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.


Editorial
The Real Human Impacts on the Corals of Almirante Bay, Panama: How do they compare with the imagined impacts that climate alarmists decry most vociferously?

Subject Index Summary
Medieval Warm Period (North America: Canada Plus): Climate alarmists claim that rising atmospheric CO2 concentrations due to the burning of fossil fuels, such as coal, gas and oil, have raised global air temperatures to their highest level in the past one to two millennia. In this summary this contention is evaluated as it pertains to Canada and other regions north of the lower 48 United States of America.

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: Larch Hybrid (Watanabe et al., 2013) and Robusta Coffee (Ramalho 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.
