Cli­mate re­port: A mas­sive fed­eral gov­ern­ment study re­leased last week con­cludes that hu­mans are the “dom­i­nant cause” of global cli­mate change, and that heavy rains, heat waves, and for­est fires are ex­pected to be­come more fre­quent in the U.S. if green­house gas emis­sions are not curbed. There is “no con­vinc­ing al­ter­na­tive ex­pla­na­tion” for global warm­ing out­side of hu­man ac­tiv­ity, the study says, con­tra­dict­ing state­ments by Pres­i­dent Trump. The re­port, pro­duced by sci­en­tists from 13 fed­eral agen­cies, says that av­er­age global tem­per­a­tures have in­creased 1.8 de­grees over the past 115 years, an “un­am­bigu­ous” warm­ing trend caused by emis­sions, and that sea lev­els have risen by 7 inches over the same pe­riod. The White House has worked to down­play dis­cus­sions of cli­mate change, which Trump has called an “ex­pen­sive hoax.” But gov­ern­ment sci­en­tists say the re­port has met with lit­tle of­fi­cial push­back.
