Ocean acidification is another environmentalist manufactured scare story. There is extremely little likelihood the ocean could possibly become acidified – or ever has, and yet the hype is being wound up like clockwork and the subject is due to feature in the latest IPCC report as well as the Rio bean feast. A paper at www.sciencenews.org/view/generic/id/341465 … claims ocean acidification was responsible for an extinction event that took place 252 million years ago. The implication, by association with doomsaying, is that ocean acidification is happening in the modern world and could produce equally devastating catastrophe. A paleobiologist at Stanford University claims the Great Dying at the end of the Permian hit marine creatures hardest – and perhaps it did. So what. Putting it into perspective, a palaeontologist at the University of Leeds says the records are 'too crude' to reveal the timing of the 'calcium shift' and light calcium could well have come from the shells of creatures wiped out by other means. The data is showing that a lot of skeletal invertebrae died out – and that is the effect rather than the cause. Have the team at Stanford sold their soul?
