Sins of Emission
The ethanol boondoggle is also an environmental catastrophe.
OCTOBER 29, 2009.

Donning FDR's cape, Eisenhower's stripes and JFK's boat shoes, President Obama observed in Florida on Tuesday that his "clean energy economy" will require "mobilization" on the order of fighting World War II, building the interstate highway system and going to the moon. Of course, the only "mobilization" going on at the moment is on behalf of ethanol, whose many political dispensations the biofuels lobby is finding new ways to preserve even as the evidence of its destructiveness piles up.

The latest embarrassment arrives via the peer-reviewed journal Science, not known for its right-wing inclinations. A new paper calls attention to what the authors (led by Princeton's Tim Searchinger) call "a critical accounting error" in the way carbon emissions from biofuels are measured in climate-change programs world-wide. Bernie Madoff had a few critical accounting errors too.

Though you won't hear it from the biofuels lobby, ethanol actually generates the same amount of greenhouse gas as fossil fuels, or more, per unit of energy. But this was still supposed to be better than coal or oil because ethanol's CO2 is "recycled." Since plants absorb and store carbon that is already in the atmosphere, burning them as fuel would create no new emissions, whereas fossil fuels release CO2 that has been buried for millions of years.

With everything supposedly balancing out, the cap-and-trade programs run by the United Nations and European Union—and maybe soon the U.S.—treat biofuels as carbon-neutral. The Science study argues that this is a false economy, because it doesn't consider changes in land use. If mature forests are cleared to make room for biofuel-growing farms, then the carbon that would otherwise accumulate in those forests ought to be counted on ethanol's balance sheet as well.

Cap-and-trade programs exacerbate the problem because developed countries (where emissions are putatively capped) get credit for reductions from ethanol—despite the fact that their biofuels are generally grown in developing countries (where emissions aren't capped). So if Malaysians burn down a rain forest to grow palm oil that ends up in German biodiesel, Malaysia doesn't count the land-use emissions and Germany doesn't count the tail-pipe emissions.

Given these incentives, the authors cite a study showing that by 2050, "based solely on economic considerations, bioenergy could displace 59% of the world's natural forest cover. . . . The reason: When bioenergy from any biomass is counted as carbon neutral, economics favor large-scale land conversion for bioenergy regardless of the actual net emissions." In other words, not only is cap and trade self-defeating on its own terms but it also risks creating a genuine ecological disaster.

By way of a solution, Mr. Searchinger and his coauthors modestly suggest doing away with the regulatory three-card monte and counting net ethanol emissions from where they are actually emitted. But this is political heresy on Rep. Henry Waxman's Energy and Commerce Committee, which passed its own cap-and-tax program in July with the votes of farm-state Democrats, because the bill all but banned the Environmental Protection Agency from studying land-use changes. So much for letting "the science" guide public policy.

In Florida, Mr. Obama said the only people who could oppose his climate plan are "those who are afraid of the future." On this one, at least, the President is right.

The Economic Uses of Al Gore
Sincerity is no substitute for disinterestedness.
By HOLMAN W. JENKINS, JR.
NOVEMBER 10, 2009, 8:56 P.M. ET.

Last spring Tennessee Republican Rep. Marsha Blackburn asked Al Gore during a House hearing if his investments in green energy meant he would benefit personally from cap and trade.

"If you believe that the reason I have been working on this issue for 30 years is because of greed, you don't know me," Mr. Gore responded (and, yes, according to two reporters present, he sighed).

Mr. Gore is quite right that his arguments should be judged on their merits, not on his investments. He's wrong to think his investments are irrelevant, and, even more, that sincerity is dispositive of anything. Sincerity is no substitute for disinterestedness.

Here are a couple questions: When so much of his position and prestige are invested in a predicted climate crisis, is Mr. Gore likely to be open to contrary evidence? Is he likely to be particularly fastidious about whether proposed steps will actually have an effect on global warming if they also happen to benefit his investments?

Ms. Blackburn's challenge was in a sense late. Mr. Gore long ago jumped over to the side where salesmanship, by whatever means, was the trumping priority. As far back as 1989, he insisted there was "no dispute worthy of recognition" about the danger of manmade climate change. By now, he titularly heads a vast establishment with a stake in one side of the argument.

Notice, for instance, after a decade in which the earth appears to have stopped warming and even cooled, that global warming advocates have rushed to embrace a computer simulation that predicts this cooling (in retrospect, of course) and allows for indefinite future cooling, even while assuring that the world is destined to face disastrous warming anyway. Isn't this what forecasters of doom have done since time immemorial when their deadlines for doom haven't been met?

Mr. Gore's own predictions of a climate catastrophe have not lessened, but every time he opens his mouth, the costs of meeting the emergency become easier and easier to swallow. They aren't even costs anymore; as he says in his new book, they are "profits."

All policy salesmanship naturally defaults toward the proposition of huge benefits and negligible costs (i.e., free lunchism). Isn't that where Al Gore is today?

Mr. Gore notes that he has poured his own money into two climate action nonprofits, but, whatever his self-felt motives, aren't these nonprofits functionally propaganda arms (i.e., advertising) that benefit his for-profit investments?

The truth is, evidence of man's impact on climate remains maddeningly elusive, in part because man's impact on climate is so small as to be hard to disentangle from natural variability. This is not Mr. Gore's position, of course. If anything, however, the case for action has become less closed since he pronounced it closed in 1989, if only because of the huge sums and manpower poured into the subject to little avail.

In retrospect, a significant moment was the falling apart or debunking of two key attempts seemingly well-suited to clinch matters for a scientifically literate public. One, the famous hockey stick graph, which suggested the temperature rise of the past 100 years was unprecedentedly steep, was convincingly challenged. The other, a mining of the geological record to show past episodes of warming were sharply coupled with rising CO2 levels, fell victim to a closer look that revealed that past warmings had preceded rather than followed higher CO2 levels.

These episodes from a decade ago testified to one important thing: Even climate activists recognized a need for evidence from the real world. The endless invocation of computer models wasn't cutting it. Yet today the same circles are more dependent than ever on predictions made by models, whose forecasts lie far enough in the future that those who rely on them to make policy prescriptions are in no danger of being held accountable for their reliability.

For a while the media could patch over the scientific shortfall by reporting evidence of warming as if it were evidence of what causes warming. Inconveniently, however, just as temperature-measuring has become more standardized and disciplined and less reliant on flaky records from the past (massaged to the Nth degree), the warming trend seems to have faded from the recent record.

We could go on. But from our first column on this subject, we have been convinced that the scientific questions are interesting and irrelevant, since it was never in the cards that Western societies (or Brazil or India or China) would sacrifice economic growth for the uncertain benefits of fighting climate change. Unable to do anything meaningful about climate change, policy would therefore default to satisfying the demand of organized interests for climate pork.

Isn't that, however much he may be distracted by feelings of sincerity, exactly the economic function of Mr. Gore today?
