Increasing Export of Alkalinity by the Mississippi River: Evidence of Ever-Increasing Terrestrial Productivity: Alkalinity.  Invisible to the eye, the bicarbonate ions of which it is comprised flow down the world's rivers, carrying carbon to the sea that is ultimately sequestered in ocean sediments.  But what creates it, and what enhances its creation, is almost as important as what it does.

Subject Index Summaries
Aerosols (Biological - Aquatic): Aerosol-producing biological processes that occur in the upper layers of the world's oceans stimulate a number of interrelated physical phenomena that act to resist extreme changes in global air temperature and thus maintain earth's physical environment in a state conducive to the continued existence of life.

Roots (Crops): What we don't normally see in CO2-enrichment experiments (roots) may well be more important than what we do see (aboveground growth).

Journal Reviews
A Century of Climate on the True Prairie of the Central United States: How much different was it from the climate of the several millennia that proceeded it?

Recent Runoff Trends of Major World Rivers: Whether rivers rush or meander sluggishly to the sea, the story they tell about purported global warming and its purported impacts is significantly at odds with the (tall) tale told by climate alarmists.

The Resiliency of the Coral Communities on the Outer Slope of Moorea, French Polynesia: Does periodic bleaching eliminate zooxanthellae that are unable to cope with high temperatures and replace them with ones that are more fit for warmer conditions?

Effects of Increases in the Air's CO2 Content and Temperature on Condensed Tannins in Birch Leaves: What are they?  And what do they have to do with global warming?
