The most obvious ramification of this has taken the form of dramatically milder winters in the far north, coupled with temperature increases in the waters of the Arctic Ocean - both of which are dramatically increasing the melting of the sea ice, which is leaving more of the water's surface exposed, thus allowing more heat to reach the ocean during the summer. This process is likely the most well-known and most important feedback loop in ACD today - and because of it, land ice and permafrost in the Arctic are melting at a record pace.
Despite the remoteness of the Arctic, the region is deeply linked to the rest of the planet: Everything from our weather, to coastal flooding, to what we eat is tied to the Arctic and the events that are rapidly changing it.
Since the cold waters of the Arctic absorb more carbon dioxide than the more temperate waters that fill most of the rest of the globe, the Arctic Ocean is far more sensitive to ocean acidification. Add to that the fact that declining summer sea ice is exposing even more of that ocean, which is allowing even more carbon dioxide from the air into the waters.
The Arctic Circle contains an area that is roughly 6 percent of the Earth's surface, yet the dramatic evidence of its impact on the rest of the planet is mounting. Some of that evidence is now taking the form of melting land ice that is generating sea level rise.
