Extinctions related to climate change have already happened in hundreds of plant and animal species around the world. New research, shows that local extinctions have already occurred in 47% of the 976 plant and animal species studied according to Science daily.
Climate change is predicted to threaten many species with extinction, but determining how species will respond in the future is difficult. Dozens of studies have already demonstrated that species are shifting their geographic ranges over time as the climate warms, towards cooler habitats at higher elevations and latitudes. The new study, by Professor John J. Wiens, used these range-shift studies to show that local extinctions have already happened in the warmest parts of the ranges of more than 450 plant and animal species.
