TS.B.1.3 At the warm  edges of distributions, adaptation limits to human-induced warming have led to widespread local population losses  that result in range contractions . Among land plants and animals, local population loss was detected in around 50% of studied species and is often attributable to extreme events . Such extirpations are most common in tropical habitats  and freshwater systems , but also high in marine  and terrestrial  habitats. Many mountain-top species have suffered population losses along lower elevations, leaving them increasingly restricted to a smaller area and at higher risk of extinction . Global extinctions due to climate change are already being observed, with two extinctions currently attributed to anthropogenic climate change . Climate-induced extinctions, including mass extinctions, are common in the palaeo record, underlining the potential of climate change to have catastrophic impacts on species and ecosystems .
