Indiana University researchers find Earth may be home to 1 trillion species

BLOOMINGTON, Ind. — Earth could contain nearly 1 trillion species, with only one-thousandth of 1 percent now identified, according to a study from biologists at Indiana University. The estimate, based on the intersection of large datasets and universal scaling laws, appears today in the Proceedings of the National Academy of Sciences. The study’s authors are Jay T.

Oceans Facing Carbon Rates Which Spurred Mass Die-Off 250 Million Years Ago

In case you weren’t already worried about the current and rapid acidification of the world’s oceans, a new report by leading scientists finds that this very phenomenon is to blame for the worst mass extinction event the planet earth has ever seen—approximately 252 million years ago. The findings, published this week in the journal Science by University of Edinburgh researchers, raise serious concerns about …

Greatest mass extinction driven by acidic oceans, study finds

Changes to the Earth’s oceans, caused by extreme volcanic activity, triggered the greatest extinction of all time, a study suggests. The event, which took place 252 million years ago, wiped out more than 90 per cent of marine species and more than two-thirds of the animals living on land. It happened when Earth’s oceans absorbed huge amounts of carbon dioxide …
