摘要

Limiting 氣候 change to less than 2°C is the focus of international policy under the 氣候 convention (UNFCCC), and is essential to preventing extinctions, a focus of the Convention on 生物 多樣性 (CBD). The post-2020 生物多樣性 framework drafted by the CBD proposes conserving 30% of both land and oceans by 2030. However, the combined impact on extinction risk of 物種 from limiting 氣候 change and increasing the extent of protected and conserved areas has not been assessed. Here we create conservation spatial plans to minimize extinction risk in the tropics using data on 289 219 物種 and modeling two future greenhouse gas concentration pathways (RCP2.6 and 8.5) while varying the extent of terrestrial protected land and conserved areas from <17% to 50%. We find that limiting 氣候 change to 2°C and conserving 30%
