Current Editorial
Volunteerism: The Only Way to Fight Global Warming: There is absolutely no need for the enlightened few to force the rest of us to do their bidding in the battle to save the world from our profligate ways of producing and using energy.  Even if they are wrong, we will do their bidding anyway.  And we have their testimony to prove it.

Subject Index Summaries
Boreholes: Borehole temperature logs reveal that much of the 0.7 to 1.0įC warming of the past five centuries occurred prior to the major buildup of atmospheric greenhouse gases.

Decomposition (Agricultural Crops): As the airís CO2 content rises, most agricultural crops will increase their biomass and return greater amounts of litter to the soils in which they grew, following senesce and post-harvest cultural practices.  Does that mean more carbon will be sequestered in those soils?

Current Journal Reviews
20th Century Trends in Canadian Precipitation: Computer models often suggest an increase in the frequency and strength of extreme precipitation events as a result of CO2-induced global warming; and in lieu of the claim of unprecedented warming over the 20th century, a high-latitude country such as Canada (where these effects are predicted to be most strongly expressed) should be in a world of hurt.  Is it?

20th Century Trends in Southern African Rainfall: Computer models often suggest an enhanced hydrologic cycle as a result of CO2-induced global warming.  However, rainfall in southern Africa appears to have been influenced but little, if at all, by the historical rise in the atmospheric concentration of this purported greenhouse gas.

Effect of Warming on Temperature Variability in Switzerland: Climate alarmists predict global warming will produce more variable weather.  Real-world data, on the other hand, tell a much different story.  This report from Switzerland is but one of many examples of what actual measurements reveal about the subject.

Effects of Elevated CO2 on Two Mojave Desert Plants: Just as thereís more than one way to skin a cat, this atmospheric CO2 enrichment study demonstrates thereís more than one way for a plant to increase its water use efficiency and biomass production.

Effects of Elevated CO2 on Decomposition of Ash Tree Litter: How will the ongoing rise in the airís CO2 content affect the decomposition of leaf litter and, hence, the carbon sequestering prowess of ash trees?  Evidence continues to mount that it will ...
