Chicxulub impact event As waters become more acidic, the shell-making process requires more energy ( SN: 8/6/16, p.8 ). The Deccan eruptions wreaked havoc in at least part of Antarctica. Analyzing the temperature-dependent chemical makeup of the shells of 29 clamlike bivalves from the continent’s Seymour Island, researchers assembled a roughly 3.5-million-­year record of how Antarctic temperatures changed around the time of the dinosaur extinction. Following the start of the Deccan eruptions and the resulting rise in atmospheric CO2,  local temperatures warmed about 7.8 degrees , scientists from the University of Michigan and University of Florida reported in July in Nature Communications. About 150,000 years later, a second, smaller warming phase coincided with the Chicxulub impact. Both of these warming phases corresponded with high extinction rates on the island . Everyone wasn’t just living happily, and then boom, this impact came out of nowhere,” says study coauthor Sierra Petersen, a geochemist at the University of Michigan. Plants and animals “were already under stress and not having a great day, and this impact happens and pushes them over the top.” Both catastrophic events were major contributors to the extinction event, Petersen argues. “Either one would have caused some extinction, but such a mass extinction is due to a combination of both events.” Noting that some parts of the world were affected by the Deccan eruptions before the impact is not enough to demonstrate that life overall was stressed at the time, says Imperial College’s Morgan. Fossil evidence in many regions suggests that marine life flourished until the impact, she says. But maybe bad luck wasn’t the reason the dinosaurs encountered two devastating disasters at once. Maybe the impact and the volcanism were in cahoots, some researchers propose.
