Chunks of ice float on Mendenhall Lake in front of the Mendenhall Glacier on Monday, May 30, 2022, in Juneau, Alaska. A study of all of the world's 215,000 glaciers published on Thursday, Jan. 5, 2023, finds even if with the unlikely minimum warming of only a few tenths of a degrees more, the world will lose nearly half its glaciers by the end of the century. With the warming we're now on track to get, the world will lose two-thirds of its glaciers and overall glacier mass will drop by one-third while sea level rises 4.5 inches just from melting glaciers.
