A group of five South African students, including 17-year-old Luke Boswell from Gqeberha, recently returned from a transformative expedition to Deep Field Antarctica. The programme, led by adventurer Riaan Manser, aims to inspire young people to address environmental challenges through practical action. Participants describe profound shifts in their understanding of climate change and personal growth.

A city-sized Antarctic iceberg known as A23a has formed a vast pool of meltwater on its surface, raising concerns it may soon break apart. Satellite imagery reveals an unusual raised ice rim holding billions of litres of water, resembling an oversized swimming pool. Scientists suggest this pooling could accelerate the berg's fragmentation in warmer waters.

Spinning underwater vortices, known as submesoscale storms, are responsible for 20 percent of the ice melt under the Thwaites glacier's ice shelf in Antarctica. These features trap warm deep water beneath the ice, accelerating melting in a feedback loop. As the climate warms, they could intensify and contribute to greater sea level rise than previously anticipated.

A glacier on the Eastern Antarctic Peninsula has experienced the quickest ice loss ever documented in modern times. Hektoria Glacier shortened by nearly half its length in just two months in 2023, shedding eight kilometers of ice. This rapid collapse, driven by its below-sea-level ice plain, raises concerns about accelerated sea level rise from larger Antarctic glaciers.

Chile's Hydrographic and Oceanographic Service of the Navy (Shoa) ruled out any tsunami generation on national coasts following a 5.2 magnitude earthquake in the Antarctic Sea. The epicenter was located 289 kilometers northwest of Presidente Eduardo Frei Montalva Air Base in the Antarctic Peninsula.

Russian authorities have accused Antarctic marine biologist Dr. Leonid Pshenichnov of high treason for his work on marine protected areas that could hinder Russia's resource ambitions in the region. The 70-year-old Ukrainian, arrested in occupied Crimea, was set to represent his country at an international conservation meeting. The case has raised alarms about scientific freedom and Russia's compliance with Antarctic treaties.
