ARCTIC CLIMATE EMERGENCY C
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

HOT-HOUSE EARTH ARCTIC RUNAWAY FEEDBACK CATASTROPHE UNDERWAY
The Arctic carbon sink has switched to source with "acclerating permafrost feedback under way"- thawing permafrost "could be releasing an estimated 300-600 million tons of net carbon per year"
July 2019 Arctic sea ice loss = 1 trillion tons CO2 emissions/ will speed up global warming by 25 years, with an enormous increase in Arctic amplified warming, permafrost thaw and feedback emissions- boosting global heating faster and faster
