Twentieth-Century Warming of the Northern Hemisphere: Has it really been as phenomenal as climate-alarmists claim it has?  The answer to this question rests upon a single critical assumption.

Subject Index Summaries
Climate Oscillations (Millennial Variability - Africa): Was the warming that rescued the world from the debilitating cold of the Little Ice Age driven by anthropogenic CO2 emissions, or was it merely the next "scheduled" phase of a millennial-scale oscillation of climate that has existed from time immemorial?  In this Summary, we review evidence relevant to this question that comes from the continent of Africa.

Long-Term Studies (Woody Plants: Spruce): How do spruce trees respond to long-term atmospheric CO2 enrichment?

Journal Reviews
A New Ice Core from North Greenland: Some of the most basic features of the proxy climate record of the new ice core reaffirm some of the most basic aspects of real-world climate change, which are (not unexpectedly) rather different from what the world's climate alarmists continually preach.

Errors in Solar Activity and Terrestrial Climate Data: We suggest an alternative view of a new twist on an old subject.

A 7500-Year Proxy Climate Record for Finnish Lapland: How does the 20th century compare with all prior centuries of the record in terms of (1) absolute level of midsummer warmth, i.e., mean midsummer temperature, and (2) the rate at which midsummer temperature rose in attaining that level?

Chinese Agricultural Productivity in a Warmer, Wetter World: Will what climate models predict for China in the way of future weather be a help or a hindrance to the country's ability to feed itself?

Nitrogen Cycling in a CO2-Enriched Sweetgum Plantation: As the air's CO2 content continues to climb, some scientists have supposed that many forests may not be able to respond positively in terms of increased productivity with the limited supplies of nitrogen currently believed to reside in their soils.  However, an impressive FACE experiment that has been churning out data for over six years suggests this supposition may be false.
