Current Editorial
CO2 and Biodiversity: Does the Former Affect the Latter?: Extinction is a chilling word, for it denominates the utter annihilation of a unique plant or animal; and with the loss of but a single species, earth's biosphere is the less and the entire planet is impoverished.  What is the relationship of this subject to the ongoing rise in the air's CO2 content?  Will it exacerbate the sorry situation that currently confronts us?  Or will it ameliorate it?

Subject Index Summaries
C4 Plants (Water Use Efficiency): A brief review of the scientific literature indicates that future increases in the air's CO2 concentration will likely enhance the water-use efficiency of most C4 plants.

Wind: In the virtual "model world" of climate alarmists, all sorts of weather extremes, including winds, get ever stronger as the air's CO2 content continues to climb.  In the real world of nature, however, things behave a little differently.

Current Journal Reviews
Growing Season Trends in Northern Taiga Forests of Russia: Do they dance to the beat of the climate-alarmist drummers?

Testing The Current Generation of Climate Models: Do any of you really believe they past muster?

Elevated CO2 Increases Sucrose-Phosphate Synthase Activity in Rice: Some plants exhibit photosynthetic acclimation (decreases in photosynthesis) in response to long-term atmospheric CO2 enrichment.  In the experiment described in this paper, however, rice plants fail to do so, possibly by synthesizing and exporting sucrose from mature source leaves into actively growing sink tissues.  The authors explain how this process may be mediated by specific enzymes they studied.

Acclimation of Arabidopsis thaliana to Elevated CO2: The authors of the paper describing this study used Arabidopsis thaliana to elucidate the mechanisms responsible for causing photosynthetic acclimation in response to atmospheric CO2 enrichment in certain plants.

Varied Responses of Plantago lanceolata to Elevated CO2: The authors studied 18 different families of Plantago lanceolata to determine if elevated CO2 impacted genetically different plants to different degrees.
