Arctic sea ice extent is the highest in the past thirteen years and sixth highest this century.
NSIDC reports this as “sixteenth lowest in the satellite record”
“January 2022 finished as the sixteenth lowest extent in the satellite record”
In other words, they had no idea what they were talking about fifteen years ago.
Using their cherry-picked start point of 1979, they say January Arctic sea ice extent is declining at 42,800 sq. km./year.
This is down from four years ago when they reported 47,700 sq. km./year.
NSIDC also hid all the inconvenient satellite data prior to 1979.
“The American Navy Joint Ice Center has produced weekly charts which have been digitised by NOAA ….. Since about 1976 the areal extent of sea-ice in the Northern Hemisphere has varied about a constant climatological level but in 1972-1975 sea-ice extent was significantly less.
They hid the low ice extent and volume from the 1950s.
Although the idea that a solid ice sheet covers the central Arctic has lingered stubbornly in the popular fancy, the northern cap of ice worn by our planet is actually a thin crust—on the whole, only about seven feet thick—over an ocean two miles deep in places.
And no mention of the fact the Arctic was ice-free 6,000 years ago.
Eight years ago NSIDC said surface melting of Greenland’s ice sheet is one sign of climate change.
Greenland’s surface mass balance has been well above the 1981-2010 average over the past six years, with inly one year significantly below the mean.
