The recent accecptance by a wide cross section of the thinking population that greenhouse warming is a real phenomenon isn't enough to shift government action in a useful direction. Indeed the present U.S. Government approach is to hide evidence or scientific studies that tend to support the idea that global warming is real. The EPA has been hijacked by some folks who don't value the environment, and the quality of their science has declined in direct porportion to the degree of politization of the budget allocation process. Science is subject to doctrinare censorship in a number of government sponsored arenas, since the Bush administration overcame the opposition. Even studies on things that might be beneficial to mankind are subject to the political litmus test by the NeoCons.
