Need more proof that Bush will never, ever, in a million gazillion years, sign a decent climate bill? Here’s what his right-hand hack Jim Connaughton had to say ($ub. req’d) about the relatively tepid Lieberman-Warner bill:

James Connaughton, the chairman of the White House Council on Environmental Quality, cited EPA’s worst-case modeling projections for the bill from Sens. Joe Lieberman (I-Conn.) and John Warner (R-Va.).

“We have significant concerns with the current proposals,” Connaughton said in a telephone interview.

Under any new climate law, EPA acknowledged that gross domestic product should double over the next several decades from its current $13.8 trillion, but the EPA results released Friday also show the Lieberman-Warner bill cutting into that GDP growth.

Grist thanks its sponsors. Become one.

EPA models also yielded projections with less of an economic sting, but Connaughton focused on the EPA findings’ high-end costs, which show GDP falling by as much as 3.8 percent, or $983 billion, in 2030 and by up to 6.9 percent, almost $2.9 trillion, in 2050.

Advance scaremongering — expect much more of it.
