The battle cry of Joseph Romm at Climate Progress (Center for American Progress) earlier this year was “Obama Can Get a Better Climate Bill in 2010: Here’s How.” But now Romm is in panic mode, trying to convince the rebelling Environmental Left that the out-of-control Waxman-Markey climate change bill (now 1,090 1,201 pages) is the last best hope to save civilization. As Romm stated in a post yesterday:

Waxman-Markey is the only game in town.  If it fails, I see no chance whatsoever of stabilizing anywhere near 350 to 450 ppm since serious U.S. action would certainly be off the table for years, the effort to jumpstart the clean energy economy in this country would stall, the international negotiating process would fall apart, and any chance of a deal with China would be dead.

I have previously described Exxon Mobil as the anti-Enron. In an opinion-page editorial in yesterday’s Houston Chronicle, I contrasted the two companies in terms of both energy strategy and public policy.

More could be said than is in the editorial (reprinted below). Enron’s first fraud, engineered by Andrew Fastow, came with the purchase of Zond Corporation, which was renamed Enron Wind Corporation and is now part of GE Energy. (This complicated story about a “qualifying facility” under federal energy law is told in McLean and Elkind’s The Smartest Guys in the Room, pp. 166–67 and Kurt Eichenwald’s Conspiracy of Fools, pp. 142–44.)

Enron Energy Services, the energy outsourcing division of Enron that so excited environmentalists (including Joe Romm, now blogging at Climate Progress), was one of the company’s biggest frauds.…

Chip Knappenberger was perhaps the first analyst to demonstrate the negligible impact on global temperatures that would result from unilateral U.S. adoption of the pending Waxman-Markey bill. Knappenberger showed that even if the U.S. cut its emissions by 83% (of the 2005 level) by the year 2050, and then capped them at that level indefinitely, the schedule of global temperature increases would only be postponed by about five years.

Naturally, supporters of strong government action argued that the whole point of Waxman-Markey was to give American negotiators credibility when they demanded reciprocal action from other countries; Paul Krugman says as much in a recent blog post. Yet this leads to the next major problem: If the whole world adopted the stringent emission cutbacks in Waxman-Markey, then the costs to the global economy would far outweigh any reasonable estimate of the benefits (measured in avoided climate damage).…

In a provocative post, Joe Romm argues that even “strong climate action” would be well worth the effort. Yet Romm’s claim that stabilizing atmospheric greenhouse gases at 445–535 ppm (CO₂-eq) would cost only “one tenth of a penny on the dollar” (through 2050) understates the IPCC’s actual cost estimate by about 95%. In reality, the IPCC’s reported estimate translates into a mitigation cost of about 2.2 cents on the dollar–far far higher than Romm’s figure. Romm’s mistake has nothing to do with climate science: he simply confuses the rate of growth in income, with income itself.

To make matters worse, even when correctly interpreted, the IPCC estimate significantly understates what the cost will be in practice. The IPCC admits that its estimate is a theoretical textbook case, which assumes all participating countries implement their mitigation policies perfectly, and keep them in force throughout the 21st century.…
