Climate change's fingerprints are on U.S. Midwest floods: scientists

The "bomb cyclone" that dumped rain on Nebraska, Iowa and Missouri and killed at least four people now threatens a wider region downstream of swollen rivers and smashed levees. "The atmosphere is pretty close to fully saturated, it's got all the water it can take," said Michael Wehner, a senior scientist at the Lawrence Berkeley National Laboratory. Big storms like the bomb cyclone and Hurricane Harvey, which smacked Houston in 2017 with record downpours, are where the impact of climate change can most clearly be seen, he said, adding that climate change's fingerprints were all over the recent storm.
