Rise in ocean acidity makes fish anxious, study finds

LA Times: Ocean acidification could alter the behavior of fish and make them more anxious, a new study says. The finding came in an experiment by researchers interested in the neurological effects of the shift in the chemistry of seawater that is happening as the ocean takes up carbon dioxide that has built up in the Earth's atmosphere from human activity. In a laboratory, scientists put one group of young rockfish, a common species along the California coast, in normal seawater and put another group...

Islands Business: Climate change and tourism challenges and opportunities took center stage at yesterdays opening of a three-day summit that brought Micronesian presidents and governors to Saipan. The 19th Micronesian Chief Executives Summit also hope that Guam Governor Eddie B. Calvos recent appointment to the presidential task force on climate preparedness and resilience would bring to the fore the tiny islands huge challenges. One by one, presidents and governors shared their concerns about climate change...

Storing Carbon in Deep Ocean Rocks Could Reduce Climate Threats

Nature World: Scientists from the University of Southampton claim to have found a possible solution to the ever-increasing threat of carbon dioxide in the atmosphere: store it in particular locations far beneath the ocean. Southampton researchers have identified five potential off-shore regions near Australia, Japan, Siberia, South Africa and Bermuda that they say have the geological features suitable for safely storing large volumes of carbon for centuries. While the movement to use more sustainable and...

Beyond Shellfish, Ocean Acidification is Bad for People

LiveScience: here's a predictable arc to many environmental debates. Step 1: Scientists observe a change in the natural world due to human activity. Step 2: A discussion ensues about what this change might mean for the natural world. Will it challenge the prosperity, or even the survival, of this or that species of plant or animal? This phase of the debate is well underway before we finally arrive at Step 3. Step 3: What does this observed change mean for people?That last one is usually the prerequisite for...

Arctic Ocean: Carbon Sink or Carbon Source?
2013-12-04 18:55:00| Climate Ark Climate Change & Global Warming Newsfeed
EcoWatch: For the past three decades, as the climate has warmed, the massive plates of sea ice in the Arctic Ocean have shrunk: in 2007, scientists observed nearly 50 percent less summer ice than had been seen in 1980. While the Arctic Ocean as a whole seems to be storing more carbon than in previous years, the increase in carbon sink capacity may not be as large as scientists predicted. Photo credit: NASA`s Aqua satellite shows the receding Arctic sea ice, Sept. 3, 2010. Dramatic changes in ice cover...
