From the LA Times:
The Environmental Protection Agency released a historic finding Monday that greenhouse gases are endangering public health and welfare.
We have a different question for the EPA: Why has it taken so long?
Thus began more than a year and a half of foot-dragging by the Bush administration, which had reams of data pointing out the clear dangers of climate change but refused to take action.
The EPA is hardly rushing to judgment by finally obeying the law and acknowledging the overwhelming worldwide consensus that carbon-fueled climate change threatens human health. Global warming is expected to cause deaths related to adverse temperatures ...
The finding by the EPA, which paves the way toward concrete regulatory limits on greenhouse gases, is the most significant action taken by the federal government to date to address the problem.
all eyes are looking to the United States, the world's second-biggest carbon emitter after China (and a far bigger polluter than China on a per capita basis).
If the U.S. refuses to take strong steps, which it has done consistently until now, it's unreasonable to ask or expect any other nation to do so.
