The panel said the world needs to get ready for more dangerous and "unprecedented extreme weather" caused by global warming. These experts fear that without preparedness, crazy weather extremes may overwhelm some locations, making some places unlivable.
The Nobel Prize-winning Intergovernmental Panel on Climate Change issued a special report on global warming and extreme weather Friday after meeting in Kampala, Uganda. This is the first time the group of scientists has focused on the dangers of extreme weather events such as heat waves, floods, droughts and storms. Those are more dangerous than gradual increases in the world's average temperature.
For example, the report predicts that heat waves that are now once-in-a-generation events will become hotter and happen once every five years by mid-century and every other year by the end of the century. And in some places, such as most of Latin America, Africa and a good chunk of Asia, they will likely become yearly bakings.
And the very heavy rainstorms that usually happen once every 20 years will happen far more frequently, the report said. In most areas of the U.S. and Canada, they are likely to occur three times as often by the turn of the century, if fossil fuel use continues at current levels. In Southeast Asia, where flooding has been dramatic, it is likely to happen about four times as often as now, the report predicts.
