Figure S6 indicates the projected changes in species richness globally at the four levels of warming (1.5°, 2°, 3.2°, 4.5°C above pre-industrial levels) and, where appropriate, (for animals) including or excluding realistic dispersal.

We find substantial benefits to limiting warming to 1.5°C above preindustrial levels as compared with 2°C by 2100. The number of insect species projected to lose >50% of their range is reduced by about 66%, whereas the number of plant and animal species projected to lose more than half their range is reduced by ~50%.
