Antarctica
By Linda GIVETASH Paris (AFP) - Plusieurs colonies de manchots empereurs ont encore vu leurs poussins périr en 2023 en raison de la fonte record de leur banquise d'Antarctique, liée au réchauffement climatique, selon une étude publiée jeudi. La baisse record de la banquise en 2023 a contribué à la deuxième pire année de mortalité des poussins depuis le début des observations en 2018, selon le recensement de l'observatoire British Antarctic Survey. Ce nouveau constat suit l'"échec catastrophique de la reproduction" en 2022 et menace de faire baisser la population à long terme, a déclaré à l'AFP...

Washington (AFP) - The sea ice around Antarctica likely had a record low surface area when it was at its maximum size this winter, a preliminary US analysis of satellite data showed Monday. As the southern hemisphere transitions into spring, the US National Snow and Ice Data Center (NSIDC) said in a statement that Antarctic sea ice had only reached a maximum size of 16.96 million square kilometers (6.55 million square miles) this year, on September 10. The ice pack typically reaches its largest size during the colder winter months, so the September 10 reading will likely remain this year's max...

Paris (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 enough to drastically redraw the world map. New research published Monday suggests a complex interaction of factors affecting the melting of the West Ant...
