2/2/2021 — As we all know, it’s not unusual for the rainy season to start out relatively, well, un-rainy, and then for the state to get hit with a big storm — though not quite like this one. “This storm definitely has more water in it because of climate change,” explained Michael Wehner, a senior scientist who studies extreme weather events and their relationship to climate change at the Lawrence Berkeley National Lab. According to research from Wehner, climate change is driving processes that make winter storms drop more precipitation than has historically been the case in NorCal.
