A meteorite plummeting to Earth is only part of the story, a new study suggests. Climate change triggered by massive volcanic eruptions may have ultimately set the stage for the dinosaur extinction, challenging the traditional narrative that a meteorite alone delivered the final blow to the ancient giants.</p> Fri, 24 Nov 2023 20:11:05 +0000 claire.loewen@mcgill.ca 307487 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/channels/news/experts-guatemala-volcano-eruption-287548 <p>“Rescuers scoured a lava- and ash-ravaged landscape in Guatemala for a third straight day on Wednesday in search of survivors and victims of Fuego volcano’s calamitous eruption, which has killed at least 99 people.” (<a href="https://www.reuters.com/article/us-guatemala-volcano/rescuers-search-for-missing-near-guatemala-volcano-as-death-toll-climbs-idUSKCN1J22LP">Reuters</a>)</p> Thu, 07 Jun 2018 13:43:25 +0000 vincent.allaire@mcgill.ca 43820 at /newsroom /newsroom/don-baker Tue, 26 Feb 2019 16:59:44 +0000 Anonymous 22618 at /newsroom
