π Positive feedback loops where π temp -> π GHG emissions ->π temp are the scariest part of climate change.
AND YET in nature, positive feedback loops are WAY less common than negative feedback loops.
Where are all the negative feedback loops we can pin our hopes on?

A few examples of positive feedback loops:
Arctic methane bomb theory
Wildfires: heat->wildfires->released CO2
Silicate-carbonate cycle: heat->rising sea levels-> less surface area for siliate weathering (natural CO2 sequestration)->more CO2->heat

A few examples of negative feedback loops:
More CO2 -> faster biomass growth on land and ocean -> CO2 sequestered
(seems tenuous b/c that C will be respired back out)
Hotter water -> less shellfish -> less CO2 release in shell construction -> more C sequestered in ocean
(grim)

What are other examples of major negative feedback loops?
