Remember that claim from NSIDC and Walt Meier that the Antarctic ice expansion was due to a ‘processing error’? …never mind

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 … Continue reading
