A UCLA study shows that abnormally heavy rain and snowfall events since as early as the 1980s are intensifying globally due to human-driven climate change, researchers said Tuesday.

“These findings further elevate the urgency of reducing greenhouse gas emissions to prevent even larger impacts down the road,” said senior author Alex Hall, director of the UCLA Center for Climate Science, which is a part of the UCLA Institute of the Environment and Sustainability. “We can now say that extreme precipitation is increasing globally due to human-induced climate change.”
