Arctic sea ice is melting at a record pace – and every summer looks grimmer. This past summer saw the ice pack at its fourth-lowest level on record, and the overall trend in recent decades suggests this will only continue.
“Using satellites, scientists have found that the area of sea ice coverage each September has declined by more than 40 percent since the late 1970s, a trend that has accelerated since 2007,” according to the recent report “Arctic Matters: The Global Connection to Changes in the Arctic” by the National Research Council of the National Academies.
The report added that by the end of each of the eight summers from 2007 to 2014, Arctic sea ice extent was over less area than at any time in the preceding three decades.
In addition to rapid melting of the sea and land ice in the Arctic, temperatures there are warming at least twice as fast as those of the rest of the planet – provoking other dramatic changes.
Massive wildfires on frozen ground, resulting from increasingly dry conditions caused by anthropogenic climate disruption (ACD), are becoming common; this phenomenon is unprecedented over at least the last 10,000 years.
