Arctic warming

Context

According to the recent study concluding that the Arctic is heating four times faster than the rest of the planet. 

?What is Arctic amplification? 

• Global warming, the long-term heating of the earth’s surface, expedited due to anthropogenic forces or human activities since pre-industrial times and has increased the planet’s average temperature by 1.1 degrees Celsius. 
• While changes are witnessed across the planet, 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. 

Causes

• Among the many global warming-driven causes for this amplification, the ice-albedo feedback, lapse rate feedback, water vapour feedback and ocean heat transport are the primary causes.
