Study finds that climate change added 10% to Ian’s rainfall

A quick study by two scientists calculates that climate change made Hurricane Ian 10% rainier than it would have been if there were no such thing as global warming. Thursday’s analysis, which was not peer reviewed, is based on 20 computer simulations of a world with no climate change from the burning of coal, oil and natural gas. Scientists then compared those scenarios to what was playing out in real time with Hurricane Ian. The authors compared the highest rainfall rates over three hours.
