“Scientists have underrated the major role the Antarctic ice sheet plays in global climate variability, which helps explain why sea ice in the Southern Hemisphere has increased even while the Earth warms.
That’s the main finding of a study published Monday in the journal Nature, which examines global climate models of the past several thousand years that fail to account for climate variability in the paleoclimate record.
The researchers first analyzed the Scotia Sea, since most icebergs breaking off the Antarctica ice sheet pass through this region due to oceanic and atmospheric circulation, according to co-author Michael Weber.”
