Since the AR5 , global meta-analyses found at least 15  and 25  additional sites, respectively, of drought-induced tree mortality around the world. These and other global analyses found more rapid mortality than previously , rising background mortality , mortality increasing with drought severity , mortality of tropical trees increasing with temperature , mortality increasing with tree size for many species , mortality predominantly at the dry edge of species ranges  and three-quarters of drought-induced mortality cases leading to a change in the dominant species . Multiple non-climate factors contribute to tree mortality, including timber cutting, livestock grazing and air pollution . Globally, tropical dry forests lost, from all causes, 95,000 km2, 8% of their total area, from 1982 to 2016, the most extensive area of mortality of any biome .
