Arctic sea ice decline

The Arctic sea ice decline has occurred in recent decades by sea ice in the Arctic Ocean melting faster than it refreezes in the winter. The IPCC's Fourth Assessment Report (2007) stated that greenhouse gas forcing is predominantly responsible for the decline in Arctic sea ice extent. Implications of arctic sea ice decline may include: Ice-free summer, tipping point, amplified arctic warming, polar vortex disruption, atmospheric chemistry changes, atmospheric regime changes, changes to plant, animal, and microbial life; changed shipping options and other impacts on humans.
