They have measured this increase in parts of Canada, most of Europe, the U.S. Midwest and Northeast, northern Australia, Western Russia and parts of China.

From 2004 to 2013, worldwide, bouts of extreme rainfall rain increased by 7%. In Europe and Asia, the same decade registered a rise of 8.6% in cascades of heavy rain.

The scientists report in the journal Water Resources Research that they excluded areas where the records were less than complete, but analyzed 8,700 daily rain records from 100,000 stations that monitor rainfall worldwide. They found that from 1964 to 2013, the frequency of catastrophic downpours increased with each decade.

“By introducing a new approach to analyzing extremes, using thousands of rain records, we reveal a clear increase in the frequency of extreme rain events over the recent fifty […]
