News today:

Climate change will pose "substantial" threats to human health in the coming decades, the Environmental Protection Agency said yesterday — issuing its warnings about heat waves, hurricanes and pathogens just days after the agency declined to regulate the pollutants blamed for warming.

That’s reassuring, coming from the federal government.  Unfortunately, the EPA was saying something else only last week:

In a 588-page federal notice, the Environmental Protection Agency made no finding on whether global warming poses a threat to people’s health, reversing an earlier conclusion at the insistence of the White House and officially kicking any decision on a solution to the next president and Congress.

The bottom line, I think, is that the EPA does believe that global change does threaten human health, but they aren’t going to do anything until Bush gets out of office.
