Mahowald and University of Oklahoma meteorology professor Jason Furtado said updating normal calculations helps city and regional planners to prepare for flooding and drought, farmers to decide what and when to plant, energy companies to meet changing demands and doctors to tackle public health issues arising from climate change.īut Pennsylvania State University climate scientist Michael Mann said he prefers using a constant baseline, such as 1951 to 1980, as NASA does. and others could help cap global warming at 2 degrees Celsius (3.6 degrees Fahrenheit) by century’s end.Ĭlimate scientists are split about how useful or misleading newly calculated normals are. Scientists say recent pledges by the U.S. World & Nation New pledges by U.S., others put Paris climate accord goals in closer reach, scientists say Seattle’s normal is 5% wetter than it used to be. The normal annual rainfall there dropped 10%, to 7.2 inches (18.2 centimeters).Īt the same time, Asheville saw a nearly 9% increase in rainfall, while New York City’s rainfall rose 6%. New normals are warmer because the burning of fossil fuels is making the last decade “a much hotter time period for much of the globe than the decades” before, said Cornell University climate scientist Natalie Mahowald.įor Phoenix, the biggest change in normal came in precipitation. Other large changes were in California, Texas, Virginia, Indiana, Arizona, Oregon, Arkansas, Maryland, Florida, North Carolina and Alaska. 
Seattle, Atlanta, Boston and Phoenix had their normal annual temperature rise by at least half a degree in the last decade.Ĭharlottesville, Va., saw the biggest jump in normal temperatures among 739 major weather stations. In Chicago and Asheville, N.C., the new yearly normal temperature jumped 1.5 degrees in a decade. Global warming pushed temperatures into record territory in 2020, in effect tying 2016 as the hottest year on record, according to new data.
