Arctic Amplification

In the context of changes brought about by global warming, any change in the surface air temperature and the net radiation balance tend to produce larger changes at the north and south poles. This phenomenon is known as polar amplification; these changes are more pronounced at the northern latitudes and are known as the Arctic amplification.

• The ice-albedo feedback, lapse rate feedback, water vapour feedback and ocean heat transport are the primary causes of this amplification.
• According to a recent study, the Arctic is heating four times faster than the rest of the planet. The warming is more concentrated in the Eurasian part of the Arctic.
