Editorial
Global Warming and Mortality: People in all parts of the world die at increased rates during times of greatest relative heat and cold in their specific locations.  Which is the most dangerous of these extremes?

Subject Index Summaries
Volcanic Eruptions (Biological Impact): Several recent studies suggest that volcanic eruptions may significantly enhance the photosynthetic activity of the biosphere.

UV-B Radiation (Effects on Marine Ecosystems): How does UV-B radiation affect marine plant life, and how is this relationship affected by atmospheric CO2 enrichment?

Journal Reviews
Thickness Trends of the Antarctic Ice Sheet: How did different portions of it vary over the last five years of the 20th century?

Assessing the Sensitivity and Accuracy of State-of-the Art Climate Models: A new study describes what its authors say is "the best chance we have for a well-characterized, rigorous test."

The Roman Warm Period and Dark Ages Cold Period in China: New data confirm their existence and add to the voluminous evidence for the natural millennial-scale oscillation of global climate that has established the Modern Warm Period independently of the coincidental concomitant rise in the air's CO2 content.

Effects of Elevated CO2 on Aboveground Net Primary Production of Poplar Trees After Canopy Closure: It had long been thought by many that once canopy closure occurred, atmospheric CO2 enrichment would no longer enhance the growth of forests.  Now, however ...
