dioxide and other heat-trapping gases have caused temperatures to increase in the past. And realizing this has many scientists worried.  If just a slight warming caused by the sun could be amplified threefold by natural carbon dioxide . . . way back then, what might happen today?”

So much for the chicken and the egg.  What about this claim from the Superfreakonomics authors:  “Nor does atmospheric carbon dioxide necessarily warm the earth.”

Here’s what Hayhoe told me what I asked her about that today:  “That’s a complete non sequitur.  Carbon dioxide molecules absorb infrared, or heat, energy; this has been understood since the 1700s. And as far as we can tell from the data, carbon dioxide increases have always warmed the earth.  No exceptions.”

Superfreak blunder # 2:  “Global temperatures are now declining.”

On page 187 of Superfreakonomics, the authors say this:

“Then there’s this little discussed fact about global warming:  as the drumbeat of doom has grown louder over the past several years, the average global temperature reading over that time has in fact decreased.”

To call this claim “little discussed” is a bit strange.  The “global warming is over” claim is a staple of climate change deniers.  It’s a constant mantra on Fox News, among other places.  In fact, not long ago, anchor Laura Ingraham threw it at Hayhoe at the end of an interview on The O’Reilly Factor – while giving her no time to respond.

But the mantra is wrong.  And once again, Hayhoe managed to anticipate the Superfreakonomics mistake:

“No Cooling in Sight”

Despite the evidence for a warming trend from the global record, some still claim that global warming has slowed down, or that ‘it’s not much of a problem anymore,’ or even ‘It’s stopped.’  Talk of global cooling . . . has recently resurfaced.

It’s true that, if the sun alone were controlling our climate, there would be reason to suspect that we’re headed for a new ice age—eventually.  . . .

But today, we know the sun is not the only factor.  As we’ll discuss later, the idea that greenhouse gases are driving climate has been around for more than 150 years.  And this theory has been the subject of tens of thousands of scientific journal articles.

Even still, the notion of global cooling has recently resurfaced, and Figure 4 helps explain why.  This graph zooms in on global temperatures over the last fifty years.  The red line shows how temperatures have been rising from 1960 to 2010, while the blue line shows how you can use this same record to support an argument that the world actually cooled from 1998 to 2008.  Some carefully select these two data points to argue that climate change isn’t occurring.  Or they even claim that the world is cooling.

It’s true that the blue line from 1998 to 2008 slopes downward.  At first glance, one might think this suggests that global warming is slowing down.  But climate change is about what is happening across decades and centuries.  It’s certainly not about the difference between two specifically selected years, [especially when 1998 was a strong El Nino year.]

The true change in global temperature—an undeniable warming—is seen by drawing a line across multiple decades. Here, we see 1960 to 2008, for example. . . .  These longer-term graphs accurately depict the warming trend we are experiencing, and illustrate the problem with selecting two individual years that are a decade apart, connecting the dots, and then arguing for global cooling.”

By now, you’ve figured out the moral of this little story:  if you want a clear, lucid explanation of climate change, the book you want is Professor Hayhoe’s A Climate for Change.

As for Superfreakonomics, let’s wait for the second edition and see if they can get their science right.

It must have been a late night for one of the headline writers at the Washington Post. That’s the best explanation we can think of for the seriously misleading headline on a generally balanced story by reporter Juliet Eilperin.

The story is about the testimony of the head of the Congressional Budget Office, Douglas Elmendorf, who appeared before a Senate energy panel yesterday.

The article points out that Elmendorf went out of his way to say the costs of shifting to clean energy would be “comparatively modest” and that his analysis didn’t even include the heavy cost of failing to take action to slow climate change.  He estimated a very small economic difference under the clean energy bill over a long period of time.

The headline writer summed it up this way: “Cap-and-Trade Would Slow Economy, CBO Chief Says.”

This is extremely misleading since many readers will interpret this to mean that economic growth would actually turn negative, which is absolutely NOT what Elmendorf said.

What he said (and what Eilperin reported) is what’s reflected in the CBO analysis – that the economy is expected to grow strongly and thrive whether we pass a carbon cap or not. If we do nothing, the American economy would reach $25 trillion by January 2030; if we pass a cap on carbon, it will reach the exact same size of $25 trillion by May of 2030 (and that’s a conservative estimate – we’d reach that between March and May). And, remember, that projection doesn’t include the economic benefits of avoiding the worst impacts of climate change.

