By 2100, we could be heading towards a loss of life in our oceans that rivals some of the largest extinction events in Earth's history if we don't continue to tackle the climate catastrophe, new modeling warns. But "it is not too late to enact the reductions in greenhouse gas emissions needed to avoid a major extinction event," Princeton geoscientists Justin Penn and Curtis Deutsch explain in their paper. Using modeling calibrated against ancient fossil records, they predict the consequences of runaway climate change on marine animals and provide a plausible explanation for an enduring ocean mystery in the process. - Science Alert
