Current Editorial
Global Climate Change: According to Hoyle... and Wickramasinghe Too!: Two of the most brilliant minds of our time have put their heads together to derive a fresh new view of earth's climate history.  What it has to say about the ongoing rise in the air's CO2 content is stunning.

Subject Index Summaries
Climate Model Inadequacies (Radiation): When it comes to accurately simulating the many intricacies of earth's radiative energy balance, state-of-the-art climate models are just not up to the task.

Trees (Long-Term Studies): As the air's CO2 content continues to rise, earth's trees and shrubs will likely display significantly enhanced rates of photosynthesis and biomass production, removing enormous amounts of carbon from the atmosphere and sequestering it in their tissues for decades, centuries and even millennia.

Current Journal Reviews
Variations in Atmospheric CO2, Temperature and Global Ice Volume Derived from the Vostok Ice Core: Once again, it is demonstrated that changes in atmospheric CO2 concentration followed changes in air temperature by thousands of years over the past four glacial/interglacial cycles, and that global ice volume lagged even further behind, suggesting that the current rate of rise of sea level may be more related to the warm conditions of the mid-Holocene (4 to 7 thousand years ago) than to more recent 20th Century warming.

Solar Radius Variations and Climate Change on Earth: Changes in earth's temperature are shown to be correlated with changes in the sun's radius, proving nothing, but raising many questions that need resolving before we blame something else for terrestrial climate changes that may trace their origins to phenomena originating on the sun.

Effects of Increased Air Temperature and CO2 Concentration on the Yield of French Beans: It had to happen sometime: atmospheric CO2 enrichment failed to stimulate yield in French beans in an experiment designed to study the effects of predicted global change on UK agriculture.  But when air temperature was raised...

Long-Term Effects of Elevated Atmospheric CO2 on Soil Fungi: A revealing new study of beneficial soil fungi associated with the roots of plants exposed to elevated concentrations of atmospheric CO2 for approximately twenty years has recorded astounding positive responses that portend incredible benefits for earth's ecosystems.

Effects of Elevated CO2 on a Scrub Oak Species: Though small of stature, the scrub oak of Florida is big on CO2.  In a recent three-year-long study, a doubling of the air's CO2 concentration enhanced the tree's water use efficiency by two- to three-fold!
