Editorial
CO2-Induced Soil Microfauna Changes in a New Zealand Pasture: The changes are many and varied, but they all appear to bode well for the biosphere.

Subject Index Summaries
Hail: How has the frequency of hailstorm occurrence varied over the past century or so?  Has it increased with the progression of 20th century global warming, as climate alarmists would have us believe?

Nutrients x CO2 Effects on Plants (Nitrogen - Agricultural Crops: Rice): How does the degree of soil nitrogen availability impact the aerial fertilization effect of atmospheric CO2 enrichment on rice production?

Journal Reviews
A Century of Change in Arctic Sea Ice: What do the data tell us about the qualitative and quantitative aspects of climate model predictions of CO2-induced global warming?

Cyclical Environmental Change Depicted in Lake Sediments of Northern Russia: Does the millennial-scale oscillation bear evidence of the Modern Warm Period, Little Ice Age, Medieval Warm Period, Dark Ages Cold Period and Roman Warm Period?  Of course it does.

Effects of Elevated Air Temperature and CO2 Concentration on Nordic Trees: Based on everything we know about tree responses to elevated CO2 and temperature, the trees of Denmark, Finland, Iceland, Norway and Sweden are going to love the Modern Warm Period.

Does Elevated Atmospheric CO2 Protect Soybeans Against Ozone Damage?: This question is asked and answered by three scientists from the Departments of Plant Biology and Crop Sciences at the University of Illinois in Urbana, Illinois, USA.

Did a Pacific Ocean Regime Shift Occur at the Turn of the Last Century?: Do aquatic conditions along the western coast of North America gradually change over time, or do they periodically "shift gears" and jump to a new state of quasi-equilibrium in as short a time span as a year?
