According to a recent study by scientists from Germany’s Potsdam Institute for Climate Impact Research, some newer climate models greatly underestimate the extent to which global heating leads to extreme rainfall.

The study predicts more frequent disastrous flooding unless humans reduce greenhouse gas emissions.

“Extremes appear to intensify faster with global warming than the models predict,” said Anders Levermann, one of the authors of the study and a climate scientist at the Potsdam Institute of Climate Impact Research, as New Scientist reported. “Extreme rainfall will be heavier and more frequent. Society needs to be prepared for this.”

The researchers examined the frequency and intensity of daily land-based precipitation extremes in 21 climate models classified as “next generation” that were used by a United Nations body to conduct global assessments, reported AFP.

The research team compared historical changes with those predicted by the climate models and found that almost all the models […]
