NASA scientist says that error has long since been corrected and the increase in sea ice in Antarctica is real.
As readers know, we announced this paper (which was under embargo): Claim: Antartica record high sea ice partially an artifact of an algorithm
Cato’s Patrick Michaels and Chip Knappenberger said the whole thing was not an ice mountain, but a molehill: Of mountains, molehills, and noisy bumps in the sea-ice record writing:
“If the reason that the shift was undetected is because the data is so noisy, how important can it be?”
“The change since the turn of the century is about 1.3 million square kilometers, a mountain of ice,” “The step change is about 200,000, a molehill. That doesn’t sound like ‘much’ to us.”
“But, hey, if you don’t look too close — and we are sure our greener friends (or the reviewers) won’t (or didn’t) — you might believe that everything is OK with the reigning, model-based paradigm. In fact there’s’‘much’ that is wrong with it,”
The Daily Caller’s Michael Bastasch noted that other scientists agree.
Scientists with NASA, who developed the disputed algorithm to calculate sea ice extent, also challenged Eisenman’s view, including the scientist at NASA’s Goddard Space Flight Center in Greenbelt, Md., who developed the algorithm that is being criticized in the study.
“The apparent expansion is real and not due to an error in a previous data set uncovered by the Eisenman et al paper,” NASA’s Josefino Comiso told Live Science. “That error has already been corrected and the expansion being reported now has also been reported by other groups as well using different techniques.”
Antarctic sea ice continues to grow, well above that 200,000 sqkm value:

I hate it when that happens. On the plus side, once again, Joe Romm of ‘Climate progress’ looks like the chicken little for hire he truly is.
“The most important thing to know about Antarctica and ice is that a large part of the South Pole’s great sheet of land ice is close to or at a point of no return for irreversible collapse,” ThinkProgress’s Joe Romm wrote in his piece about the new study. “Only immediate action to sharply reverse CO2 emissions could stop or significantly slow that.”
Yep: sure looks near it is “at a point of no return for irreversible collapse” to me: /sarc
