Antarctic winter ice gets bigger; Arctic shrinks

OSLO (Reuters) – The amount of sea ice around Antarctica has grown in recent Septembers in what could be an unusual side-effect of global warming, experts said on Friday.

In the southern hemisphere winter, when emperor penguins huddle together against the biting cold, ice on the sea around Antarctica has been increasing since the late 1970s, perhaps because climate change means shifts in winds, sea currents or snowfall.

At the other end of the planet, Arctic sea ice is now close to matching a September 2007 record low at the tail end of the northern summer in a threat to the hunting lifestyles of indigenous peoples and creatures such as polar bears.
