So President Obama has thrown some crumbs to his supporters in the NGOs by giving a speech on climate (coverage here, for example). I'm not sure there's much to genuinely quicken the pulse here. The general theme seems to be some more fixing of markets to favour his supporters in the renewables industry and some more regulations to tie up the fossil fuel bogeyman.
It's just that it's only coal he intends to tie up in red tape; several commentators are noting that he almost seems to be smooching up to the fracking industry. So one could almost see this as "going with the flow" rather than an attempt to change anything.
Meanwhile, there are no carbon taxes or emissions pricing mechanisms on offer and none of the more suicidal actions longed for by environmentalists and other eccentrics. It seems like something of a damp squib, given the excited trailing of the speech beforehand.
And in fact, the sudden interest in climate is odd in itself. So late in his tenure, it's hard to see him as being able to achieve anything very much. Anyone would think he was trying to divert attention from his problems on the civil liberties front.
