Utility group to Waxman: We don't doubt climate science

APPA "does not dispute the science of climate change, which has shown that: 1) climatic changes are occuring; and 2) human actions are contributing to such changes," states a March 3 letter from the group to Waxman and Markey.

The group opposes EPA regulation of greenhouse gases from stationary sources under its current Clean Air Act powers, but believes Congress should enact "appropriate" climate legislation.

Murkowski said that's why she's pushing the measure too -- she fears the economic effects of planned emissions rules. Her resolution may come to the floor this month.

But Waxman, Markey and other opponents of Murkowski's plan are casting it as an attack on climate science rather than just a procedural maneuver to stymie regulations. Sen.
