Pink rocks reveal hidden granite mass under Antarctic glacier

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.
New studies indicate that stronger winds and warming deep ocean water have triggered a sharp decline in Antarctic sea ice since 2016. Previously expanding, the ice reached a record high in 2014 before plummeting to record lows. Researchers link this shift to wind-driven upwelling of circumpolar deep water.

Researchers have analysed a 3-million-year-old ice core from Allan Hills in Antarctica, measuring atmospheric CO2 at 250 parts per million and methane at 507 parts per billion during the late Pliocene. This epoch featured global temperatures about 1°C warmer than today and sea levels up to 25 metres higher. The levels are lower than previous indirect estimates.
A new study reveals that iron from melting West Antarctic ice does not boost algae growth as expected, potentially reducing the Southern Ocean's ability to absorb carbon dioxide. Researchers found that the iron delivered by icebergs is in a poorly usable form for marine life. This discovery challenges assumptions about how ice loss affects climate change mitigation.

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.
An analysis of cracks in Antarctica's Thwaites Glacier over the past 20 years indicates it is nearing a total collapse. Known as the Doomsday Glacier, this rapidly changing ice mass poses uncertainties for global sea level rise predictions.

Scientists from NOAA and NASA have reported that the 2025 ozone hole over Antarctica is the fifth smallest since 1992, when the Montreal Protocol began phasing out ozone-depleting chemicals. Warmer stratospheric temperatures and declining chlorine levels contributed to its limited size. The hole is already breaking apart nearly three weeks earlier than average.
