1.5°C Tipping Points and Feedback Loops

Feedback loops
Personally, I don't believe stabilizing at 1.5°C is possible.

Climate is a sensitive mechanism. There are mathematical models and probabilities but... Just like Newton physics does not work with speeds of light, the existing models do not take into account all the potential feedback loops. Here I'm naming only a few most intuitive ones.

polar caps
White polar caps reflecting the sun rays are melting, dark ocean waters absorbing heat/

permanent frost
Permanent frost melting releasing natural gas.

ocean acidification
https://en.wikipedia.org/wiki/Ocean_acidification#Ecosystem_impacts_amplified_by_ocean_warming_and_deoxygenation

"ocean warming exacerbates ocean deoxygenation, which is an additional stressor on marine organisms"

forest fires
Less trees to capture CO2. More CO2 from fire itself.
