Some 567 local officials from all 50 states — including the mayors of Chicago, Denver, San Francisco, and Washington, D.C. — are calling on the federal government to act more aggressively to combat climate change, in a statement to be released today. As of late last week, enviros had been saying they’d scored a coup by getting New York City Mayor Rudolph Giuliani (R) to sign the statement. But Rudy bailed on Friday night. Yesterday, Pres. Clinton praised the call from local officials. At the same time, Clinton criticized Congress for cutting funds for a clean air program and adding measures to spending bills that he said would “strangle” government efforts to save energy, cut fuel costs for citizens and businesses, and reduce the pollution that causes global warming.
