The BBC Science & Environment section published today a highly informative 3-part series on the acidification of our oceans through CO2 emissions and the likely consequences for marine life. This is part one of the series; part two and three follow below this post.
Acidic seas fuel extinction fears
By Roger Harrabin
Environment analyst, BBC News
Carbon dioxide emissions from human activities are acidifying the oceans and threaten a mass extinction of sea life, a top ocean scientist warns.
Dr Carol Turley from Plymouth Marine Laboratory says it is impossible to know how marine life will cope, but she fears many species will not survive.
Since the Industrial Revolution, CO2 emissions have already turned the sea about 30% more acidic, say researchers.
It is more acidic now than it has been for at least 500,000 years, they add.
The problem is set to worsen as emissions of the greenhouse gas increase through the 21st Century.
