Global warming has triggered an array of apocalyptic scenarios for future generations, from worsening drought, storms and floods to melted icesheets and rising seas.
Now a new study, published on Tuesday and coinciding with the UN climate talks in Paris, adds to the grim tableau: the risk that warming at the far end of the scale could rob our planet of oxygen.
“We have identified another possible consequence of … global warming that can potentially be more dangerous than all others,” say a pair of scientists from Britain’s University of Leicester.
Their study, based in the peer-reviewed journal the Bulletin of Mathematical Biology, is based on a computer model of phytoplankton, the microscopic sea plants which produce about two-thirds of the oxygen in the atmosphere.
