Since 1958, the US has led on Antarctic diplomacy and science. Trump’s funding cuts will diminish US capacity in Antarctica as China expands its presence.
A parliamentary report has called on for a second icebreaking vessel and more reliable funding for Antarctic research.
The scientific and broader community must join together to advance Southern Ocean science and protect this vital natural asset.
Climate change and the nuclear threat are raising concerns about our planet’s future ability to support human life. If we launch a species survival mission, who should go?
Sea ice extent in July 2023 has been around 10% below last year’s record low for the month.
More trouble in Antarctica: the extent of frozen seawater fastened to the coast (called landfast ice) hit a record low in March 2022. If this trend persists, the consequences could be catastrophic.
Scientists have detected a 30% slowdown of the deep ocean currents that form in Antarctica, with profound consequences for Earth’s climate, sea level and marine life.
