Oceans acidifying at unprecedented rate, says chief scientist

Blue and Green: Sir Mark Walport, the UK governments chief scientist, has warned that since the industrial revolution the acidity of the worlds oceans has increased by 25% and is set to rise further -- threatening fish stocks and the natural environment. Today ocean acidification is being driven by manmade carbon emissions, which are often absorbed by the seas. Scientists have observed that the current acidification trend far exceeds historical, naturally occurring trends. Speaking to the BBC, Walport said,...

Can Marine Life Adapt to Worlds Acidifying Oceans?
2014-05-14 17:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Yale Environment 360: As the worlds oceans grow more acidic from increased absorption of atmospheric carbon dioxide, marine scientists are confronting a key question: How well can organisms like mollusks, crustaceans, and corals adapt to these more corrosive conditions? One of the leading authorities in this field is University of California, Santa Barbara marine biologist Gretchen Hofmann. Her work in recent years has shown, in fact, that some sea organisms that build shells do seem to have some ability to acclimate...

Acidifying Oceans Alarm Hundreds of Scientists
2013-11-27 08:25:00| Climate Ark Climate Change & Global Warming Newsfeed
Environment News Service: Climate change is causing the world`s oceans to acidify at rates not seen for the last 55 million years, and the only way to moderate this danger is to reduce human emissions of carbon dioxide, conclude 540 scientists from 37 countries in a new report. Their conclusion is the outcome of the Third Symposium on the Ocean in a High CO2 World that took place in Monterey, California in September 2012. The findings of these experts were presented in a report to the Conference on Climate Change that...

The oceans are heating, acidifying and choking
2013-10-04 21:17:00| Climate Ark Climate Change & Global Warming Newsfeed
New Scientist: We know the oceans are warming. We know they are acidifying. And now, to cap it all, it turns out they are suffocating, too. A new health check on the state of the oceans warns that they will have lost as much as 7 per cent of their oxygen by the end of the century. The cascade of chemical and biological changes now under way could see coral reefs irreversibly destroyed in 50 to 100 years, with marine ecosystems increasingly taken over by jellyfish and toxic algal blooms. The review is a repeat...

Acidifying oceans will heat the planet more
2013-08-25 19:17:00| Climate Ark Climate Change & Global Warming Newsfeed
New Scientist: WHAT goes around comes around. Our greenhouse gas emissions don't just warm the planet, they also acidify the oceans. Now it turns out that the change in ocean chemistry they cause will feed back into the climate, further driving up temperatures. Ocean acidification poses a threat to many marine organisms such as corals the shells of some marine snails are already dissolving. Until now it seemed like this was strictly a problem for marine organisms and the people who depend on them: 'climate...
