Recently the IPCC AR6 highlighted trend of Arctic Amplification, where Arctic Region is warming 2.5 times faster then rest of Earth.
Body · points
Role of Polar cryosphere
(1) Wind system → eg polar vortex creation and polar wind cell.
(2) Temperature Regulation → eg cooling due to albedo of cryosphere.
(3) Fresh water → eg - Polar ice caps sources
(4) Pressure condition Regulation → By high pressure in polar region
(5) Sea water regulation → By trapping water in form of ice → no rise in sea temperature.
(6) Role in Monsoon system → Recent study of IMD highlights key role.
factors Responsible for rapid warming
(1) Climate change and rise in green house gas emission
(2) Black carbon → melts the ice
(3) Arctic amplification → due to reduction of albedo of ice
(4) Human intervention in the region Eg Arctic Mission of USA.
(5) Compounding of the effect Eg Tripple planetary crisis
(6) Emissions of per fluoro acids → loss of polar stratospheric clouds
(7) Natural process Role → volcano in greenland
Way forward
→ Reduction in emission of green house gases → R&D for adaptation → Mitigation of effect → Reversing of trend eg Technology like artificial glacier.

Thus, global collaboration and a dedicated Arctic Treaty is need of the hour to save our planet from this ticking bomb.
