Current Editorial
Humanity’s Impacts on Clouds: Could They Lead to Global Cooling?: Human-induced global cooling?  Have we gone stark-raving mad?  Read on and see.  Our heads may be in the clouds, but it’s only to learn what’s going on up there.

Subject Index Summaries
North American Temperature Trends: Is North America really experiencing a dramatic warming trend, as climate alarmists claim?  How do current temperatures on the continent, or slightly off-shore, compare with those of times past?  These and other pertinent questions have been repeatedly assessed by scientific studies that tell a much different story than what the public has been led to believe in recent years.

Plant Growth Response to CO2 and Nitrogen (Fungi): Symbiotic fungi often provide plants with increased water and soil nutrients in return for photosynthetically-derived carbon products.  As the CO2 content of the air rises, these relationships could be altered by additional influences provided by soil nitrogen concentration, as briefly described in this summary of pertinent research.

Current Journal Reviews
The Odden Ice Tongue of the Greenland Sea: The tongues of humans tell tales, some of them quite tall.  This tongue of ice, however, tells the cold hard truth.

A Three-Thousand Year Record of South African Temperatures: Do the Medieval Warm Period and Little Ice Age – which climate alarmists claim to be only a North Atlantic phenomenon – appear in the record?  Yes.  Does the climate alarmists’ "unprecedented" warming of the last two decades appear?  No.

The Little Ice Age Climate in the Caribbean Sea: Not only did the Little Ice Age bring cold temperatures to the Caribbean Sea, it also brought an increase in precipitation variability, which is just the opposite of what climate alarmists suggest should happen in response to rising temperatures.  Could they possibly be wrong?

Elevated CO2 Completely Ameliorates SO2 Damage in Soybean: As an aerial pollutant, SO2 is responsible for causing severe reductions in the growth and yields of many crops; while as an aerial fertilizer, CO2 is responsible for causing significant increases in these parameters.  In this study, the authors investigated how soybeans respond to simultaneous increases in the atmospheric concentrations of both of these gases.

Differential Responses of Peat Moss to Elevated CO2 and Nitrogen Supply: Vascular plants show differing responses to atmospheric CO2 enrichment, ranging from highly positive to next to nothing.  It is logical, therefore, to expect nonvascular plants to also display a wide range of responses to increases in the air’s CO2 content.  This study illustrates that phenomenon with respect to two species of Sphagnum moss.
