It is quite possible that we are well past half - way — maybe at 75 % in terms of loss of
arctic sea ice mass.
Not exact matches
Lower Atmosphere is warming, oceans upper layers are warming,
arctic summer
sea ice is disappearing, WAIS and Greenland are both losing
mass annually and the majority of the earths glaciers are losing
mass too.
The models are certainly wrong when it comes to simulating the rate of
arctic sea ice loss, or the full dynamics of
ice sheet
mass balance changes.
And, once the summer season is passed, the ever - colder
Arctic air
masses remove even more heat from the under -
ice water up through the
sea ice by conduction into the -25 deg
arctic air.
The most recent calculations of
ice mass balance in the antarctic also do indicate loss of
ice, though nothing close to the changes seen in the
arctic sea ice and Greenland
ice sheet.
