Melting tundra releases methane, accelerating the increase in temperature. Rising temperature reduces polar ice, making oceans absorb more heat, accelerating heating. Climate pattern changes cause more frequent and larger wildfires, accelerating heating.
There are probably processes that work to reduce heating as it increases that I’m not aware of, but there are a lot of positive feedback processes which is concerning.
I believe the IPCC 1.5C was criticized because it included effects of a carbon sequestering process that hasn’t been invented yet. That’s pretty optimistic.
