Current Editorial
The 13 May 2003 Testimony of Dr. John Christy Before the U.S. House of Representatives' Committee on Resources: In the wake of the recent publication in Science of a paper that purports to provide evidence for the reality of human-induced global warming, one of the scientists who oversees the processing of the satellite data that play a crucial role in this discussion presented his ideas on the subject to the American public via written congressional testimony, which we reprint here for all to see.

Subject Index Summaries
Glacial-Interglacial Climate Cycles: Their study can provide us much food for thought about current climate concerns.

Long-Term Studies (Woody Plants - Pine Trees): How will pine trees respond to the ongoing rise in the air's CO2 content that began with the Industrial Revolution?  Will our enriching of the air with carbon dioxide enable them to grow bigger and better or will it weaken them?

Current Journal Reviews
Millennial-Scale Climate Oscillations of the Last Glacial Cycle: Are they restricted to lands bordering the North Atlantic Ocean?  What is their periodicity?  How are they caused?  Do they have anything to do with 20th century warming?  A single paper answers many questions.

North Atlantic Deep Water (NADW) Formation During the Holocene: On what time scales has NADW formation varied?  How does its variability compare with that of earth's climate?  What do the results suggest about the ultimate cause of NADW and climate variability?

Wet-Dry Cycles of the Central and Southern Rocky Mountains, USA: Is there anything threatening, or extremely unusual, or even mildly unusual, about the way in which wet and dry periods have come and gone over the past century of what climate alarmists like to call "unprecedented global warming," which is supposed to lead (according to them) to all sorts of extremely bad things?

Effects of Elevated CO2 on the Abundance of Protozoa in Soil: Why would anyone even be concerned about the subject?

Not Every Plant Is a Winner at Responding to Elevated CO2: It may perhaps appear to some that we report only positive responses of plants to atmospheric CO2 enrichment.  If so, it is only because most plant responses are positive.  Once in a while, however, there is a non-positive-responder; and this is one of those times.