What is confusing in the headline is that “economy slowing” has become shorthand for “panic, it’s a recession” — which is the opposite of what Elmendorf was talking about. What Elmendorf actually said is that a cap would “cut the nation’s gross domestic product … compared to ‘what it would otherwise have been.’” The CBO finding was that a carbon cap would cut GDP “0.25 to 0.75 percent” by the year 2020. Again, that’s a cut from what it would have otherwise reached without the policy — not a cut from where the economy stands now.

To put that in perspective, if you had to cut the Post article by the same amount, you’d need to edit out – three or four words. Or, to cut that headline proportionately you’d have to – lose half the “s” on the end of the last word. That’s a tiny amount, and certainly no reason to panic – unless you’re looking for a reason to panic so you can try to kill a clean energy bill.

Read more in EDF’s latest Climate Economics Brief, Or read the CBO report itself. And check out National Wildlife Federation’s comments on, as they call it, the Post‘s “scare headlines” — we’re flattered that they used an EDF graph to help make their case.

The Chamber of Commerce story is all over the media again today, which means we get to keep using the phrase “Scopes monkey trial” almost a century after it should have been old news.

In yesterday’s blog post we told you about Apple “resigning .. effective immediately” from the Chamber because of the Chamber’s position on global warming policy. Apple became the fifth big company to leave either the Chamber or its board of directors because of inflammatory comments about the underlying truth of climate science (the others are Exelon, PG&E, PNM and Nike).

Apple’s departure touched off a slew of articles and editorials around the country, all pointing out that the Chamber has gotten itself into a public relations hole — and most suggesting that it follow the advice of the old proverb and stop digging.

Here’s a sample of the reactions:

• San Francisco Chronicle: “U.S. Chamber of Commerce Feels the Heat“
• Boston Globe: “Chamber of overstated horrors“
• Atlanta Journal-Constitution: “When Big Business does the right thing“

And the winner in the pop-culture reference department is Marc Gunther, writing for the Energy Collective, who compares the Chamber to David Letterman, because the have both “really, really embarrassed themselves.”

But the Chamber is apparently not interested in the above advice. Instead, it is digging in and has launched counterattacks against Apple and some of its other critics, including the Boston Globe.

Chamber CEO Tom Donohue told reporters, including Politico‘s Lisa Lerer today:

The only regrets we have is that we maybe have not always used the right language. We don’t have regrets about our position and we don’t intend to change it.

Donohue blamed the resignations on an “orchestrated pressure campaign” by environmental groups. He also said:

What we decided to do is we’re going to let the scientists argue the science.

Of course, the scientists aren’t actually arguing anything. The vast majority of scientists long ago determined that climate change is real, and is a really big threat to us all. But it is generous of Donohue to cede the world of science to the scientists, I suppose.

On a related note, Environmental Defense Action Fund has decided to join the ranks of the vast green-wing conspiracy that Donohue blames for his problems. Check out these new ads that we’re running with our friends at NRDC.

Donohue would no doubt see this as part of an “orchestrated pressure campaign.” But much as we’d like to take credit for making five huge corporations leave an organization whose goal is to re-enact one of the most infamous trials in history — as the losing party, no less — we do have to point out that our ads are brand new, so those corporations quit the board all by themselves.

The U.S. Chamber of Commerce continues to make a monkey of itself over its “Scopes trial” comment, as well as its general policy on climate change.

The latest chapter in the ongoing saga comes from high-tech powerhouse Apple, which announced that it is resigning from the Chamber effective immediately. Apple says it objects to “the chamber’s recent comments opposing the E.P.A.’s effort to limit greenhouse gases.” Those comments include threatening litigation.

In a letter to chamber president Thomas Donahue, Apple wrote:

Apple supports regulating greenhouse gas emissions, and it is frustrating to find the chamber at odds with us in this effort.

You can read Apple’s entire letter [PDF] here.

But the bad news for the Chamber doesn’t end there. One of its chapters is now distancing itself from the national organization. That item comes from the San Jose Mercury News editorial “U.S. chamber is a dinosaur on climate change“.

The paper says the San Jose Silicon Valley Chamber of Commerce has “had discussions with the U.S. Chamber and the California Chamber as well as PG&E and several other members.”

The president of the San Jose Silicon Valley chapter solidly opposed her national counterpart’s comments, saying:

There isn’t anyone who doesn’t realize that climate change is a man-made phenomenon and something we need to address and address quickly.

PG& E, of course, has already resigned from the chamber because of its climate policy — as have PNM Resources and Excelon (and now Apple).

Nike withdrew from the Chamber’s board of directors, but hasn’t given up its membership altogether.
