The world’s leading global warming expert/prophet, James Hansen of Columbia University and NASA, says the Arctic will be ice-free no later than this year. His work is based on settled science which 97% of the world scientists agree on.
The basic physics behind this is that ice doesn’t melt at -30C.
Arctic sea ice extent is near the 1981-2010 median everywhere except for the Bering Sea.
Arctic sea ice is very thick, and volume continues to increase.
The melt season near the North Pole is only 70 days long, and in recent years has been colder than normal.
It is difficult to melt fifteen feet of ice when the melt season is very short and temperatures rarely get above 1C. Nevertheless, NASA leading expert says the Arctic will be ice-free this summer. NASA also says we will have a new ice age by the year 2021.
It is basic physics that ice doesn’t melt below the freezing point, and basic economics that many scientists will say whatever is necessary to keep funding coming in.
