The nation is headed for strong heat waves in coming decades that will hit cities and farmers and threaten wildlife with extinction, a new global warming report warns. The report, "More Extreme Heat Waves: Global Warming's Wake Up Call," sponsored by medical, environmental and civil rights organizations, comes as a legislative fight over a climate change bill gets ready to resume next month in Congress. Its remedies are based on recent findings of global warming effects by the U.S. Global Change Research Program, which coordinates climate research across federal agencies. "The report highlights the current vulnerabilities from heat waves growing," says climate scientist Amanda Staudt of the National Wildlife Federation, a report sponsor. Average temperatures are expected to grow 4 to 11 degrees Fahrenheit nationwide over the next century, according to the federal climate research group.
