Some YDIH proponents have also proposed that this event triggered extensive biomass burning, a brief impact winter that destabilized the Atlantic Conveyor and triggered the Younger Dryas instance of abrupt climate change [8]: p. 16021 which contributed to extinctions of late Pleistocene megafauna, and resulted in the disappearance of the Clovis ...
The vulnerability of different European lizard populations to extinctions caused by climate change. Populations in group A are already at risk; B and C will be threatened under 2 °C (3.6 °F). Groups D and E will become threatened under 3 °C (5.4 °F) and 4 °C (7.2 °F), and Group F is unikely to be threatened. [93]
Correlations between times of first appearance of humans and unique megafaunal extinction pulses on different land masses Cyclical pattern of global climate change over the last 450,000 years (based on Antarctic temperatures and global ice volume), showing that there were no unique climatic events that would account for any of the megafaunal ...
The study, however, found an apparently low extinction rate in the fossil record of mainland Asia. [141] [142] A 2020 study published in Science Advances found that human population size and/or specific human activities, not climate change, caused rapidly rising global mammal extinction rates during the past 126,000 years. Around 96% of all ...
As part of a team, he also found that climate change is shifting the human climate niche at an unprecedented rate, with potentially devastating consequences for the poorest regions of the world, [47] and that it could push one-third of humanity outside the human climate niche by end-of-century under current policies, but reducing warming to 1.5 ...
An ancient species of great ape was likely driven to extinction hundreds of thousands of years ago when climate change put their favorite fruits out of reach during dry seasons, scientists ...
End-Capitanian extinction event: 260 Ma: Volcanism from the Emeishan Traps, [28] resulting in global cooling and other effects Olson's Extinction: 270 Ma Unknown. [29] [30] [31] Possibly a change in climate, but evidence for this is weak. [32] This event may actually be a slow decline over 20 Ma. [33] Carboniferous: Carboniferous rainforest ...
Instead, it argues that vice versa the declining megafauna was the precondition for the vegetational turnover, and that healthy megafauna populations could have maintained their preferred environment, the mammoth steppe, even under the stresses of the warming climate if human-induced extinctions had not occurred.
