As it decreases, the lack of Arctic sea ice could reshape the economy of the region, opening previously inaccessible areas for oil and gas extraction and shipping.

We call this the Charney climate sensitivity, because it is essentially the case considered by Charney (1979), in which water vapor, clouds and sea ice were allowed to change in response to climate change, but GHG (greenhouse gas) amounts, ice sheet area, sea level and vegetation distributions were taken as specified boundary conditions.

Earlier this week, scientists confirmed the area of Arctic Ocean covered by sea ice — known as sea ice extent — reached a record low in November.

Paul D... As a part - time alarmist I would answer that with a little bit of extrapolation added to some warnings of climate scientists I guess the worst case scenario at least includes the total collapse of the WAIS, creating tsunamis at least all over the Pacific rim, the subsequent sea level rise of c. 7m will destroy most of the remaining harbours, communication centers near coasts, next up would be the melting of the collapsed ice in the southern ocean altering the climate of the entire southern hemisphere, making it near - impossible to guess what areas are good for similar agriculture as before, leading to massive movements of peoplAs a part - time alarmist I would answer that with a little bit of extrapolation added to some warnings of climate scientists I guess the worst case scenario at least includes the total collapse of the WAIS, creating tsunamis at least all over the Pacific rim, the subsequent sea level rise of c. 7m will destroy most of the remaining harbours, communication centers near coasts, next up would be the melting of the collapsed ice in the southern ocean altering the climate of the entire southern hemisphere, making it near - impossible to guess what areas are good for similar agriculture as before, leading to massive movements of peoplas before, leading to massive movements of people.
