Ocean Acidification Database
The latest addition of peer-reviewed data archived to our database of marine organism responses to atmospheric CO2 enrichment is Serpent Star [Ophiura ophiura] (Wood et al., 2010; net calcification from regenerated arms 40 days after exposure to low pH). To access the entire database, click here.

Plant Growth Database
Our latest results of plant growth responses to atmospheric CO2 enrichment obtained from experiments described in the peer-reviewed scientific literature are: Indiangrass (Lee et al., 2011) and Little Bluestem (Lee et al., 2011).

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.
