Biased Towards Extinction: David R.B. Stockwell of the University of California's San Diego Supercomputer Center describes some serious shortcomings of a study published earlier this year in Nature, which suggests that CO2-induced global warming is rapidly pushing much of earth's plant and animal life towards the brink of extinction.

Subject Index Summaries
Roman Warm Period (Europe): How does the warmth of today's Europe compare with the warmth of the Europe of two thousand years ago, when the atmosphere's CO2 concentration was 100 ppm less than it is currently?

Nutrients x CO2 Effects on Plants (Nitrogen - Trees: Pine): How does the degree of soil nitrogen availability impact the aerial fertilization effect of atmospheric CO2 enrichment on the growth of pine trees?

Journal Reviews
Large-Scale Treeline Advances in the Circumpolar Northern Hemisphere: They appear to be a response to 20th-century global warming, particularly that of the last half-century; but they reveal that the Modern Warm Period has yet to achieve the level of warmth characteristic of the Medieval Warm Period.

Riverine Transport of Dissolved Organic Carbon to the Arctic Ocean: What does it tell us about the climate-alarmist claim that the Arctic, acting as a climate-change canary in a planetary coal mine, will be the first and foremost place on earth to experience unprecedented CO2-induced global warming, which, as they also claim, is already occurring?

The Medieval Warm Period and Little Ice Age in New Zealand: Did they really exist?  And were they as extreme as what occurred contemporaneously in regions bordering the North Atlantic Ocean?

Arbuscular Mycorrhizal Fungi: Their Responses to Long-Term Atmospheric CO2 Enrichment: Are fungal symbionts benefited by higher levels of atmospheric CO2?  And if they are, what are the consequences for the plants that host them on their roots?

Response of a Tropical Legume Tree to Elevated CO2: A group of scientists from Brazil investigate the effects of atmospheric CO2 enrichment on one of the most important trees of the tropical forests of the Americans.
