Four years ago, climate scientists explained how global warming causes above normal Antarctic sea ice.
Two years ago, climates scientists blamed low Antarctic sea ice extent on global warming.
And now, Antarctic sea ice extent is very close to the 1979-1990 mean. This is also no doubt due to global warming and record hot temperatures.
Global warming is like Goldilocks. Too hot, too cold, or just right – all caused by a 0.0001 mole fraction increase in a harmless, essential trace gas over the past century.
