Dinosaur flatulence

Friday, February 9th, 2007

Dana Rohrabacher, Republican member of the United States House of Representatives representing California’s 46th congressional district, in his rebuttal to the testimony of Susan Solomon, co-chairwoman of the Intergovernmental Panel on Climate Change (IPCC), and three of her colleagues and co-authors before the House Science & Technology Committee in today’s Hearing on the State of Climate Change, explaining the findings of their recently issued Climate Change report (IPCC Fourth Assessment Report).

Sure, pre-historic changes in the concentration of carbon dioxide in the earth’s atmosphere may have had natural causes, so why not this time? Except, wait, dinosaurs aren’t around anymore…

Rohrabacher kept bringing up the question of what percentage of carbon dioxide in the atmosphere is regularly caused by humans (he says 10 percent). Well, as far as I know that’s not the point. The point is that the concentration of carbon dioxide has increased about 40 percent over the last century and is now higher than it ever has been over the last 600,000 years. Oh, and according to an overwhelming majority of scientists that change is largely due to emissions caused by — you guessed it — us.

So, I want to see his list of “hundreds of scientists who honestly disagree” with the findings of the IPCC (not that global warming isn’t happening, but whether or not it’s caused by humans).

Interesting to see, though, how many of of the Republicans on the committee seemed to overall support the findings of the panel.

Alexander F. Mayer: The Many Directions of Time – Solving the Cosmology Puzzle (PDF, 15mb)

Maybe it’s time I brushed up on my physics (which, admittedly, is quite poor).

Waiting for solar

Thursday, December 15th, 2005

I’ve been shopping around for a car lately. It just occured to me that it’s the year 2005 and still no zero-emission, solar-powered, hydrogen-driven vehicles in sight. Come on, now! The technology has been around for years, last thing I heard.
