La plataforma de hielo del glaciar Thwaites está cerca de desprenderse en la Antártida

El glaciar Thwaites de la Antártida está perdiendo su plataforma de hielo oriental a medida que grandes fracturas se extienden por toda la estructura flotante. Este fenómeno amenaza con acelerar el flujo del glaciar y contribuir al aumento del nivel del mar a nivel mundial en las próximas décadas.

La plataforma de hielo oriental de Thwaites abarca unos 1500 kilómetros cuadrados y tiene 350 metros de espesor. Las observaciones satelitales muestran que la plataforma se está fracturando rápidamente alrededor de su punto de anclaje y a lo largo de la línea de contacto donde el glaciar se encuentra con el mar. Las velocidades de flujo se han triplicado desde enero de 2020 y alcanzaron poco más de 2000 metros por año en enero de 2026, registrándose una mayor aceleración en los meses siguientes.

Bright pink granite boulders on Antarctica's Hudson Mountains have unveiled a massive buried granite body beneath Pine Island Glacier. The structure measures nearly 100 km wide and 7 km thick. Researchers linked the rocks, dated to 175 million years ago, to this subglacial feature using gravity surveys.

Antarctica's Hektoria Glacier lost 15 miles of length in just 15 months, marking the fastest retreat of grounded ice observed in modern times. The collapse unfolded between early 2022 and spring 2023 on the eastern Antarctic Peninsula.

In 2023, Hektoria Glacier on Antarctica's Eastern Peninsula retreated eight kilometers in just two months, marking the fastest such event recorded. Nearly half of the glacier broke apart due to its position over a flat underwater bedrock. The discovery, detailed in a new study, highlights vulnerabilities in other Antarctic ice features.

Gases from hot springs in central Zambia show signs of mantle fluids rising to the surface, suggesting an early-stage continental rift. Researchers say this could mark the start of a new tectonic plate boundary. The findings come from samples collected in the Kafue Rift.

A major Atlantic Ocean current system that regulates global climate has been slowing down for nearly 20 years. New research provides direct evidence of the decline across a wide area of the North Atlantic.

New data from the European Space Agency's Swarm satellites reveal that the South Atlantic Anomaly, a weak spot in Earth's magnetic field, has grown by nearly half the size of continental Europe since 2014. A region southwest of Africa is weakening even faster in recent years. This expansion highlights unusual activity in Earth's molten outer core.
