La Camera dei Deputati argentina ha approvato giovedì mattina una riforma della legge sui ghiacciai con 137 voti favorevoli, 111 contrari e 3 astenuti. La modifica consente attività estrattive come l'estrazione mineraria in aree precedentemente protette, scatenando la reazione di ambientalisti e cittadini. Oltre 300.000 persone hanno aderito a un ricorso collettivo per incostituzionalità e il governatore della provincia di La Pampa ha presentato un'istanza cautelare giudiziaria.
A new study shows Alaska's glaciers respond sharply to warmer summers. Researchers tracked more than 3,000 glaciers using radar satellites and found that each 1 degree Celsius rise in average summer temperature adds roughly three weeks to the melt season.

Glaciers in the Pamir mountains of central Asia lost a record amount of ice last year after decades of stability. Researchers link the sudden melt to prolonged extreme heat across the region.
A meltwater lake on Greenland's 79°N Glacier, formed in 1995, has undergone sudden drainages that are fracturing the ice in unusual triangular patterns. These events, accelerating in recent years, raise concerns about the glacier's long-term stability amid warming temperatures. Scientists are studying whether it can recover from these disturbances.

In May 2025, a massive glacier collapse destroyed the village of Blatten in the Swiss Alps, but careful monitoring allowed the evacuation of nearly all residents. One man who refused to leave was killed in the disaster. The event highlights growing risks to mountain communities amid climate change.
A new study indicates that the Thwaites Glacier in Antarctica has crossed an irreversible tipping point, potentially accelerating global sea level rise. Researchers analyzed decades of satellite data to reach this conclusion. The findings highlight the urgent risks posed by climate change in polar regions.

Swiss glaciers continued their rapid decline in 2023, shedding 6.3% of their remaining volume amid high temperatures and low snowfall. This marks the second-largest annual loss on record, following a 6.7% drop in 2022. Glaciologists warn that the ongoing melt threatens water resources and ecosystems in the Alps.
