Editorial
A New Twist on the Old Threat of an Imminent Release of Vast Amounts of CO2 from the World's Peatlands: "Global warming is set to dramatically worsen because of huge amounts of carbon dioxide being released from the world's peatlands, a study has found." - Steve Connor, Science Editor of The Independent (Independent.co.uk), 8 July 2004.  Do you believe it?

Subject Index Summaries
Methane (Atmospheric Concentrations): The historical upward trend in the atmosphere's methane concentration (and, hence, its potential to further warm the globe) has slowed dramatically over the past two decades, possibly even halting altogether, due in some significant degree to changes in a suite of complex phenomena driven by the concomitant rise in the air's CO2 content.

Isoprene: What is it?  How is it influenced by the air's CO2 content?  And why do we care?

Journal Reviews
Ice Core Temperature Reconstructions from Svalbard, Norway: How strongly do they support the climate-alarmist claim that what they call the unprecedented warming of the 20th century was caused by the concomitant increase in the atmosphere's CO2 concentration?

Outlet Glaciers of the Myrdalsjokull Ice Cap of Iceland: What can their behavior tell us about the nature of 20th century warming?

The Effects of Elevated CO2 on Medicinal Substances Found in St. John's Wort Plants: In terms of both total plant biomass and tissue concentrations, they are, to say the least, very substantial.

CO2 and Temperature Effects on Wood Density of Scots Pines: As the air's CO2 content and temperature continue to rise, what will happen to the strength of the wood produced by trees growing under these supposedly adverse conditions?

Photosynthesis in Second-Generation Pine Trees Grown in Air of Elevated CO2 Concentration: Will the capacity for enhanced photosynthesis in trees growing in CO2-enriched air be lost in subsequent generations, as trees acclimate to higher concentrations of carbon dioxide?
