Antarctica has confounded scientists, defying the dire predictions of scientists the South Pole would shrink and exacerbate sea level rise in the coming decades.
Climate models predicted Antarctic sea ice would shrink as the world warmed, and that warming would boost snowfall over the southern continent. Neither of those predictions have panned out, and now scientists say “natural variability” is overwhelming human-induced warming.
“Truth is, the science is complex, and that in most places and with most events, natural variability still plays a dominant role, and undoubtedly will continue to do so,” Chip Knappenberger, a climate scientist with the libertarian Cato Institute, told The Daily Caller News Foundation.
“This applies to goings-on in Antarctica as well as in Louisiana,” Knappenberger said, referring to the recent flooding in Louisiana activists have already blamed global warming for.
What recent studies have shown is that natural variability in the climate system plays a big role in the South Pole, and there are few signs of man-made global warming in Antarctica.
