The effective pressure under the Antarctic ice sheet describes how easily the ice flows atop the layer of water separating the ice from the bedrock. The new maps combine the bed topography, ice thickness, subglacial hydrology and base melt. (Image credit: Shivani Ehrenfeucht et al., 2024; CC-BY-NC-ND) An extensive model…

If you’ve been around the world a couple of times or maybe more, you’ll have seen the sights of gum trees on almost every foreign shore. But climate change bringing hotter, drier conditions means the trees – especially plantations of Eucalyptus globulus or Tasmanian blue gum grown for paper –…

Antarctic ice shelves are shrinking mainly due to frequent small calving events, while major iceberg break-offs remain rare and unchanged in frequency. A recent study by geologists and geographers at the University of Florida provides new insights into the impact of climate change on Antarctic ice shelves...Read More

University of Otago -- Ōtākou Whakaihu Waka scientists have successfully analysed more than 30 years of vital data on the thickness of landfast sea ice in Antarctica's McMurdo Sound, which will prove useful to measure future impacts of climate change. The study, published in the Journal of Geophysical Research: Oceans,…

The size of the Antarctic ice sheet can be hard to comprehend. Two kilometres thick on average and covering nearly twice the area of Australia, the ice sheet holds enough freshwater to raise global sea levels by 58 metres. Ice loss from this sheet is projected to be the leading…
