Ocean acidification to threaten sea life, worsen climate change say 2 new studies, reports Bryan Walsh at Time Magazine. Oceans are absorbing a large portion of the CO2 emitted into the atmosphere—in fact, oceans are the largest single carbon sink in the world, dwarfing the absorbing abilities of the Amazon rainforest. But the more CO2 the oceans absorb, the more acidic they become on a relative scale, because some of the carbon reacts within the water to form carbonic acid. Although this is a slow-moving process, the acidification is occurring rapidly on a geologic timescale, and it will make the oceans much less hospitable to many forms of marine life, much more difficult to adapt to, and may actually to serve to amplify overall warming. Besides slowing marine shell and skeletal formation, increasing acidification attacks fish nerves, causing confused behavior, adds Katie Valentine at Climate Progress. Coral reefs could disappear by 2100. Acidification also reduces marine emissions of sulfur, the largest natural sulfur source to the air. These sulfur emissions block sunlight, creating a slight cooling. So, declining sulfur emissions will help accelerate global warming.
Join the swelling numbers of voters TELLING Congress they’ll vote for Clean Energy candidates here: http://signon.org/sign/we-are-the-clean-99?source=c.em.cp&r_by=487176 . This is an ongoing campaign (the next Congressional election is in less than 2 years!) so please, spread the word. It’s our way of telling Congress that a strong clean energy voting bloc is out there. This is how YOU can make a difference.
