Heatwaves in Europe, China and America could not have occurred without climate change: study
The HinduThe fingerprints of climate change are all over the intense heat waves gripping the globe this month, a new study finds. “Had there been no climate change, such an event would almost never have occurred,” said study lead author Mariam Zachariah, a climate scientist at Imperial College of London. Since the advent of industrial-scale burning, the world has warmed 2.2 degrees Fahrenheit, so “they are not rare in today’s climate and the role of climate change is absolutely overwhelming,” said Imperial College climate scientist Friederike Otto, who leads the team of volunteer international scientists at World Weather Attribution who do these studies. Phoenix has had a record-shattering 25 straight days of temperatures at or above 110 degrees Fahrenheit and more than a week when the nighttime temperature never dropped below 90 degrees Fahrenheit The heat in Spain, Italy, Greece and some Balkan states is likely to reoccur every decade in the current climate, the study said. The way scientists do these rapid analyses is by comparing observations of current weather in the three regions to repeated computer simulations of “a world that might have been without climate change,” said study co-author Izidine Pinto, a climate scientist at the Royal Netherlands Meteorological Institute.
