RE: Nuclear Power, Trivializing Global Warming

["Rick Orthen" <rorthen@cecinc.com>]

"June 2, 2004 - Innovations Report - Concerns remain about UVB damage to

amphibians - The exposure of amphibians to damaging levels of ultraviolet-B

radiation in sunlight is likely a significant part of global amphibian

declines, researchers say, despite some recent suggestions to the contrary

and a scientific controversy about what role UV-B actually plays in this

crisis. Scientists from the United States, Canada and Spain have outlined

their understanding of UV-B's biological effects on amphibians in an article

in Ecology, a professional journal. In it, they respond to some recent

studies that have called into question whether UV-B radiation is causing

severe health problems or mortality in amphibians. "At this point, we

believe the broad body of research conclusively demonstrates that UV-B

radiation can cause damage to many species of amphibians at every stage of

their life cycle, from egg to adult," said Andrew Blaustein, a professor of

zoology at Oregon State University and the lead author on the Ecology

commentary. "It appears the damage may be even worse than we originally

thought a few years ago, and it's clear that rising levels of UV-B

radiation, which could be caused by erosion of Earth's protective ozone

layer, can play at least a part in the amphibian declines we're seeing

around the world."
