> “The planet as a whole is doing what was expected in terms of warming. Sea ice as a whole is decreasing as expected, but just like with global warming, not every location with sea ice will have a downward trend in ice extent,” Parkinson said.
> Since the late 1970s, the Arctic has lost an average of 20,800 square miles (53,900 square kilometers) of ice a year; the Antarctic has gained an average of 7,300 square miles (18,900 sq km).

The sea level is currently rising at about 3mm/yr (~1.2in/decade). The sea level is about 8 inches higher now than in 1870, and the rate of rising is increasing (+0.016mm/yr^2).
