ice extent stays on the long-term downward trajectory that will eventually lead to seasonally ice free conditions as the Arctic continues to warm in response to rising atmospheric concentrations of Greenhouse gases.
Besides the fact that they don’t present any evidence tying greenhouse gases to Arctic ice extent, their graph of historical data doesn’t match the historical record. NSIDC shows very little ice loss prior to 1940, but scientists at the time reported that the ice had lost one third of its area and half its thickness. Obviously this loss was not due to rising greenhouse gases, making NSIDC’s bogus graph even more misleading.
They can’t explain the pre-1940 warming and ice loss, and don’t even acknowledge that it happened. Junk science at its worst. NASA gave them a boost in this propaganda effort by making the 1940 Arctic warmth disappear.
