To us, a warmer ocean might feel pleasant. But the extra heat manifests underwater as an unprecedented series of major marine heatwaves, which can lead to mass death or mass migration for marine mammals, seabirds, fish and invertebrates and cause widespread coral bleaching.
Much of the abyssal ocean has warmed in recent decades, with the most rapid trends detected near Antarctica, in a pattern very similar to our model simulations.
Originally published by Scimex Media release From: Australian Science Media Centre BRIEFING ALERT: Is the Southern Ocean about to have its own ‘Day After Tomorrow’ moment? (Nature*) NEWS BRIEFING: Tuesday 28 March at 10:00 AEDT ONLINE The movie ‘The Day After Tomorrow’ tells the fictional story of catastrophic climatic effects following the collapse of the North Atlantic Ocean circulation, and now new Australian research suggests our own southern version of this deep ocean circulation may soon be about to collapse. The study, published in Nature,... View Article
"Now is the time to start cutting back the excess vegetation that grew over the last three years"
While the urgency for action has never been more pressing, we still hold the future in our hands - the choices we make today will decide our future for generations to come.
If the Southern Ocean continues to account for the vast majority of ocean heat uptake until 2100, we might see its heat content increase by as much as seven times more than what we have already seen up to today.
‘‘These triple events can be very impactful because you are not seeing the drying out of the soil and then more rain’’
At no time in Earth’s history, giant meteorites and super-volcanos aside, has our climate system been jolted by changes in atmospheric gas composition like what we are imposing today by our unabated burning of fossil fuels.
There are exciting opportunities for PhD projects in the Climate Change Research Centre and the School of Mathematics and Statistics at UNSW as part of the ARC Australian Centre for Excellence in Antarctic Science (ACEAS). What: The goal of ACEAS is to help the world community prepare for climate risks emerging from East Antarctica and the Southern Ocean by integrating knowledge of the ocean, atmosphere, cryosphere and ecosystems, and their interplay. ACEAS is a national-scale, University-led centre for excellence in Antarctic science... View Article
