Editorial
The Major Impacts of Global Warming and Atmospheric CO2 Enrichment on Vegetation: What are they? ... and are they generally beneficial or detrimental to earth's plants?

Subject Index Summaries
Precipitation (Trends - Regional: North America, United States) : Has the post-Little Ice Age warming of the world led to more worrisome variability and/or extremes of precipitation, as climate alarmists would have us believe?

Nutrients x CO2 Effects on Plants (General): Does low soil fertility negate the ability of atmospheric CO2 enrichment to enhance the growth of plants, as climate-alarmists would like us to believe?

Journal Reviews
The Overdue-Glaciation Hypothesis: Is it possible that anthropogenic CO2 and CH4 emissions may have already staved off an ice age that would otherwise be bearing down upon us? ... and that we must continue emitting CO2 to the atmosphere to keep the incipient ice age at bay?

A Paleo-Perspective on Western U.S. Droughts: How do the worst droughts of the 20th century - the latter two decades of which are claimed by climate alarmists to have been the warmest period of the past two millennia - compare with extreme droughts of prior centuries, when there was much less CO2 in the air and they claim it was also much colder?

A 6700-Year Temperature History of Northern Quebec-Labrador, Canada: How well does it harmonize in its latter stages with the hockeystick temperature history of Mann et al.? ... and how well does it support the climate-alarmist contention that temperature becomes more variable when the climate warms?

Decomposition of Leaf Litter of Paper Birch Trees in Ambient and CO2- and O3-Enriched Air: As the atmospheric concentrations of carbon dioxide and ozone continue to rise, what is their impact on the leaf litter decomposition rates of paper birch trees and the ultimate ability of such forest stands to sequester carbon in the soils upon which they grow?

The Effect of Very High Atmospheric CO2 Concentrations on the Growth of Unicellular Green Algae: Are algae as responsive to atmospheric CO2 enrichment as higher plants are?  And just how much CO2 can they tolerate?
