Dear MEL Topic Readers,
World's sea-ice falls to record low
Ice does cool the water around it when it melts. But sea ice around the north and south poles does more to the planet. It reflects substantial Sun’s energy back into space and keeps the planet cooler. When the ice layer shrinks, the ocean below the ice absorbs more heat and warms the planet further. Unfortunately, as polar regions are warming faster than the global average, the amount of polar sea ice is declining steadily. In fact, it is found that the natural cooling effect of polar sea ice has declined by about 14% since the 1980s. The thinner the ice cover is, the stronger the impact weather events could cause, resulting in more sea ice melting. Then sea levels rise further and extreme weather events occur more frequently. And of course, the lives of polar bears and penguins are threatened. It seems like the door of the freezer has opened and the ice inside has started melting.
