“Sudden Reversal in Antarctic Sea Ice Complicates Argument by Climate-Change Doubters” Chris Mooney, Chicago Tribune, 16 February 2017

“Record low sea ice extent in the Arctic has, in a sense, become old news. But now the Antarctic is getting into the act. There are certainly many questions out there as to why Antarctic sea ice is also at a record low, but we can't deny the reality that things are changing and they are changing fast

Climate change doubters' favorite argument has lately been that floating sea ice around Antarctica has been growing. That raises doubts --they claim-- about human-induced climate change--. Climate scientists, however, retorted: “Floating sea ice in the Arctic is  actually  shrinking, as are Arctic and Antarctic glaciers. We don't completely understand all the factors behind the huge and complex Antarctic sea ice system. Don't leap to the conclusion that this strange behavior in floating Antarctic ice, which --it is true-- has been growing slightly recently, puts into question climate science”. Now, however, the doubters’ argument just got even more difficult. After seeing a record high for total extent in the year 2014, Antarctic sea ice had been running very low in late 2016 and early 2017. And now, as of data recorded by the National Snow and Ice Data Center, the extent of Antarctic sea ice now appears to have hit a record low (although scientists still have to confirm this and have not made an official announcement yet). It's summer in Antarctica right now, and floating sea ice on Monday only covered 2.287 million square kilometers, according to "near-real-time data" from the National Snow and Ice Data Center. "Record low sea ice extent in the Arctic has, in a sense, become old news," said Mark Serreze, Director of the National Snow and Ice Data Center. "But now the Antarctic is getting into the act. There are certainly many questions out there as to why Antarctic sea ice is also at a record low, but we can't deny the reality that things are changing and they are changing fast”. We don't fully understand what's going on with this system. Which is precisely why it's so dangerous to cite Antarctic ice to undermine the overwhelming evidence of climate change elsewhere.
