Good idea in your opinion to risk that the "theory" is wrong, whatever the quality of the science on which they are based, than to risk that it is right.

MAJOR ULTRAVIOLET RADIATION INCREASE MEASURED IN ALASKA

First Analysis of Ground-Based UV-B Data

Ozone Depletion the Culprit



Washington, D.C., March 16-- A major new study published today detected major increases in harmful ultraviolet-B (UV-B) radiation reaching the ground at Point Barrow, Alaska. Increases ranged from 3-10% per year between the years 1991 and 1996 in this populated region in all daylit months except June. The Geophysical Research Letters study, "Evidence for Increasing Ultraviolet Irradiance at Point Barrow, Alaska," was published by Kevin Gurney from the University of California, Santa Barbara.

This is the first ground-based measurement of major ozone depletion in a populated region. Most of the severe depletion in the past was measured over the South Pole in Antarctica. Both the rate and magnitude of the decline over Alaska are dramatic and unexpected.

This is the first ground-based measurement of major UV-B radiation increase in a populated region. Most of the severe ozone depletion and consequent UV-B increase in the past were measured over the South Pole in Antarctica. Both the rate and magnitude of the decline were dramatic and unexpected.

The ozone layer shields the surface of the earth from damaging UV-B radiation. UV-B is known to cause skin cancer, cataracts, and immune suppression in humans. It is also biologically harmful to plants and animals.

This study is particularly worrisome because snow and ice on the ground in Alaska reflect UV-B, thereby intensifying the impact of increased UV-B due to ozone depletion.

"This study shows that ozone depletion currently poses its greatest threat ever, just when policymakers are trying to tell us that the problem is solved." said John Passacantando, Executive Director of Ozone Action in Washington, DC.

especially as the Clinton/Gore recession takes hod of our economy.

The '90's boom had nothing to do with Clinton/Gore, and nothing to do with Reagan/Bush either. The current slide - it isn't a recession yet, and may or may not become one - has nothing to do with Clinton/Gore either. Political vagaries have very little real effect on business and market cycles; other factors (in this case, demographics and technological cycles) are far more significant.

It should also be pointed out that the current stock market "crash" is not a crash at all, it is simply a restoration of sanity in valuation of certain sectors. If you don't believe that, look at a 10-year chart of any major index. We are still way above 10-year median levels.

Clinton did not make the sky fall. The sky isn't even falling. There is no special need for melodrama, even if it's ideologically gratifying.
