Journal Reviews
Urban Heat Islands of Small Towns: An empirical study of urban heat island effects in cities of various sizes in North America and Europe reveals that towns with as few as 1,000 inhabitants create a warming of the air within them that is over twice as great as the background warming believed to have occurred since the end of the Little Ice Age, casting a pall of uncertainty upon climate alarmist estimates of the degree of global warming experienced over the past century.

The Medieval Warm Period and Little Ice Age in Southern Africa: Archaeological Evidence: Archaeological evidence from southern Africa argues strongly for a Medieval Warm Period in that part of the world that was warmer than it is today, in contradiction of the claim of modern climate alarmists who are attempting to paint the current temperature of the earth as unprecedented in the past millennium.

Effects of Elevated CO2 and Nitrogen on Spruce Needle Carbohydrates: Elevated CO2 induced seasonal photosynthetic down regulation in spruce tree needles by increasing needle glucose contents.

Photosynthetic Response of a Desert Plant to Elevated CO2: A 53% increase in atmospheric CO2 concentration (from 360 to 550 ppm) increased rates of net photosynthesis in the perennial desert shrub known as creosote (Larrea tridentata) by 80 to 100%, depending on soil moisture conditions.  Plant water-use efficiency was similarly increased.

Effects of Elevated CO2 on Slug Herbivory: Terrestrial slugs did not exhibit increased consumption when fed plant material grown for five years at atmospheric CO2 concentrations of 650 as opposed to 350 ppm.  They did, however, display a marginally significant preference for leguminous vs. non-leguminous species when fed a mixture of these vegetative types.
