AGP Executive Report
Last update: 9 hours agoIce-sheet Science: Satellite observations from 2019–23 challenge models of runaway ice loss: cliffs under 100 metres rarely calved, though taller cliffs retreated faster than predicted. The study examined more than 15,000 cliffs in Greenland and Antarctica. Greenland’s Seabed: Parliament unanimously backed a proposal to halt deep-sea mining exploration and extraction through 2029. The government must still draft legislation; fishers and WWF Greenland welcomed the move, citing risks to marine habitats and livelihoods. Resource Pressure: Trump’s claim that major oil, gas and mineral exploration is about to begin remains short on specifics. Greenland controls its own mineral permits, and harsh conditions, limited infrastructure and local opposition pose major hurdles. Satellite Watch: New Sentinel-3C data include elevation measurements of the Greenland Ice Sheet, adding to tools for tracking changes across the cryosphere. Arctic Sea Ice: A study using ancient ocean-sediment clues suggests future winter sea-ice loss may be about one million square kilometres greater than earlier projections.
