The authors based their findings on the current trajectory of global warming, which is on pace to increase global temperatures by 3.2 degrees Celsiuscompared to pre-industrial levels.
They looked at 31,000 insect species, 8,000 bird species, 1,700 mammal species, 1,800 reptile species, 1,000 amphibian species, and 71,000 species of plants, according to Quartz, and found consistent geographical declines across the animal kingdom.
Insects fared worst in this analysis, with 50% of species losing more than half of their overall ranges if temperatures increased by 3.2 degrees celsius.
An estimated 44% of plants would lose half their overall range, compared to 26% of mammals, birds, reptiles, amphibians, and fish facing the same decline.
