Present-day greenhouse gases could cause more frequent and longer Dust Bowl heatwaves

Nature Climate Change, Published online: 18 May 2020; doi:10.1038/s41558-020-0771-7 The United States experienced two of its hottest recorded summers in 1934 and 1936, amplified by drier soils associated with the Dust Bowl drought. A large regional climate model ensemble estimates present-day GHGs would cause similarly extreme, 1-in-100-year heatwaves to occur about every 40 years.
