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.
