Why Other Continents are Much Warmer Than Antartica

 Why Other Continents are Much Warmer Than Antartica

The reasons behind why Antarctica is not much warming than other continents and southern Australia recording more droughts is now explained by researchers.

Researchers have found rising levels of carbon dioxide in the atmosphere are strengthening the stormy Southern Ocean winds which deliver rain to southern Australia, but pushing them further south towards Antarctica.

Lead researcher Nerilie Abram, from the ANU Research School of Earth Sciences, said with greenhouse warming, Antarctica is actually stealing more of Australia's rainfall. It's not good news - as greenhouse gases continue to rise we'll get fewer storms chased up into Australia.

She said as the westerly winds are getting tighter they're actually trapping more of the cold air over Antarctica.

Abram said that this is why Antarctica has bucked the trend. Every other continent is warming, and the Arctic is warming fastest of anywhere on earth.

While most of Antarctica is remaining cold, rapid increases in summer ice melt, glacier retreat and ice shelf collapses are being observed in Antarctic Peninsula, where the stronger winds passing through Drake Passage are making the climate warm exceptionally quickly.

By analysing ice cores from Antarctica, along with data from tree rings and lakes in South America, Dr Abram and her colleagues were able to extend the history of the westerly winds back over the last millennium.

"The Southern Ocean winds are now stronger than at any other time in the past 1,000 years," Abram said.

"The strengthening of these winds has been particularly prominent over the past 70 years, and by combining our observations with climate models we can clearly link this to rising greenhouse gas levels," she said.

The study has been published in the journal Nature Climate Change.
