Rainfall from Hurricane Harvey, which struck Houston over the summer, was at least 15% heavier due to human caused climate change, according to two independent studies by researchers at the Lawrence Berkeley National Laboratory and Royal Netherlands Meteorological Institute. Hurricanes like Harvey are also three times more likely today than in 1900, researchers reported.

Why it matters: This isn't the first time scientists have attributed violent weather events to a warming planet, The Washington Post reports. Scientists have also warned of the increased likelihood of droughts such as the one in Texas in 2010 and floods similar to Colorado's in 2013. These findings suggest cities and communities may need to reassess their risk and find new ways to prepare for harsher weather as climate change continues.
