Arctic Climate Emergency

cn2

IPCC AR5 2014 WG2 SPM p. 15. ‘Examples that could lead to substantial impact on climate [i.e., amplifying carbon feedback] are the boreal-tundra Arctic system... carbon stored in the terrestrial biosphere (e.g., in peatlands, permafrost, and forests)'

 

IPCC  AR4  2007 These [Arctic] changes will have cascading effects on key regional bio-physical systems and cause global climatic feedbacks

The Arctic snow and summer sea ice cooling albedo is the 'air conditioner' of the entire Northern Hemisphere.

 

Its loss will affect the world's best northern hemsiphere food producing regions due to increased climate variability, extreme heat and drought, and damaging floods
