Yet another amazing NSIDC fail. They posted bogus maps of multi-year sea ice this week, prompting Eric Holthaus to be shocked.
This is exactly the same claim David Barber made nine years ago.

NSIDC forgot to update the age of the ice, and have since corrected it. Multi-year ice actually covers about half of the Arctic.
Note: The ice age fields originally posted on Thursday, May 3, were incorrect. The ice age field has its “birthday” each September after the minimum, when all of the age values are incremented by one after the end of the summer melt season.

How did NSIDC manage to miss the birthday by eight months? Pretty spectacular incompetence.
Since 2009, there has been a large increase in multi-year ice. This is what multi-year ice extent looked like in 2009.

Two years ago I caught NSIDC making multi-year ice disappear.
Global warming is the biggest scam in science history. The Arctic isn’t cooperating, so scientists simply make stuff up.
