ï»¿ï»¿What is Polar Amplification?
Land masses heat up and cool down faster than water. Ice and snow in the Northern Hemisphere reflect back sunlight to outer space, and the rate of reflected light is called albedo (meaning ‘white’ in Latin). When the albedo is lowered, the more solar energy is retained, thus increasing the temperature. When temperature is increased, more ice is melted, and thus slowly lowering the albedo further. This cycle feeds arctic amplification. This also means that the Arctic is shrinking, and sea levels are rising.
Global warming is not uniformly evident in all parts of the world, as evident with polar amplification. But polar amplification has global repercussions, setting off chain reactions such as climate change, longer typhoon seasons, flooding, droughts etc.
