Key Takeaways
- The Antarctic Ice Sheet is losing approximately 135 billion tons of ice annually, according to NASA data updated in March 2026.
- Greenland’s ice sheet lost 139 gigatonnes of ice in the 2024-2025 hydrological year, as reported by Copernicus Climate Change in April 2026.
- A June 2025 modeling study found the West Antarctic Ice Sheet could face irreversible collapse with just 0 to 0.25°C ocean warming, as cited by Space Daily in June 2026.
- The Thwaites Eastern Ice Shelf is projected to detach from its glacier in 2026, according to scientists associated with the International Thwaites Glacier Collaboration in May 2026.
- Melt rates in channels beneath ice shelves like Fimbulisen can increase by an order of magnitude locally due to trapped warm ocean water, a finding from an iC3 Polar Research Hub study in May 2026.
