Antarctica serves as a critical indicator of climate change

Antarctica serves as a critical indicator of accelerating climate change, according to Rafel Simó, a researcher from the Institute of Marine Sciences (CSIC). The continent provides a unique window into historical climates, as deep continental ice contains atmospheric bubbles from up to a million years ago.

Despite the hostile environment, the region maintains significant marine biodiversity, including whales, orcas, seals, and various fish species supported by microscopic plankton. The Antarctic Treaty, signed in 1959, remains a vital geopolitical framework, ensuring the continent is used exclusively for peaceful purposes and scientific investigation. Recent data suggests some positive trends, such as the gradual healing of the ozone layer.
