Key Facts:<\/p>\n

A team of experts say the rapid and potentially irreversible changes happening across Antarctica\u2019s ice, ocean and ecosystems will accelerate climate impacts worldwide.<\/p>\n

The changes happening now in Antarctica will have serious consequences for Australia and beyond unless urgent action is taken to cut global carbon emissions, according to new research\u00a0published today<\/a>\u00a0in\u00a0Nature.<\/p>\n

Researchers from UNSW Sydney and The Australian National University (ANU) are part of an international team who say the large and sudden changes happening in Antarctica are not only connected but accelerating.<\/p>\n

Lead author Dr Nerilie Abram, Chief Scientist at the Australian Antarctic Division (AAD), says there is an urgent need to stabilise Earth\u2019s climate and prepare for widespread impacts.<\/p>\n

\u201cRapid change has already been detected across Antarctica\u2019s ice, oceans and ecosystems \u2013 and this is set to worsen with every fraction of a degree of global warming,\u201d says Dr Abram, who carried out this study during her time as Professor of Climate Science at ANU.<\/p>\n

Co-author Professor Matthew England from UNSW says there are consequences for Australia.<\/p>\n

\u201cThese include rising sea levels that will impact our coastal communities, a warmer and deoxygenated Southern Ocean that\u2019s less able to remove carbon dioxide from the atmosphere \u2013 leading to more intense warming in Australia and beyond \u2013 and increased regional warming from Antarctic sea ice loss.\u201d<\/p>\n

Melting land and sea<\/p>\n

Sea ice is the frozen seawater that surrounds Antarctica.<\/p>\n

Dr Abram says the sudden loss of sea ice in the region has a range of knock-on effects.<\/p>\n

\u201cThis includes making the floating ice shelves around Antarctica more susceptible to wave-driven collapse.\u201d<\/p>\n

She warns the West Antarctic Ice Sheet (WAIS) is at severe risk of collapse as global carbon dioxide levels continue to rise. This loss would raise sea levels by more than three metres, threatening coastal cities and communities worldwide.<\/p>\n

\u201cSuch a collapse would result in catastrophic consequences for generations to come,\u201d Dr Abram says.<\/p>\n

Wildlife under threat<\/p>\n

Much of Antarctica\u2019s wildlife depends on sea ice to breed.<\/p>\n

\u201cThe loss of sea ice brings a heightened extinction risk for emperor penguins, whose chicks depend on a stable sea ice habitat prior to growing their waterproof feathers,\u201d Prof. England says.<\/p>\n

\u201cThe loss of entire colonies of chicks has been seen right around the Antarctic coast because of early sea ice breakout events.<\/p>\n

\u201cSome colonies have experienced multiple breeding failure events over the last decade.\u201d<\/p>\n

The researchers warn other species are also under threat, including krill, seals and several other penguin species. Tiny ocean plants that many animals depend on for food \u2013 phytoplankton \u2013 are also affected by warming and acidification.<\/p>\n

\u201cAnother potential risk is a collapse in the Antarctic overturning circulation, which would mean vital nutrients remain at the seafloor instead of being recirculated back to the surface where biological systems \u2013 including marine animals \u2013 depend on them,\u201d Prof. England says.<\/p>\n

Already fragile<\/p>\n

Dr Abram says both sea ice loss and a slowdown in deep ocean circulation are already showing signs of being more sensitive to warming than previously thought.<\/p>\n

\u201cAs sea ice is lost from the ocean surface, it is also changing the amount of solar heat being retained in the climate system. That is expected to worsen warming in the Antarctic region,\u201d Dr Abram says.<\/p>\n

\u201cOther changes to the continent could soon become unstoppable, including the loss of Antarctic ice shelves and vulnerable parts of the Antarctic ice sheet that they hold behind them.\u201d<\/p>\n

Future planning needed now<\/p>\n

Dr Abram says efforts through the Antarctic Treaty System to reduce pressure on ecosystems are important \u2013 but won\u2019t be enough on their own.<\/p>\n

\u201cWhile critically important, these measures will not help to avoid climate-related impacts that are already beginning to unfold,\u201d she says.<\/p>\n

\u201cThe only way to avoid further abrupt changes and their far-reaching impacts is to reduce greenhouse gas emissions fast enough to limit global warming to as close to 1.5 degrees Celsius as possible.<\/p>\n

\u201cGovernments, businesses and communities will need to factor in these abrupt Antarctic changes that are being observed now into future planning for climate change impacts, including in Australia.\u201d<\/p>\n
