Investigating physical and chemical changes in atmospheric circulation, ozone depletion, temperatures and sea-ice extent in both Polar Regions can help determine how much of the observed change is due to human activity and how much is a result of natural factors. Unique chemical processes occur in the atmosphere above Antarctica and the Arctic reveal much about our changing world.
