Sea ice levels in the Arctic and Antarctic are growing at a record-slow pace this season, according to multiple sources. While this year’s summer low for the northern hemisphere wasn’t as bad as the current record, set in 2012, the autumn rebound is falling well short of both the fall of 2012’s growth rate and the 37-year average. The Antarctic is following suit, with the summer melt shrinking the ice there at a record speeds.

Global sea level rise has been assumed to have been rising at an average rate of 1.5 centimeters (0.6 inches) per decade since 1900, as measured by NOAA. However, a new study has cast that figure into doubt: after having taken regional sea level increases into account, the previously accepted rate may be off by a great deal — from 5 to 28 percent in some regions.

The problem comes from the fact that sea level measurements have been historically taken from coastal tide gauges, from roughly a dozen select sites around the northern hemisphere. It was assumed in the past that ocean levels were rising relatively evenly across the globe, however:

Framework Convention on Climate Change, and reverse various environmental initiatives put in place by the previous administration. Needless to say, these plans do not bode well for the environment.
