Editorial
Expert Opinion is Still Just Opinion, and Not Necessarily the Truth: A wise woman reminds all of us about this most important fact of life.

Subject Index Summary
Carbon Sequestration (Soils): As the CO2 content of the air increases, nearly all of earth's plants respond favorably by increasing their photosynthetic rates and producing greater amounts of biomass. Invariably, this phenomenon leads to greater inputs of carbon to the soil in the form of roots, root exudates and senesced plant material. Much research has been conducted to determine if these biological inputs will increase the carbon sequestering abilities of soils, particularly if air temperatures rise, which has been predicted by some to enhance plant litter decomposition rates to the point that global warming may be exacerbated. Thus, we here summarize research results that have addressed this important subject.

Journal Reviews
Sea Level Consequences of Exceptional Glacial Meltwater Forcing: Does the latter phenomenon ramp up the rate-of-rise of the surface of the global ocean?

The Indo-Australian Monsoon in CMIP3 and CMIP5 Simulations: How well is it represented?

Modelling the Atlantic Multi-decadal Oscillation of the 20th-Century: How have things progressed in going from CMIP3 models to CMIP5 models?

Biological Soil Crusts Sequestering Carbon in Dryland Soils: How do they do it? ... and how much do they do when they do it?

Azooxanthellate Corals in a CO2-Enriched World of the Future: How could they possibly survive without any photosynthetic symbionts?

Embryonic Norway Lobsters in a Warmed and Acidified Ocean: What are the odds of their surviving the worst nightmare of the world's climate-alarmists?

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: Garden Lettuce (Perez-Lopez et al., 2013) and Norway Spruce (Hall et al., 2013).

Major Report
The Positive Externalities of Carbon Dioxide: Estimating the Monetary Benefits of Rising Atmospheric CO2 Concentrations on Global Food Production: Several analyses have been conducted to estimate potential monetary damages of the rising atmospheric CO2 concentration.Few, however, have attempted to investigate its monetary benefits.This study addresses this discrepancy by providing a quantitative estimate of the direct monetary benefits of atmospheric CO2 enrichment on both historic and future global crop production.Results indicate that the annual total monetary value of the increase in the air's CO2 content (since the inception of the Industrial Revolution) for world crop production grew from about $18.5 billion in 1961 to over $140 billion by 2011, reaching the staggering sum of $3.2 trillion over the 50-year time period from 1961-2011.And projecting the monetary value of this positive externality forward in time reveals that it will bestow an additional $9.8 trillion on crop production between now and 2050.

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.
