Detailed explanation-1: -The Arctic is warming three times as fast and the global average. This is mainly because melting of snow and ice exposes a darker surface and increases the amount of solar energy absorbed in these areas (albedo effect).

Detailed explanation-2: -Where have some of the strongest and earliest impacts of global warming occurred? Some of the fastest-warming regions on the planet include Alaska, Greenland and Siberia.

Detailed explanation-3: -Polar regions and land areas are expected to see the largest temperature changes. Earth’s average global temperature is rising, but the amount of warming is not equal in all areas of the world.

Detailed explanation-4: -The Antarctic Ice Sheet is losing mass due to warmer air and water temperatures. In many areas where Antarctic land ice meets the ocean, large floating ice shelves form, areas particularly vulnerable to ocean melting. Warm ocean currents flowing under ice shelves are driving increasing melt.
