How Are Jackson Hole Temperatures Changing?

Shuman, Bryan

Abstract

Jackson Hole’s climate has been changing. NASA reports that global average temperatures in 2023 were 1.8°F (1.0° C) higher than the average from 1950-1981, but local changes are not always the same as global averages. Jackson Hole is unique. Our weather has tracked the global trends in surprising ways that is already affecting this iconic landscape. The Nature Conservancy’s Wildflower Watch, building on the pioneering observations of Frank Craighead, has found that flowers in Jackson Hole are blooming three weeks earlier now than in the 1970s. Our weather stations help to show why.
