Current Editorial
Water Transparency: The Neglected Factor in Coral Decline: As more and more CO2 makes its way into the atmosphere, climate alarmists claim it is killing coral reefs by causing global warming that induces coral bleaching.  Perhaps they should be looking down at the water in which the corals grow ... and seeing how clear it looks.

Subject Index Summaries
Glaciers (Global): Are earth's glaciers melting away at an accelerating pace, as climate alarmists claim they are, in what they claim is a rapidly warming world, which they claim to be due to the ongoing rise in the air's CO2 content?

Rubisco (Tree Species): A review of some of the pertinent recent literature demonstrates that increases in the air's CO2 content often cause reductions in the amount and/or activity of the photosynthetic enzyme rubisco within woody plants, but that this phenomenon does not completely negate CO2-induced increases in photosynthetic rates and is, in fact, beneficial to overall plant growth.

Current Journal Reviews
Glaciers and Sea Levels: What do we know about this dynamic duo?  Not as much as we need to know to be able to accurately predict their future interactions.

Diffuse-Light-Enhanced Photosynthesis Revisited: A massive study conducted by 33 scientists in 11 different countries corroborates one of the key elements of a negative feedback phenomenon -- described in our Editorial of 10 October 2001 -- that tends to counteract the greenhouse effect of anthropogenic CO2 emissions.

Different Patterns of Climate Change in Eurasia and North America Prove Plants Like Higher Temperatures in a CO2-Accumulating Atmosphere: Would you believe that CO2-induced global warming would actually be good for the biosphere?  Real-world growth of Northern Hemispheric vegetation over the past two decades make the case for this conclusion.

Effect of Elevated CO2 on Photosynthesis and Growth in a Sunfleck Light Regime: Previous research has demonstrated that elevated CO2 can stimulate photosynthetic rates at low levels of irradiance in a number of species.  In this paper, researchers investigate whether or not elevated CO2 stimulates photosynthesis and growth in an understory tropical rain forest seedling in an intermittent irradiance regime typical of sunflecks.

The Carbon Balance of the Seas: A major new review assesses what we know and do not know about the production and decomposition of organic matter in the world's oceans.
