Millennial-Scale Climate Variability During the Holocene: What might have been its cause? ... and what likely was not its cause?

Subject Index Summary
Stomatal Conductance (Agricultural Crops): When the air's CO2 content rises, most plants respond by reducing their leaves' stomatal apertures, through which water vapor exits and carbon dioxide enters during transpiration and photosynthesis, respectively, because with more CO2 in the air, plants don't need to open their stomates as wide as they do at lower atmospheric CO2 concentrations to allow for sufficient inward diffusion of CO2 for use in photosynthesis. And as a result, plants typically exhibit significant reductions in transpirational water loss and smaller yield losses due to the indiscriminate uptake of aerial pollutants, leading to increases in water-use efficiency.

The Modeling of Low-Frequency Rainfall Variability: How close do general circulation models come to matching what is observed in nature?

Simulations of Mediterranean and Northern Africa Precipitation: How well do CMIP5 simulations compare with what is known about the subject?

Carbon-Nitrogen Cycle Models of Forest Responses to Elevated CO2: How well do they represent reality?

A Real-Life Non-Calcifying Anthozoan-Symbiodinium Symbiosis: How does it respond to manipulated ocean acidification conditions?

Plant Growth Database
Our latest result of plant growth responses to atmospheric CO2 enrichment obtained from experiments described in the peer-reviewed scientific literature is for Tobacco (Schaz et al., 2014).

Major Report
New Report from the Nongovernmental International Panel on Climate Change
Climate Change Reconsidered II: Biological Impacts: On March 31, 2014 the fifth in a series of scholarly reports produced by the Nongovernmental International Panel on Climate Change (NIPCC) was released to the public. This new publication represents an independent, comprehensive, and authoritative report on the current state of climate science. We encourage all to read it.

World Temperatures Database
Back by popular demand and upgraded to allow patrons more choices to plot and view the data, we reintroduce the World Temperatures section of our website. Here, users may plot temperatures for the entire globe or regions of the globe. A newly added feature allows patrons the ability to plot up to six independent datasets on the same graph. Try it today. World Temperatures Database.

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.
