But there are so many feedbacks that have not yet been discovered and that have not been included in the models, that all these projections are subject to enormous uncertainties. And then there are uncertainties about the reverse process which is that of the fixation of organic matter, of carbon, by vegetation. if it's warmer, vegetation grows. The herbaceous tundra is replaced by shrub tundra. There is more biomass in shrubs than in grasses. So Arctic soils will serve as carbon sinks when permafrost will serve as a source of carbon. In short, there are still too many uncertainties.
Forcely bad, also because of the methane that is 25 times (some sources say 30 times) more greenhouse gas generator than the Co2.
