Climate scientists, in an effort to avoid panic, are downplaying the calamity and timescale of this crisis. It's common knowledge in the climate science academic community that the 2018 IPCC report was overly conservative in its modelling of CC progression by lacking any mention of self reinforcing feedback loops.

The two most impactful of these loops are the Arctic sea ice reflectivity loss (less ice -> less incoming light reflected back into space -> more heat captured by earth -> less ice) and the Siberian arctic shelf methane loop, arguably the most devestating one because we already know it caused Earth's worst extinction[0], and it is beginning to happen again[1].

It will be refreshing to see if the scientific community's consensus on how silent to be about the severity of the climate crisis will change as the facts of how rapidly the feedback loops are progressing essentially implicate near-term (10-20 years) civilisational collapse.
