Climate Models Have Been Estimating Rainfall Incorrectly This Whole Time

Most global climate models are underestimating increased rainfall caused by global warming, according to a study released Monday.

NASA and four universities compared climate data from 1995 to 2005 to 23 climate model simulations for the same period. More than 70 percent of the climate models underestimated the amount of rain compared to the real world observations.

“Precipitation is vital to life on Earth and regional precipitation changes accompanying anticipated global warming could exert profound impacts on ecosystems and human society,” reads the study’s abstract, adding that “we infer that most CMIP5 models underestimate the hydrological sensitivity under global warming.”
