While Arctic sea ice has declined remarkably since 1979, Antarctic ice has been unexpectedly stable. Experts acknowledge that existing climate models–which assume that CO2 emissions drive global sea ice loss–had predicted Antarctic sea ice would have declined over the last several decades–and would decline even more in the future. They’ve finally admitted they were wrong.
John Turner (British Antarctic Survey) and Josifino Comiso (NASA) in a NATURE paper in 2017:
“Current climate models struggle to simulate the seasonal and regional variability seen in Antarctic sea ice.“
