Carbon tally shows growing global problem
Several years ago I made the comment to a friend who happens to be a career scientist that sometimes the sky didn't seem as blue as it was when I was younger. More greenish, espeically noticeable at low sun angles. I can't remember his exact answer, but he said it had to do with the increased concentrations of carbon dioxide and other greenhouse gasses in the atmosphere, as well as certain man-made particulates. Would an increase in CO2 level (or other industrial pollutants) tend to make the atmosphere more opaque to certain wavelengths of light? Is ground-based astronomy eventually going to take a hit because of air pollution? --- Patrick Wiggins <paw@wirelessbeehive.com> wrote:

Nope, no data at all on wavelength blocking, at least that I could find with only a few minutes of free time to look the site over. I did find this interesting statement: "Is carbon dioxide a harmful air pollutant, or is it an amazingly effective aerial fertilizer?" Venus must be an incredibly fertile place, by that standard. --- diveboss@xmission.com wrote:

It was back when the female species roamed the planet. Over on Mars, the guy's were choking on methane. Of course, what would one expect when guy's get together on game day... ;)
