[font size=3]SAN FRANCISCO -- A year-long experiment on tiny ocean organisms called coccolithophores suggests that the single-celled algae may still be able to grow their calcified shells even as oceans grow warmer and more acidic in Earths near future.
The study stands in contrast to earlier studies suggesting that coccolithophores would fail to build strong shells in acidic waters. The worlds oceans are expected to become more acidic as human activities pump increasing amounts of carbon dioxide into the Earths atmosphere.
But after the researchers raised one strain of the Emiliania huxleyi coccolithorphore for over 700 generations, which took about 12 months, under high temperature and acidified conditions that are expected for the oceans 100 years from now, the organisms had no trouble producing their plated shells.
At least in this experiment with one coccolithophore strain, when we combined higher levels of CO[font size="1"]2[/font] with higher temperatures, they actually did better in terms of calcification. said Jonathon Stillman, associate professor of biology at San Francisco State University, who along with Ed Carpenter, professor of biology, and Tomoko Komada, associate professor of chemistry, led a team of researchers at the Universitys Romberg Tiburon Center for Environmental Studies. The research was performed by postdoctoral scientist Ina Benner, masters students Rachel Diner and Dian Li and postdoctoral scientist Stephane Lefebvre.

(29,798 posts)2. I wouldn't go that far.
What it might mean, though, is that the climate warming related major level marine extinction events we see in the fossil record wont occur until the methane clathrates erupt on a wide scale.

IE the next several centuries to millenia.
It does jack shit for the billions of humans that climate change will kill in the short term this century.
