Study: Earth’s Killer Heat Will Get Worse

(19 Jun 2017) A new global study says deadly heat waves will grow in area, frequency and intensity, affecting 75 percent of the world's population if greenhouse emissions are not reduced. A team of researchers examined 1,949 deadly heat waves from around the world since 1980 to look for trends, define when heat is so severe it kills and forecast the future. They found that nearly one in three people now experience 20 days a year when the heat reaches deadly levels. But the study predicts that up to three in four people worldwide will endure that kind of heat by the end of the century, if global warming continues unabated. The study comes as much of the U.S. swelters through extended triple-digit heat. Temperatures hit records of 106, 105 and 103 in Santa Rosa, Livermore and San Jose, California on Sunday, as a heat wave was forecast to continue through midweek. Researchers created an interactive global map with past heat waves and computer simulations to determine how much more frequent they will become under different carbon dioxide pollution scenarios. The map shows that under the current pollution projections, the entire eastern United States will have a significant number of killer heat days. Even higher numbers are predicted for the Southeast U.S., much of Central and South America, central Africa, India, Pakistan, much of Asia and Australia. Researchers documented more than 100,000 deaths since 1980, but said there are likely far more because of areas that didn't have good data. Not all of them were caused by man-made climate change. Just one heat wave - in Europe in 2003 - killed more than 70,000 people.
