In particular, at 3.2 °C (5.8 °F), 15% of invertebrates (including 12% of pollinators), 11% of amphibians and 10% of flowering plants would be at a very high risk of extinction, while ~49% of insects, 44% of plants, and 26% of vertebrates would be at a high risk of extinction.
Extinction risk: The probability of human extinction within a given timeframe. Extinction threat: A plausible and significant contributor to total extinction risk. Societal fragility: The potential for smaller damages to spiral into global catastrophic or extinction risk due to societal vulnerabilities, risk cascades, and maladaptive responses.
[109] [110] [111] A 1997 assessment states that over a third of Earth's land has been modified by humans, that atmospheric carbon dioxide has increased around 30 percent, that humans are the dominant source of nitrogen fixation, that humans control most of the Earth's accessible surface fresh water, and that species extinction rates may be over ...

Climate endgame is a term used to refer to the risk of societal collapse and potential human extinction due to the effects of climate change. [2] The usage of the term seeks to improve risk management by putting a higher priority on worst-case scenarios, to "galvanise action, improve resilience, and inform policy".
As the result, the study estimated the risk of an abrupt cooling event over Europe caused by the collapse of the current at 36.4%, which is lower than the 45.5% chance estimated by the previous generation of models [81] In 2022, a paper suggested that previous disruption of subpolar gyre was connected to the Little Ice Age.
