The Impact Of Climate Change To Polar Regions[[image:Polarsm.jpg align="right"]]
Polar Regions include the Arctic in the Northern Hemisphere and Antarctic in the Southern. Compared to other places in the world, the polar regions are expected to experience the greatest rates of warming. Over the past ten years the Arctic's average temperature has risen almost twice as fast as the rest of the world, and with one problem there's another. The warmer weather is melting ice causing the sea levels to rise. However, it's not the actual ice that's melting playing the biggest part in the rising sea levels, but the displacement of water. It's quite simple, the ice only has to melt just enough to brake away from the grounded areas and float free. Once detached, it's the same as say, adding an ice block to a glass of coke, causing it to rise. The average global sea level has risen 0.25 - 0.5cm in recent years. If the problem gets worse, cities will flood and islands will disappear! However some scientist's are questioning whether the rising in temperatures are due to a certain natural process, as Antarctica has melted once before, 3 million years ago. Then again other scientist's believe that the warming to polar regions could lead to reduced sea levels, because the warmer weather could mean more evaporation, meaning more snowfall. Then if more snow started to fall than ice started to melt, the levels would lower and the polar regions would expand. But for now it seems the concern is set on the opposite.

The Impact Of Climate Change To Animals In Polar Regions
I would be pretty sure that the animals living in those polar regions are feeling the heat if not on land, in the water. The Arctic and Antarctic are home to many species of wildlife, polar bears, seals, walruses, penguins,caribou and many more, plus a wide range of sea life.
