A Dubious Climate History Lesson: Our analysis of a recent article on global warming produced by The Economist reveals it to be woefully out of step with climatic reality.

Solar Forcing of Climate: A Means of Amplification?: An exercise in simultaneous solar dynamo and earth climate modeling demonstrates that the typical frequencies of each system may sometimes resonate to greatly amplify climate forcing by solar activity, thereby demonstrating that weak solar signals can indeed be responsible for the many major climatic changes with which they are highly correlated.

The Medieval Warm Period and Little Ice Age in New Zealand: Stalagmite Evidence: A study of oxygen isotopes in a stalagmite from a cave in New Zealand reveals that the Medieval Warm Period and Little Ice Age were, in the words of the authors, "not just a local European phenomenon," thereby contradicting recent climate-alarmist claims to the contrary.

Elevated CO2 Delays Leaf Senescence in Oak Trees: Elevated CO2 delayed senescence in leaves of Quercus myrtifolia, as indicated by direct measurements of leaf chlorophyll content, nitrogen content, and rubisco activity.

Elevated CO2 Reverses Negative Impact of Global Warming in Model Simulations: General circulation models of the atmosphere predicted changes in air temperature and precipitation in the southeaster United States that led to projections of decreases in soybean and peanut yields there in the year 2020.  However, when the yield-enhancing effects of elevated CO2 were included in the analyses, yields of both crops increased.

Pine Seedlings Out-Compete Weeds at High CO2: Elevated CO2 increased loblolly pine seedling biomass under well-watered and water-stressed conditions, even when growing in competition with herbaceous weeds.  Furthermore, elevated CO2 did not increase total weed biomass, but it did cause a non-significant increase in the presence of C3 as opposed to C4 weed species.
