The latest recycled argument from WUWT (and echoed by others) is the oft-repeated fallacy that, "since Antarctica's sea ice is growing, scientists are all wrong about climate change."
Early in June, Antarctic Climate expert, Guy Williams, providers a prescient rebuttal to this argument, writing in The Conversation about "the paradox of increasing Antarctic sea ice." Williams explained that, for one thing, the continent is experiencing both sea ice growth and loss, depending on the region. While overall sea ice extent has grown, there have been significant losses in some areas.
Further, there is "a pattern of low atmospheric pressure" in the Pacific Ocean called the Amundsen Sea Low that pushes warm air south and cold air north. At the Bellingshausen Sea, where the warm air meets the continent, sea ice is melting. Meanwhile, the displaced cold air combined with the winds circling the continent (known as the Southern Annular Mode or SAM for short) are driving sea ice growth in the Ross sea.
And it turns out, SAM is being strengthened by ozone depletion and greenhouse gas emissions. So yes, the expansion of Antarctic sea ice is actually a symptom of human emissions!
