How Corals Are Able to Tolerate Significant Seawater Acidification: It's a complex process; but it appears to be capable of doing what needs to be done.

Subject Index Summary
Nitrous Oxide: Nitrous oxide (N2O) is an influential greenhouse gas, with a global warming potential approximately 300 times that of CO2 on a per-molecule basis; and, therefore, understanding the factors controlling the concentration of this gas in the atmosphere, and how its sources and sinks vary with changes in climate and other factors, has been a topic of great concern among the scientific community. Consequently, in this Summary we review important research that has been conducted on this topic, beginning with a discussion of studies examining how increases in atmospheric CO2 might modify the release of N2O into the atmosphere.

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.
