Opposite sea ice trends? [Credits: NASA Goddard Space Flight Center/Joy Ng]
Climate modellers need yet more and bigger computers to stand a chance of eradicating faulty sea ice projections in the polar regions, apparently. Meanwhile, they believe there must be some ‘delay’ in their long-predicted but not (yet?) happening Antarctic sea ice decline. Quote: “Our study supports the hypothesis that climate models and projections of the Antarctic sea ice will be far more reliable as soon as they are capable of realistically simulating a high-resolution ocean, complete with eddies”.

Despite global warming and the sea-ice loss in the Arctic, the Antarctic sea-ice extent has remained largely unchanged since 1979, says Eurekalert.
However, existing climate model-based simulations indicate significant sea-ice loss, contrary to actual observations.
As experts from the Alfred Wegener Institute have now shown, the ocean may weaken warming around Antarctica and delay sea-ice retreat.
