Such dangerous feedback loops are conjectured but not actually a threat. It can be proven with historical evidence like this paper, which shows that during the Roman times it must have been much hotter than today, like somewhere between 3-7 degrees hotter, based on the discovery of bison fossils in the Alps. This is well beyond the level climatologists claim would cause runaway feedback driven global warming and mass extinction, yet that didn't happen. The historical records don't contain any reference to climate meltdowns around that time, and humanity obviously wasn't wiped out by anything. http://www.museumgolling.at/wp-content/uploads/2022/09/9_Schaer_Wisent_published.pdf http://www.museumgolling.at/wp-content/uploads/2022/09/9_Sch... These wisent remains from alpine caves are all from sites now in the subalpine to alpine zone. From this it can be concluded that the beech limit but also the forest line during the »wisent time« (6,000 to 1,200 years before today) was much higher and the average summer temperature had to be at least 3 to 6 °C higher than today Oaks (Quercus) at an altitude of 1,450 metres around 2,000 years ago also indicate a climate approximately 4 to 7 °C warmer than today There's a lot of evidence pointing in the same direction. https://www.nature.com/articles/s41598-020-67281-2 https://www.nature.com/articles/s41598-020-67281-2 This record comparison consistently shows the Roman as the warmest period of the last 2 kyr, about 2 °C warmer than average values for the late centuries for the Sicily and Western Mediterranean regions. Yet according to scientists, "Temperature rises over 2 degrees could bring catastrophic and potentially irreversible impacts, including pushing three billion people into chronic water scarcity." https://edition.cnn.com/2023/01/30/world/global-warming-critical-threshold-climate-intl/index.html https://edition.cnn.com/2023/01/30/world/global-warming-crit...
