Which of the following statements is/are correct with reference to the Arctic warming?

A. Arctic has warmed three times more quickly than the planet as a whole, and faster than previously thought.

B. Climate scientists have known for decades that the Northern Hemisphere was warming faster than the warmer Southern Hemisphere.

C. Both A & B

D. None of these

Explanation:

The Arctic has warmed three times more quickly than the planet as a whole, and faster than previously thought. Climate scientists have known for decades that the Northern Hemisphere was warming faster than the warmer Southern Hemisphere. Arctic sea ice looks set to be an early victim of rising temperatures, with each fraction of a degree making a big difference, the chance of it disappearing entirely in summer is 10 times greater if Earth warms by 2 degree Celsius above pre-industrial levels compared to 1.5 C, the goal set by the 2015 Paris Accord.
