Report: Global Warming Has Changed Our Weather — Worse Heat Waves, Floods, Hurricanes, Storms To Come

Today, the federal government has released a report that assembles this knowledge in stark and unequivocal terms. “Weather and Climate Extremes in a Changing Climate,” by the multi-agency U.S. Climate Change Science Program with the National Oceanic and Atmospheric Administration in the lead, warns that changes in extreme weather are “among the most serious challenges to society” in dealing with global warming. After reporting that heat waves, severe rainfall, and intense hurricanes have been on the rise — all linked to manmade global warming — the authors deliver this warning about the future:

In the future, with continued global warming, heat waves and heavy downpours are very likely to further increase in frequency and intensity. Substantial areas of North America are likely to have more frequent droughts of greater severity. Hurricane wind speeds, rainfall intensity, and storm surge levels are likely to increase. The strongest cold season storms are likely to become more frequent, with stronger winds and more extreme wave heights.
