Current Editorial
The Medieval Warm Period and Little Ice Age: Their Untimely Demise and Welcome Resurrection: A new paper in Science - the significance of which can hardly be overstated - has breathed renewed life into two important periods of earth's climatic history that were consigned to oblivion just a few short years ago by the infamous "hockey stick" temperature history of Mann et al., which temporarily provided crucial empirical support for the political movement dedicated to mandating worldwide reductions in anthropogenic CO2 emissions when climate model predictions did not appear to be capable of carrying the day on their own.

Subject Index Summaries
Antarctica (Biology): Life's toe-hold on Antarctica could well be increased to a foot-hold if the world becomes warmer and wetter, as is generally predicted for the future by today's state-of-the-art climate models (but for the wrong reason) and as is suggested by the current state of the millennial-scale oscillation that has ruled earth's climate through glacial and interglacial period alike.

Trees (Type - Beech): A summary of some of the recently published literature suggests that increases in the air's CO2 content will enhance photosynthetic rates and biomass production in beech trees, which are economically important forest species in many places around the globe.

Carbon Sequestration Commentary
Will Forest Carbon Sink Capacity Fade Away as Trees Age?: Climate alarmists would have us believe that forests will only function as significant carbon sinks while they are young and vigorous.  Real-world data, however, suggest this model-based "age discrimination" is without much merit.  In fact, the measurements show it's flat out wrong.

Current Journal Reviews
Sea Level Trends at Kolobrzeg, Poland: Annual mean sea level increased steadily over the past century, with no signs of any acceleration.  Annual maximum sea level, however, did not increase, indicative of a possible decrease in storm surge intensity over the past century.

Primary Productivity Dynamics in the Sulu Sea: Counts of coccolithophores in a deep-sea sediment core speak volumes about earth's past climate, help us understand current climate change, and enlighten us about what we can expect in the way of future climate.

Effects of Elevated CO2 and Ozone Concentrations on Spring Wheat Grown at Different Levels of Soil Nitrogen Supply: What happens when all three of these environmental parameters - atmospheric CO2 and ozone concentration and soil nitrogen content - are increased at the same time, as often happens in both agricultural and natural settings?  Since elevated tropospheric ozone concentrations cause billions of dollars of damages in marketable crop losses each year, this is much more than an academic question.

Atmospheric CO2 and Sap-Feeding Herbivores: As the air's CO2 content rises, will sap-feeding insect herbivores - like aphids and leafhoppers - change their feeding habits and growth patterns?
