Global Science Report: Sea Ice Expansion in the Southern Hemisphere Is Real and Driven by Falling Temperatures

While there ’s been thousands of legacy media stories about the very real decline in summer sea-ice extent in the Arctic Ocean, we can’t findoneabout the statistically significantincrease in Antarctic sea ice that has been observed at the same time.Also, comparisons between forecast temperature trends down there and what ’s been observed are also very few and far between. Here’s one published in 2015:Observed (blue) and model-forecast (red) Antarctic sea-ice extent published by Shu et al. (2015) shows a large and growing discrepancy, but for unknown reasons, their illustration ends in 2005.For those who utilize and trust in the scientific method, forming policy (especiallymulti-trillion dollarpolicies!) on the basis of what could or might happen in the future seems imprudent. Sound policy, in contrast, is best formulated when it is based upon repeated and verifiable observations that are consistent with the projections of climate models. As shown above, this does not appear to be the case with the vast ice field that surrounds Antarctica.According to the most recent report by the Intergovernmental Panel on Climate Change (IPCC), CO2-induced global warming will result in a considerable reduction in sea ice extent in the Southern Hemisphere. Specifically, the report predicts a multi-model average decrease of between 16 and 67 percent in the summer and 8 to 30 percent in the winter by the end of the century (IPCC, 2013). Given the fact that atmospheric CO2 concentrations...
