Studying the association between Earth climate and extinctions over the past 520 million years, scientists from the University of York write, "The global temperatures predicted for the coming centuries may trigger a new 'mass extinction event', where over 50 percent of animal and plant species would be wiped out."[1]

The IPCC Sixth Assessment Report (2021) projects progressively large increases in both the frequency (horizontal bars) and intensity (vertical bars) of extreme weather events, for increasing degrees of global warming.

  • Terrestrial ecosystems and biodiversity: With a warming of 4-5 °C, relative to 2010 levels, it is likely that global terrestrial vegetation would become a net source of carbon (Schneider et al., 2007:792). With high confidence, Schneider et al. (2007:788) concluded that a global mean temperature increase of around 4 °C (above the 2010–2015) by 2100 would lead to major extinctions around the world.
  • Marine ecosystems and biodiversity: With high confidence, scientists concluded that a warming of 2-3 °C above 2010 levels would result in mass mortality of coral reefs globally. In addition, several studies dealing with planktonic organisms and modelling have shown that temperature plays a transcendental role in marine microbial food webs, which may have a deep influence on the biological carbon pump of marine planktonic pelagic and mesopelagic ecosystems.[3][4][5]
  • Freshwater ecosystems: Above about a 4 °C increase in global mean temperature by 2100 (relative to 2010), scientists concluded, with high confidence, that many freshwater species would become extinct or largely endangered.
