- Scientists use climate models to determine the causes of climate change in the two polar regions, finding that only when they included human influences could they explain the rise in temperatures in both areas. However, other scientists show climate models are extremely limited tools in trying to mimic what happens in nature. Also, the report looks largely at the Antarctic peninsula - which makes up only TWO per cent of the continent - and the eastern and western coastal regions, where they have found warming. The Antarctica continent itself is cooling. The report focuses on temperature changes going back to 1900 and up to the present, but doesn’t include earlier periods when areas in the Arctic were actually warmer than they are today and were not affected by man-made greenhouse gases.
