by Kelly MACNAMARA Agence France Presse Paris, France (AFP) — The runaway collapse of the West Antarctic Ice Sheet — which would trigger catastrophic sea level rise — is not “inevitable”, scientists said Monday following research that tracked the region’s recent response to climate change. As global temperatures rise, there is mounting concern that warming could trigger so-called tipping points that set off irreversible melting of the world’s massive ice sheets and ultimately lift oceans […]
by Kelly MACNAMARA PARIS, France (AFP) — Scientists have found bits of polystyrene in the guts of tiny, soil-dwelling organisms in the Antarctic, raising concern that microplastics pollution has already “deeply” entered the world’s most remote land-based food systems. While the infiltration of microplastics throughout the oceans is well-known, researchers said their findings provided the first evidence of contamination in the Antarctic terrestrial food chain. “Plastics have therefore entered even some of the most remote […]
SANTIAGO, Chile (Reuters) — Scientists in Chile have discovered molecules in two species of Antarctic flowers that protect the plants from solar radiation and could potentially be used in products such as sunscreen for humans and protection for vulnerable crops. Researchers at the University of Santiago investigating the properties of Antarctic plants grown under controlled conditions found that Colobanthus quitensis (pearlwort) and Deschampsia antarctica (hair grass) could tolerate high levels of ultraviolet radiation. According to […]
