Rising Ocean Temperatures

Greenhouse gas induced warming is increasing ocean temperatures causing loss of sea ice and a positive ice-albedo feedback. This occurs when more open water leads to more solar heat absorbed, which results in more open water.

Sea surface temperatures (SSTs) in the Chukchi and East Siberian seas have been rising since 2000. Increased SSTs are causing loss of sea ice, and the water that replaces the ice is absorbing more solar energy and thus inhibiting ice expansion in autumn. This also retards freezing and extends the impact of summer heat input into the fall and winter.
