A 1200-Year History of Total Solar Irradiance: What can it tell us about the nature of the Modern Warm Period in which we currently live?

Subject Index Summaries
Medieval Warm Period (Europe): Climate alarmists have gone to great lengths over the past few years to try to convince the world that the earth is currently a much warmer place than it was at any other time during the past millennium.  The Medieval Warm Period is thus a major embarrassment to them; and they have consequently decreed that it never occurred over most of the planet, and that where it did occur, it was really not all that warm.  A growing body of real-world data, however, suggests otherwise; and in this summary we report on some of the recent pertinent results that have come out of Europe.

Transpiration: How would earth's plants likely deal with water shortages in a CO2-enriched world of the future that might also be a bit warmer than it is now?

Journal Reviews
The Incredible Regularity of Periodic Abrupt Climate Change: The author analyzes what he calls the "mystery 1,500-year cycle" of glacial-period Dansgaard-Oeschger warming events, which mystery, in his words, is "one of the key issues in climatology that needs to be explained."  His findings go a long way towards doing so; and their implications reach all the way to the ongoing debate about the climatic effects of the ongoing rise in the air's CO2 content.

Does Global Warming Enhance the Planet's Monsoon Circulations?: Climate models say it should.  Real-world data, however, suggest otherwise.

Snow Water Equivalent of the Western Colorado Snowpack: How has it varied over the past several centuries?

Growth and Root Chemistry Responses of Paper Birch and Sugar Maple to Atmospheric CO2 Enrichment: What are they?  And what are their ramifications?

The Photosynthetic Response of Muskmelon to Increases in the Air's Temperature and CO2 Concentration: Studies conducted in China suggest positive responses to both of these environmental changes.
