Government ice measurement agency caught altering measurements to make 5-year-old ice appear to be at “its smallest level” ever recorded

Tony Heller, the dogged data analyst who blogs as Steven Goddard, has previously caught the NSIDC (National Snow and Ice Data Center) cheating, just as Arctic sea ice extent was about to cross above the 1979-2000 average.

The NSIDC changed their measurement system to hide the fact that Arctic ice was growing to above-average levels.

Now Heller has caught the NSIDC cheating again. The agency has been promoting a claim that 5-year-old-plus ice is disappearing in the Arctic.

Heller had been carefully monitoring the agency’s weekly data reports, and noticed that just before the agency’s charts for ‘4-year-old’ ice was about to turn 5 years old (and show that 5-year-old ice is growing, not declining), the agency altered their measurement system! See here.
