London: British researchers have debunked a long-prevailing theory that ocean acidification from the asteroid impact that killed the dinosaurs caused the extinction of marine molluscs.
The team from University of Southampton found that the acidification levels produced were too weak to have caused the disappearance of the calcifying organisms 66 million years ago when the asteroid hit the Earth.
The next question though is the really interesting one. Will predicted acidification from human emissions lead to a similar exitnction or not? For the predictions that it will depend to some extent upon the assumption that it did. And if it didn’t then what of the prediction?
