Arctic Ocean Litmus Test
Waters around the North Pole are absorbing carbon dioxide at such a rate that they will soon start dissolving the shells of living sea creatures.
The potentially disastrous consequences for the food chain have been highlighted by Professor Jean-Pierre Gattuso of the National Centre for Scientific Research in France.
Their forecasts suggest that by 2018, 10 per cent of the ocean will be corrosively acidic, rising to 50 per cent in 2050. By 2100 the entire Arctic Ocean will be inhospitable to shellfish, they predict.
"Over the whole planet, there will be a threefold increase in the average acidity of the oceans, which is unprecedented during the past 20 million years,"
"corrosively acidic" "dissolving the shells" "threefold increase in the average acidity" - It's going to turn into battery acid!
I can't find his research but an article he is lead author of updated on 3rd October 2009 says the pH of the Oceans was 8.18 in pre industrial times, 8.09 in 1990, projected to be 7.93in 2065 and 7.84 in 2100. So not quite Haighian Acid Bath that the Telegraph science writer suggests.
