Current Editorial
The Future of Earth's Vegetation: What Will the Landscape Look Like in a High-CO2 World?  A Case Study of the Mediterranean Region: What if the earth experiences a CO2-induced warming somewhere in the middle of the ever-widening range of what is currently predicted for the future?  What will happen?  Specifically, what will happen in areas where moisture is at a premium and warming might be expected to exacerbate the situation?  A recent study of lands surrounding the Mediterranean Sea gives us a glimpse of what we could logically expect to occur.

Subject Index Summaries
Hurricanes (Atlantic Ocean - Global Warming Effects): Will hurricanes become more frequent and intense if the planet warms?  Climate alarmists routinely say they will.  Real-world data, on the other hand, tell a vastly different story ... which is the one reported here.

Trees (Type - Nitrogen-Fixing): Nearly all woody species respond to increases in the air's CO2 content by displaying enhanced rates of photosynthesis and biomass production.  But will nitrogen-fixing trees exhibit such responses, due to the large energy demands of their symbiotic relationships with nitrogen-fixing bacteria?  In this summary we seek answers to this question, as we review several recently published responses of nitrogen-fixing trees to atmospheric CO2 enrichment

Carbon Sequestration Commentary
Are Natural Lakes and Man-Made Reservoirs Significant Sinks for Anthropogenic Carbon?: Read on.  The answer may surprise you.

Current Journal Reviews
Climate Change At the Source of the Holy Ganga: The site is a long ways from the North Atlantic Ocean, but the climatic histories of the two locations proceed in lockstep fashion over the past 2000 years, revealing the global nature of the millennial-scale climatic oscillation that rules the world and is ushering in the planet's Modern Warm Period.

Earlier Springs: A Consequence of Global Warming or North Atlantic Oscillation?: Inquiring minds want to know.

Florida Wildfires and ENSO: Is There a Relationship?: Yes, there is.  And you've got to love it!

The Impact of Elevated CO2 On Carbon Uptake in Sunflower: Sunflower seeds.  One of mankind's favorite snack foods.  You eat one, and you can't put the bag down until its empty.  How will the plants that produce them respond to increases in the air's CO2 content?  Better find out quick!

Growth Responses of Young Beech and Spruce Trees to Atmospheric CO2 Enrichment When Rooted in Acidic and Calcareous Soils: Will beech and spruce trees respond differently to the ongoing rise in the air's CO2 content when growing on different types of soil?  This paper presents the initial results of a long-term study designed to answer this question.
