Global warming • Temperatures on the Antarctic coast are warmer than temperatures further inland • Temperatures on the Antarctic Peninsula are rising • Melting ice is natural, but problems are caused when there is too much melting ice • Humans have increased the amount of greenhouse gases in the atmosphere • There is a hole in the ozone layer above Antarctica Introduction Scientists believe that the Earth's climate is being altered due to changes in the atmosphere known as the greenhouse effect . The greenhouse effect is particularly significant in the polar regions of the Arctic and Antarctic, where much of the world's fresh water is frozen in huge quantities of ice. On the Antarctic Peninsula, temperatures have been recorded as increasing two to three times more quickly than the rest of the Earth. How ice melts in Antarctica Hardly any ice melts in the centre of Antarctica because it is too cold. Ice travels from inland Antarctica to the coast via glaciers. This continual process transfers ice along the glacial rivers, eventually reaching the ocean. When icebergs break away from glaciers and float into the ocean, most of the melting ice is taken from underneath the iceberg. It is difficult to tell how much ice melts from icebergs because we cannot see it.
