Editorial
A New Perspective on the Warming of the North Pacific Ocean Over the Last Half of the 20th Century: How much did eastern North Pacific sea surface temperatures rise over this period?  How smooth was the temperature rise?  What did not cause it?  What did?

Subject Index Summaries
Aerosols (Biological - Terrestrial): Multiple intriguing interactions among rising atmospheric CO2 concentrations, increasing air temperatures, and aerosols produced by terrestrial plants bode well for the continued robustness of the biosphere.

Trees (Early Spring Growth): Mounting evidence suggests that the aerial fertilization effect of atmospheric CO2 enrichment is several times stronger than normal in woody plants when they first begin to produce new foliage in the spring, and that this phenomenon has played a significant role in the progressively earlier occurrence of biological spring over the past few decades.

Journal Reviews
Modeling Permafrost: Which provides a more accurate representation of permafrost trends, a two- or three-layer model?  And which is typically employed by climate alarmists?

800 Years of Siberian Climate: Are the Medieval Warm Period and Little Ice Age evident in the new record?

Interpreting Sea Level Trends: Documenting change in sea level is problem enough.  Determining what caused the change complicates things even more.

CO2 Effects on Wheat Quantity and Quality: Although most people acknowledge that wheat yields will likely increase in a future CO2-enriched world, there have been periodic predictions that its quality will be reduced.  A new field study sheds some important light on this subject.

Combined Effects of CO2 and O3 on Nonstructural Carbohydrates of Beech and Spruce: Are the negative effects of O3 too much for the positive effects of CO2 to overcome?
