Computer modelling predicts a permanent change to the climate of the Arctic.
The fast-warming Arctic has started to transition from a predominantly frozen state into an entirely different climate, according to a comprehensive new study of Arctic conditions. https://phys.org/news/2020-09-arctic-transitioning-climate-state.html?fbclid=IwAR0AmPKXCWdmTKJ8SLZGftHj0HYXFuxhe4qr6ihic8-Rh_56g-0W9hXWRrg

Mammal extinctions are now occurring at a rate 1700 times faster than in the pre-human epoch of the Late Pleistocene.
To the innocent eyes of animals, the appearance of humans on the horizon represents more of an existential threat than the vast environmental upheaval of previous climate change up until now, new research suggests. https://www.sciencealert.com/mammal-extinctions-are-speeding-up-with-unprecedented-magnitude-scientists-warn?fbclid=IwAR0E73Y_GivxTLPzq51dF753M6JRXjBlfiz_WCi_8vy5JSUDPnrGOVomL40

As global warming accelerates, polar buttressing is collapsing. Over half of all ice sheets are now prone to sudden collapse, leading to rapid melting, threatening global sea levels.
More than half of the ice shelves holding Antarctic glaciers in place could crumble as the atmosphere warms. https://www.livescience.com/antarctic-ice-shelf-cracks-melting.html?fbclid=IwAR1qrl1vkJ4zRHqKRYISEgj_gwqzWFkObi7KfTjft-okY5iBx1_TsnvPadg
