Editorial
Plant Micronutrient Concentrations in a CO2-Enriched World: In a series of Editorials published in CO2 Science Magazine (30 Oct 2002, 20 Nov 2002, 27 Nov 2002a and 27 Nov 2002b), we and one of our Scientific Advisors debate the effects of atmospheric CO2 enrichment on plant micro-nutrient levels and, ultimately, human health and longevity.  Now, a FACE study that broaches the subject much more directly has been published.  Which way does it tend to tip the scales?

Subject Index Summaries
Antarctica (Ice Shelves): Is there anything about ice shelf behavior along the coasts of Antarctica that can be considered evidence of unprecedented, or even modest, CO2-induced global warming?

Worms: They are some of the lowliest life forms on the planet - "out of sight, out of mind," to most of us - but they figure prominently in the CO2-induced rejuvenation of the biosphere that is currently taking place and right beneath our feet.

Journal Reviews
Hurricane Intensity vs. Temperature: How has the former responded to what climate alarmists typically describe as the unprecedented increase of the latter over the past quarter-century?

U.S. Tropical Cyclone Landfalls: 1950-2002: How were their numbers influenced by ENSO activity over this period?

Effects of Drought on Trace Gas Emissions from the Soil of an Amazon Forest: Any CO2-induced warming that might induce regional drying over the Amazon Basin would likely induce a strong negative feedback that would significantly temper, or maybe even totally eliminate, the impetus for warming.

Effects of Atmospheric CO2 Enrichment on Plant Respiration: Are they real?

Added Upon: Indirect Effects of Atmospheric CO2 Enrichment on the Productivity of Grasslands and Deserts: Experiments designed to reveal the primary photosynthetic or biomass responses of plants to increases in the air's CO2 content under controlled environmental conditions may not reveal their full potential for response in natural settings.
