Current Editorial
Most of North America Fails to Board 20th-Century Climate Catastrophe Train: Climate alarmists claim global warming will lead to large increases in deadly hot weather events.  They also claim the last hundred years saw the earth warm at a rate that was unprecedented over the past millennium.  Hence, there should have been a huge increase in debilitating heat waves over the past century.  Right?

Subject Index Summaries
ENSO (Model Inadequacies): State-of-the-art climate model simulations of ENSO present a distorted view of reality, which suggests they could well be missing the mark in other important areas as well.

Rubisco (Grassland Species): A review of some of the recent literature demonstrates that increases in the air's CO2 content often cause reductions in the amount and/or activity of the photosynthetic enzyme rubisco found in grassland plants without completely negating CO2-induced increases in their rates of photosynthesis.

Current Journal Reviews
Coastal Southern Greenland Temperature History: 1958-2001: What does it tell us about the potential melting of the Greenland Ice Sheet in a slightly warming world?

Reconstructions of Spring Precipitation in Southwestern Turkey from 1339 to 1998: What can they tell us about climate-alarmist claims that CO2-induced global warming will lead to more frequent and more extreme droughts and floods?

Effects of Elevated CO2 and O3 on Plant-Insect Interactions in a Trembling Aspen Forest: This unique study clearly demonstrates the great importance of the ongoing rise in the air's CO2 content to the future well-being of one of the world's most widespread tree species.

Effects of Elevated CO2 and Soil Moisture on a Chinese Variety of Spring Wheat: Plants sometimes exhibit different responses to atmospheric CO2 enrichment under different soil moisture conditions.  How will a Chinese spring wheat cultivar respond to elevated CO2 when water is limiting to its growth?

Effects of Elevated Air Temperature and CO2 Concentration on Stem-Diameter Growth in Mature Scots Pine Trees: With adequate fertilization, trees exposed to elevated CO2 generally exhibit increased growth rates at current air temperatures.  But what happens to trees growing on soils low in nitrogen?  And what happens if it suddenly warms by 4C at the start of CO2 enrichment?
