Seas Turn to Acid as They Soak Up CO2
Oct 05, 2008
The Bay of Naples is renowned for its breathtaking beauty and glittering clear waters. For centuries, tourists have flocked to the region to experience its glories.
But beneath the waves, scientists have uncovered an alarming secret. They have found streams of gas bubbling up from the seabed around the island of Ischia. 'The waters are like a Jacuzzi - there is so much carbon dioxide fizzing up from the seabed,' said Dr Jason Hall-Spencer, of Plymouth University. 'Millions of litres of gas bubble up every day.'
The gas streams have turned Ischia's waters into acid, and this has had a major impact on sea life and aquatic plants. Now marine biologists fear that the world's seas could follow suit.
'Every day the oceans absorb more than 25m tonnes of carbon dioxide from the atmosphere,' said Hall-Spencer. 'If it were not for the oceans, levels of greenhouse gases in the atmosphere would be far higher than they are today and the impact of climate change would be far worse. However, there is a downside: it is called ocean acidification.'
Scientists calculate that the seas are absorbing so much carbon dioxide that they are 30 per cent more acidic than they were at the start of the Industrial Revolution. The change is three times greater and has happened 100 times faster than at any other time during the past 20 million years.
Tomorrow hundreds of scientists will gather in Monaco for the 'Second International Symposium on the Ocean in a High CO2 World'. One focus of debate is likely to be the Plymouth study. The seas off Ischia - which are affected by carbon dioxide from volcanic activity - offer a first-class opportunity to investigate what might happen in the next few decades.
Scientists found that in Ischia's highly acidic water:
* Biodiversity of plants and fish has dropped by 30 per cent
* Algae vital for binding coral reefs have been wiped out
* Invasive 'alien' species, such as sea-grasses, are thriving
* Coral and sea urchins have been destroyed, while mussels and clams are failing to grow shells.
The conference will also tackle the dangers posed to fish larvae, which are sensitive to high levels of acid, as well as the threat to commercial fish stocks.
'Many developing countries have seafood as their prime source of food,' said Dr Carol Turley, of the Plymouth Marine Laboratory. 'If they lose that, the result could be famine.'
An Urgent Message From Our Co-Founder
Dear Common Dreams reader, It’s been nearly 30 years since I co-founded Common Dreams with my late wife, Lina Newhouser. We had the radical notion that journalism should serve the public good, not corporate profits. It was clear to us from the outset what it would take to build such a project. No paid advertisements. No corporate sponsors. No millionaire publisher telling us what to think or do. Many people said we wouldn't last a year, but we proved those doubters wrong. Together with a tremendous team of journalists and dedicated staff, we built an independent media outlet free from the constraints of profits and corporate control. Our mission has always been simple: To inform. To inspire. To ignite change for the common good. Building Common Dreams was not easy. Our survival was never guaranteed. When you take on the most powerful forces—Wall Street greed, fossil fuel industry destruction, Big Tech lobbyists, and uber-rich oligarchs who have spent billions upon billions rigging the economy and democracy in their favor—the only bulwark you have is supporters who believe in your work. But here’s the urgent message from me today. It's never been this bad out there. And it's never been this hard to keep us going. At the very moment Common Dreams is most needed, the threats we face are intensifying. We need your support now more than ever. We don't accept corporate advertising and never will. We don't have a paywall because we don't think people should be blocked from critical news based on their ability to pay. Everything we do is funded by the donations of readers like you. When everyone does the little they can afford, we are strong. But if that support retreats or dries up, so do we. Will you donate now to make sure Common Dreams not only survives but thrives? —Craig Brown, Co-founder |
