The Godfather of Global Warming can’t pay his gambling debt (dire predictions). He’s asking for more time for his horse to win.
Hansen claims that his models predicted Antarctic sea ice expansion
In this sense, expanding Antarctic sea ice might be anything but good news.
Indeed, in the troubling scenario outlined by Hansen and his colleagues, it’s part of a series of feedbacks that lead to rapid sea level rise. “Amplifying feedbacks, including slowdown of [the Southern ocean’s overturning circulation] and cooling of the near-Antarctic ocean surface with increasing sea ice, may spur nonlinear growth of Antarctic ice sheet mass loss,” write Hansen and his colleagues.
“Effects of freshwater injection and resulting ocean stratification are occurring sooner in the real world than in our model,” they add.
Reached by phone, Hansen added that one reason he thinks the model he is using is is right — and other models are not — is that it captures Antarctic sea ice expansion. “All the other models have sea ice disappearing as the planet get warmer,”…
