Climate Change Panel Says Expect More Extreme Weather

Over the last half-century, global warming has led to changes in climate extremes such as heat waves, record high temperatures and in many regions, heavy precipitation. That’s the conclusion of a new report by the Intergovernmental Panel on Climate Change. The group, founded by the United Nations in 1988, warns that nations across the globe must take steps to mitigate such disaster.

Extreme weather cut a swath across the world in 2011. For Bill Wing, it began a year ago on New Year’s Day as he surveyed the damage from a tornado that touched down in Cincinnati, Arkansas.
