Today’s junk science comes from NASA:
New NASA research has found that increases in the rate at which Arctic sea ice grows in the winter may have partially slowed down the decline of the Arctic sea ice cover.
As temperatures in the Arctic have warmed at double the pace of the rest of the planet, the expanse of frozen seawater that blankets the Arctic Ocean and neighboring seas has shrunk and thinned over the past three decades. The end-of-summer Arctic sea ice extent has almost halved since the early 1980s. A recent NASA study found that since 1958, the Arctic sea ice cover has lost on average around two-thirds of its thickness and now 70 percent of the sea ice cap is made of seasonal ice, or ice that forms and melts within a single year.
But at the same time that sea ice is vanishing quicker than it has ever been observed in the satellite record, it is also thickening at a faster rate during winter. This increase in growth rate might last for decades, a new study accepted for publication in Geophysical Research Letters found.

The paper goes on to look at why the Arctic freezes during winter. But here’s a clue I offer free of charge to the experts at NASA:
THE POLAR NIGHT
As most schoolkids probably know, the Arctic never sees the sun during winter. Unsurprisingly, it gets very cold, with temperatures 30C below freezing.
Never mind the Arctic Ocean, I suspect even hell would freeze over!

As sensible minded sceptics have been pointing out for years, summer Arctic sea ice will never disappear whilst so much new ice grows every winter.
There are also two very misleading statements in that section I have quoted:
1) As temperatures in the Arctic have warmed at double the pace of the rest of the planet, the expanse of frozen seawater that blankets the Arctic Ocean and neighboring seas has shrunk and thinned over the past three decades.
While technically true, it omits the highly relevant fact that temperatures around the Arctic plunged sharply between the 1940s and 1980s, conveniently just before NASA’s “past three decades”:

2) But at the same time that sea ice is vanishing quicker than it has ever been observed in the satellite record
This is an outright lie.
Summer sea ice extent, which is being referred to, fell between 1980 and 2007, but since then has remained pretty stable.

It is sad that NASA’s reputation, hard earned over the years, is being trashed by a small minority who are more interested in propaganda.
