waiting with bated breath

Now a new study, published 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.

“The message from this study is that there may be another disaster approaching us as a consequence of global warming, and it may be much worse than all other consequences identified previously,” co-author Sergei Petrovskii told AFP.

“There may be very little warning signs before the disaster actually happens… but once the critical threshold is passed (as estimated at 6 C), then the catastrophe will develop fast,” he explained by email.
