Editorial
The Medieval Warm Period in the Central Alps of Austria: How does it compare with what is suggested by other Northern Hemispheric temperature reconstructions?  And what does the new study imply about the relative roles of solar and atmospheric CO2 forcing of climate over the past two millennia?

Subject Index Summaries
"Little" Medieval Warm Period: In addition to the voluminous evidence that continues to accumulate for the occurrence of higher-than-present temperatures during the Roman Warm Period of 2000 years ago and the Medieval Warm Period of 1000 years ago, a growing body of evidence is beginning to indicate there was a period of time some 500 years ago when temperatures were also warmer than they are currently.

Long-Term Studies (Non-Woody Plants): Will the positive effects of atmospheric CO2 enrichment observed in short-term studies of non-woody plants gradually dwindle away as the air's CO2 content continues to rise?  Climate alarmists would have you believe they will.  Long-term experiments suggest otherwise.

Journal Reviews
20th-Century ENSO Events: Are they becoming more frequent and more severe?

A Climate History of the Northwestern Mediterranean Region: How have the temperatures of this region fluctuated over the course of the Holocene, and what do they reveal about the Modern Warm Period?

Primary Production in the Adriatic Sea: How has it varied over the past four decades?

Growth Responses of Five-Species Ecosystems to Atmospheric CO2 Enrichment: What do they suggest about potential changes in the species richness of earth's ecosystems as the air's CO2 content continues to rise?

Effects of Elevated CO2 on the Reproduction and Progeny of a Dioecious Plant: Is it a help or a hindrance?
