COP29 Video of the Week: Polar Oceans – Triple Threat of Acidification, Warming and Freshening

The Arctic and Southern Oceans are crucial components of the global climate system. Their unique ecosystems are under serious threat from warming, acidification, freshening and ice loss. Polar oceans are already experiencing changes in chemistry, and continued warming is leading to population range shifts, changes in food webs, ecosystems, fisheries, and climate regulation. Speakers highlighted the latest science and discussed the wider societal and political impacts, while emphasizing the need to raise ambition for reducing emissions. Dr. Matt Frost from Plymouth Marine Laboratory (PML) moderated the session. Presenters included Paul Irngaut, Inuit Circumpolar Council (ICC) Canada, Vice-President of Nunavut Tunngavik Inc; Dr. Helen Findlay, PML; Dr. Lorenz Meire, Greenland Institute of Natural Resources; Dr. Alyce Hancock, Southern Ocean Observing System; and Pam Pearson, International Cryosphere Climate Initiative.
