Global warming made Hurricane Harvey deadly rains three times more likely, research reveals

The unprecedented downpour and severe flooding was also 15% more intense due to climate change, which is making weather more violent around the world

Hurricane Harvey's unprecedented deluge, which caused catastrophic flooding in Houston in August, was made three times more likely by climate change, new research has found.

Such a downpour was a very rare event, scientists said, but global warming meant it was 15% more intense. The storm left 80 people dead and 800,000 in need of assistance.
