Unless CO2 emissions drop significantly, global warming by 2500 will make the Amazon barren, the American Midwest tropical, and India too hot to live in, according to a team of international scientists.</p> Tue, 12 Oct 2021 22:30:51 +0000 shirley.cardenas@mcgill.ca 279560 at /newsroom /newsroom/channels/news/volcanic-co2-emissions-helped-trigger-triassic-climate-change-321564 <p>A new study finds volcanic activity played a direct role in triggering extreme climate change at the end of the Triassic period 201 million year ago, wiping out almost half of all existing species. The amount of carbon dioxide released into the atmosphere from these volcanic eruptions is comparable to the amount of CO<sub>2</sub> expected to be produced by all human activity in the 21st century.</p> Tue, 14 Apr 2020 14:54:46 +0000 shirley.cardenas@mcgill.ca 208241 at /newsroom /newsroom/article/mcgill-dans-la-ville/transformer-lelectricite-en-gaz-naturel <p>Les énergies renouvelables comme l’éolien et le solaire sont appelées à gagner en importance dans la lutte contre les changements climatiques; toutefois ces solutions de remplacement ne sont pas sans écueils, l’un d’eux étant le stockage. Et si on pouvait transformer l’électricité en gaz naturel renouvelable? C’est exactement ce que propose de faire une équipe de chercheurs de l’Université ƽÌØÎå²»ÖÐ, en collaboration avec l’entreprise Xebec Adsorption.</p> Wed, 17 Oct 2018 15:06:32 +0000 Justin Dupuis 90464 at /newsroom /newsroom/channels/news/geophysics-could-slow-antarctic-ice-retreat-256655 <p> Gravitational effects, variations in Earth structure could damp rise in global sea levels Tue, 10 Nov 2015 15:17:50 +0000 laurie.devine@mcgill.ca 24688 at /newsroom
