The article above suggests that Obama might speak about global warming, but, DUH, nothing will get done with a GOP House and the crappy assumptions people have about things like a carbon tax.
The thing is, Obama has taken action on global warming that's sometimes hard to see as action. There was a major weather-proofing initiative as part of the stimulus. There have been a host of other small bore conservation efforts. There have stimulative measures for solar and wind power.
In short, Obama has approached global warming the same way he approached health care reform: "What can I get done?" The result is a whole lot more than nothing and a whole lot less than what is needed in the eyes especially of progressives.
Whether this is Obama's fault or the fault of the American political system is an open question.
