A new study shows that channels beneath Antarctic ice shelves can trap warm ocean water and accelerate melting from below. Researchers focused on the Fimbulisen Ice Shelf in East Antarctica and found that this process may make even cold regions more vulnerable. The findings suggest current climate models could underestimate future sea level rise.

Researchers have determined that a unusual gravity hole beneath Antarctica formed due to slow movements of rock deep inside Earth over millions of years. The anomaly strengthened between 50 and 30 million years ago, coinciding with changes in the continent's climate. This discovery provides insights into how Earth's interior influences surface conditions like sea levels and ice sheets.

New research from Rutgers University reveals that meltwater from Antarctic ice shelves contributes far less iron to surrounding ocean waters than scientists had assumed. Instead, most iron originates from deep ocean water and continental sediments. The findings challenge expectations about iron fertilization and its role in carbon absorption.

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.
