Temperature Record of the Week
This issue's Temperature Record of the week is from McGill, Nevada. Visit our U.S. Climate Data section to plot and view these data for yourself.

Low-Frequency Signals in Long Tree-Ring Chronologies Reveal the Existence of Multi-Centennial-Scale Temperature Trends of the Past Millennium*: What do the newest findings suggest about the hockeystick temperature history of Mann et al., which serves as the centerpiece of the political movement that seeks to subvert the world community of nations' carbon-based economy?

*This editorial is dedicated to the memory of John Daly, who fought long and hard to demonstrate the non-uniqueness of late 20th century temperatures.  He will yet be recognized by all as having been correct on this important point.

Subject Index Summaries
Climate Oscillations (Millennial Variability: Europe): From continent to continent, the story of earth's late-Holocene climatic history continues to repeat itself, oscillating from Little Ice Age to Modern Warm Period conditions on a solar-pegged schedule that repeats itself with considerable fidelity.

Agriculture (Species: Potato): A summary of some of the recently published literature suggests that the ongoing rise in the air's CO2 content will significantly enhance the production of potatoes wherever they are grown throughout the world.

Journal Reviews
Questions About Purported Late 20th Century Warmth Raised by Tree-Ring Data: More bad news for Mann et al., as analyses of maximum latewood density chronologies from trees sampled at close to 400 Northern Hemispheric locations fail to support their principal contentions, as well as those of the IPCC.

A 500-Year Temperature History of a Site on the North Coast of Sicily: Another study casts multiple doubts on the hockeystick temperature history of Mann et al. while providing support for the analysis of McIntyre and McKitrick.

A History and Projection of Global Sea Level: All we have to fear about the future, it would appear, is fear itself.

Effects of Atmospheric CO2 Enrichment on the Physiological and Biochemical Responses of Maize to Chilling Temperatures: Just as enriching the air with CO2 typically helps plants to tolerate warmer temperatures, it often helps them tolerate colder temperatures as well.

CO2-Induced Increases in Grassland Productivity: Do They Disappear Over Time?: Some would have you believe they do but they are wrong.
