Predicting the Past: It's Really Not That Difficult: A "hindcast" of the past 140 years of earth's temperature history by one of today's most advanced climate models does no better than analogous studies from the early 1980s; yet the modern model's predictions are hailed as dramatic new proof that "recent global warming is man-made and will continue."

Subject Index Summaries
Carbon Sequestration (Forests): A number of recent experiments have revealed that the ongoing rise in the air's CO2 content should enable forest ecosystems to sequester ever-greater amounts of carbon, even in the face of potential concurrent global warming.

Temperature As a Cause of Coral Bleaching: Gradual global warming is often blamed for recent coral bleaching events.  However, both high and low water temperatures, as well as rapid temperature change in either direction, can cause corals to suffer and die, as can a whole host of other phenomena.  Hence the story is much more complicated than what is typically claimed by climate alarmists.

Current Journal Reviews
A Century of Climate Change in the Central United States: After analyzing pertinent data from the U.S. Historical Climatology Network, the authors of this study decide there has been no significant change in central U.S. climate over the past hundred years.

Landfalling Atlantic Basin Hurricanes: Climate-alarmist theory says yes; real-world data say no.

Long-Term Growth Response of Ponderosa Pine Trees to Elevated CO2 and Nitrogen: Ponderosa pine seedlings rooted in the ground within open-top chambers exhibited sustained CO2-induced increases in growth even at low soil nitrogen contents.

Effects of Elevated CO2, Temperature, and Soil Nitrogen Content on Growth and Root Exudation of Black Locust: In a 100-day growth chamber experiment, elevated air temperature, soil nutrient content and atmospheric CO2 concentration increased total seedling biomass and root exudation in the nitrogen-fixing black locust tree.

Effects of Elevated CO2 and O3 on Potato Tubers: Although elevated CO2 significantly increased tuber yield in potato early in the growing season, yield increases were not apparent at final harvest in this anomalous experiment that produced results contrary to those of the vast majority of all related prior studies.
