Algal Symbionts Appear to Determine Responses of Calcifying Organisms to Ocean Acidification: And if one type won't help them, perhaps another will???

Subject Index Summary
Peatlands: Earth's peatlands contain a vast amount of sequestered carbon, about as much, in fact, as that contained in the entire atmosphere. As a result, they are vital elements of the planet's carbon cycle and have the potential to significantly impact its climate. In this summary, we briefly review the findings of several papers that come to bear upon this topic.

Climate Change Reconsidered
The 2011 Interim Report of the Nongovernmental International Panel on Climate Change: We provide a link to this report as a courtesy and encourage all to download and read it. The 2011 Interim Report presents an overview of the research on climate change that has appeared since publication of Climate Change Reconsidered: The 2009 Report of the Nongovernmental International Panel on Climate Change. Research published before 2009 was included if it did not appear in the 2009 report or provides context for the new research. Nearly all of the research summarized here appeared in peer-reviewed science journals.
