>>8868802all of the feedbacks in the arctic are accelerating feedbacks.
they include wave ice, ice albedo (reflection), snow cover albedo, water vapor, ice-sheet melt, arctic river, black carbon, ocean acidification, and the ninth, the mother of all feedbacks, methaane.
the arctic has been warming 1 degree celcius per decade. the rest of the planet 0.15, a ratio of 7:1!
arctic anomolies at 20 celcius warmer equal 140% more arctic water vapor causing it to rain a lot more. ice has declined at 12% per deade and snow cover over 22% per decade, or even more because freight is faster.
fresh snow and ice albedo is about 90% reflective. with dark sea water, sunlight heats up the water bringing the albedo to 10%. if you compare the radiative forcing to the CO2 in combined ice and snow albedo, both are similar.
as the ice in the arctic centre shrinks, there is more water on the outside of this fetch. waves get higher, and winds get stronger with longer durations. waves pulverizing ice chunks is a huge feedback itself when they lift up and shatter it to pieces with a larger surface area.
methane from permafrost and seafloor algae causees jet stream waviness feedvvack, and the slowing of the ocean currents. warm salty heavier ocean water is sandwiched with colder water below, and 150 meters of colder fresher water overtop causes big waves to mix water, increasing the sea floor temperature, thawing out permafrost, essentially perforating the layer.
the eastern siberia arctic shelf of frozen permafrost is known to cover methane clathrate. now melting, the sediment is 7 degrees celcius warmer with areas of unfrozen ground acting as vents, or talax. for the clathrate there is no longer a layer, membrane, or plug to stop the methane from coming up.
vertical moulins are well-like shafts that melt and drill straight down into glaciers, bringing water underneath, turning the ice into swiss cheese. these moulins in the glaciers are analagous to the talax in permafrost.
