This was compared against climate reconstructions for the last 90,000 years. The researchers found correlations of human spread and species extinction indicating that the human impact was the main cause of the extinction, while climate change exacerbated the frequency of extinctions. The study, however, found an apparently low extinction rate ...
Christopher Walter Monckton, 3rd Viscount Monckton of Brenchley (born 14 February 1952) is a British public speaker and hereditary peer.He is known for his work as a journalist, Conservative political advisor, UKIP political candidate, and for his invention of the mathematical puzzle Eternity.
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 ...
A marsupial lion skeleton in the Naracoorte Caves, South Australia. The term Australian megafauna refers to the megafauna in Australia [1] during the Pleistocene Epoch.Most of these species became extinct during the latter half of the Pleistocene, and the roles of human and climatic factors in their extinction are contested.
Two main theories propose a cause for megafauna extinction - human impact and changing climate. A study has been performed in which more than 700 Genyornis eggshell fragments were dated. [9] Through this, it was determined that Genyornis declined and became extinct over a short period—too short for it to be plausibly explained by climate ...
Another study examined the change in the methane concentration in the atmosphere at the end of the Pleistocene epoch after the extinction of megafauna in the Americas. After early humans migrated to the Americas about 13,000 BP, their hunting and other associated ecological impacts led to the extinction of many megafaunal species there ...

Pleistocene rewilding is the advocacy of the reintroduction of extant Pleistocene megafauna, or the close ecological equivalents of extinct megafauna. [1] It is an extension of the conservation practice of rewilding , which aims to restore functioning, self-sustaining ecosystems through practices that may include species reintroductions.
