Climate Change Fingerprints On July Heat Around The Globe, Study Says

"The fingerprints of climate change are all over the intense heat waves gripping the globe this month, a new study finds. Researchers say the deadly hot spells in the American Southwest and Southern Europe could not have happened without the continuing buildup of warming gases in the air.

Thanks to years of research and more powerful computers, scientists can now determine almost in real-time whether climate change is contributing to the intensity of heat, storms, floods and drought — and by how much.

A generation ago, calculating such connections took up to a year, but researchers at World Weather Attribution made their conclusions about this summer’s heat wave in less than a week. Their study is the first to look at three simultaneous heat waves on three different continents."
