The Arctic and Antarctica are the air-conditioners for our planet. They take the hot air from the Tropics, cool it and send it back to the Tropics again. An increase of 0.5 degrees in average temperature at the Equator would mean an increase of as much as 4-6 degrees at the poles. This movement of heat from the equator to the poles has been following the same pattern for 10,000 years - since civilization began. Changing these patterns will affect our economy, people, crops, water supplies and pretty much everything we do.
