University of California - Santa Barbara Marine scientists have long understood the detrimental effect of fossil fuel emissions on marine ecosystems. But a group led by a UC Santa Barbara professor has found a point of resilience in a microscopic shelled plant with a massive environmental impact, which suggests the future of ocean life may not be so bleak. As fossil fuel emissions increase, so does the amount of carbon dioxide oceans absorb and dissolve, lowering their pH levels. "As pH...

Coccolithophores are microscopic marine plants that convert carbon dioxide into chalk. It was thought that rising C02 and more acid oceans would curb their activity. Instead they are booming - and fighting global warming. For hundreds of millions of years, marine creatures of all shapes, sizes and descriptions have gone about the daily business of converting calcium ions dissolved in seawater into the hard shells and skeletons that are so reminiscent of a trip to the seaside. Many of these...
