 Projected biodiversity loss, quantified as percentage change in species abundance, range size or area of suitable habitat increases with increasing global warming levels . Above 1.5°C global warming, half of all assessed species are projected to lose >30% of their population, range size or area of suitable habitat, with losses increasing to >40% for >2°C. The 2001-2020 level of global warming is around 1ºC higher than 1850-1900 . Boxplots show the median , 50% quantiles , and points are studies of individual species or of multiple species .
