1. GLOBAL WARMING: ANOTHER DISPUTE SEEMS TO HAVE BEEN RESOLVED.

Homo sapiens has been around for maybe 50,000 years, but most of what we've learned about our universe, from how big it is to how small its pieces are, has been learned in the span of a single human lifetime. What made it possible was the development of a scientific culture that is open and conditional. The effect of homo sapiens on Earth's climate is perhaps the most complicated problem humans have tackled, and conceivably the most important. The system is working. We have a consensus on warming; disputes remain only over the details. One detail was records that were interpreted by a group at the U. Alabama in Huntsville as showing that the troposphere had not warmed in two decades and the tropics had cooled. However, three papers in Science this week report errors in the Alabama-Huntsville calculations. It seems that warming of the troposphere agrees with surface measurements and recent computer predictions. The group at Alabama-Huntsville concedes the error, but says the effect is not that large. That's the way it's supposed to work. It's a textbook example of science in the process of resolving a very complicated problem.

2. CREATIONISM: ABC NEWS AND GETTING THE DINOSAURS ON NOAH'S ARK.

Earlier this year, WN asked a rhetorical question, "Is ABC News nuts?" (WN 11 Feb 05). There is new information. Last night, ABC Evening News took viewers to the Museum of Earth History in Eureka Springs, Ark. Disputes are different in the Bible world. Genesis says a pair of every kind of air-breathing animal was taken on board Noah's Ark and in a world that's only 10,000 years old, that must include dinosaurs. Or it may be that the reporter, Jake Tapper, went to school in Kansas. "Religious views of creat ion that challenge accepted science are gaining support across the country," he told viewers, "The Kansas Board of Education this week tentatively endorsed new standards allowing more criticism of evolution in explaining the origins of life." As further proof, ABC showed President Bush delivering his "intelligent design should be taught in schools" remarks. To balance the President, science had AAAS CEO Alan Leshner, "I have no problem with people talking about religion as religion or belief as belief." Hmmm. "It's dangerous to talk about religious belief as if it were science." So what was ABC's conclusion? "Science is increasingly on the defensive."

3. SPACE: A FLAWLESS LAUNCH OF THE MARS RECONNAISSANCE ORBITER.

The journey will take seven months, and it will remain in Mars orbit four years, sending back information on weather, climate and geology. It's not likely to find a reason to send humans.

4. PHILIP KLASS: TIRELESS DEBUNKER OF UFO FANTASIES DIES AT 85.

An electrical engineer and senior editor of Aviation Week, Klass offered a $10,000 prize for solid scientific evidence of visits by extraterrestrials. He himself never uttered a word he could not back up. His health had been failing for several years, but there was still fire in his words.
