New Delhi, April 25 -- Large areas of wildlife habitat worldwide are likely to be hit by multiple extreme weather events by 2050, according to a new paper in Nature Ecology and Evolution - with the scale of impact determined, in large part, by how quickly the world cuts emissions. Using climate impact projections and species range data, scientists modelled changes in exposure to droughts, heatwaves, river floods and wildfires for 33,936 terrestrial vertebrate species across 794 ecoregions. By 2050, under a medium-high emissions scenario, an average 74% of the area within species' current geographic ranges is projected to be exposed to heatwaves, 16% to wildfires, 8% to droughts and 3% to river floods. Species-rich areas in the Amazon basin,...
