The Arctic shifts to a new normal

On 5 September 1980, when the Arctic sea-ice cover reached its minimum extent for the year, it blanketed much of the Arctic Ocean and choked the inter-island channels of Canada’s Arctic Archipelago. Not only did ice extend over 7.5 million square kilometers, almost equal in area to the contiguous 48 US states, but it was an old, and thus thick, ice cover: 62% was multiyear sea ice—that which survives one or more summer melt seasons—and 38% was first-year sea ice. The age and thickness of the ice made it resilient to atmospheric and oceanic forcing, such as solar radiation, storms, and air and water temperatures. Consequently, the seasonal cycle of winter advance and summer retreat was thought to be in a near steady state.

The extensive, thick ice cover that persisted through the end of the summer was considered normal at the time and for many years afterwards. It was expected of a region generally perceived to be cold, hostile, and isolated from the rest of the world, a zone of Cold War confrontation yet of little immediate consequence to most people. Northern residents would rightly have disagreed with that characterization, and multinational corporations were finding and profitably exploiting large energy and mineral reserves. The Prudhoe Bay oil field in northernmost Alaska had been producing for three years—and continues to do so—and the Polaris mine on Little Cornwallis Island in the Canadian Arctic Archipelago was to begin 22 years of lead and zinc production in 1981. And scientists continued to visit, almost exclusively in the summer—rather like migratory birds—to conduct fieldwork.

In October 1980 Syukuro Manabe and Ronald Stouffer (both then working at the National Oceanic and Atmospheric Administration’s Geophysical Fluid Dynamics Laboratory) reported the results of a numerical experiment on the sensitivity of global climate to a quadrupling of atmospheric carbon dioxide concentration.1 The consequences for the Arctic were profound. Their model projected an asymmetric seasonal surface air-temperature response—greater winter warming than summer warming in the Arctic itself, and greater winter and annual warming in the Arctic than at lower latitudes. It also projected a large decline in sea-ice extent and thickness.

Whereas Manabe and Stouffer’s simulation quadrupled the atmospheric CO2 concentrations in its artificial world, the actual increase to date has been much lower. At Barrow in northernmost Alaska, for example, the mean CO2 concentration of 385 ppm in September 2012 was only 15% higher than the 331 ppm of September 1980. And yet profound changes in surface air temperature, sea ice, and numerous other environmental conditions have occurred in the Arctic....

Where did it go the hundreds of other times this situ has occurred here on planet earth the past, oh 750 million years?

Many if not most of those occurrences were tenfold worse than anything we are or will experience in the next 2-5 hundred years.

Stop acting like this is the FIRST time this has EVER happened. Cus that aint science.

he effects of Global Warming down on the ICE (WILLY FIELD, ROSS ISLAND) this past March. Record sea ice thickness in the ROSS SEA extended the season for flight ops into the entire month of March. First time "EVER".

BTW, Willy Field is not "THE ONLY OPEN AIRFIELD IN ANTARCTICA".
