New model shows warm water undercuts Thwaites, doubling sea-level risk
Warm ocean water is now known to be penetrating miles beneath Thwaites Glacier, doubling previous sea-level risk projections. Even without additional global warming, this new model shows the glacier could add 30 millimeters to sea levels by 2100, with a 60% chance of losing its critical stabilizing ridge. This is empirical evidence that ocean intelligence must guide our climate indicators. Understanding drives protection.

Switzerland's glacier loss accelerates to nearly 20% in five years
Switzerland's glaciers lost more than 5% of their ice volume in 2026 alone, pushing the five-year total to nearly 20%. Some of the country's most famous glaciers recorded their worst melting ever, while smaller ones vanished entirely. Unusually snowless winters and extreme summer heat are driving this measurable, empirical loss. These are not abstract climate indicators, they are calibrated, real-time signals of systemic change.
27 meters of ice loss measured across 50 years in reference glaciers
Twenty-seven meters of water equivalent. That is the cumulative ice loss measured across the World Glacier Monitoring Service's reference glaciers since 1970, a slab nearly 100 feet thick sliced from the top of each one. Glacier mass balance is a direct, empirical climate indicator. This is not a projection; it is validated, longitudinal data. Understanding drives protection.
