I'm not as cataclysmic as Lester Brown, it sells books, as the earth has been coming to an end since man first applied quill and ink to paper or papyrus. Or a stone to a clay tablet.
In the 00's, it is Global Warming.
In the 90's, it was a huge hole in the Ozone Layer.
In the 80's it was Global Cooling - and I'm glad that trend reversed, it was getting nippy.
In the 70's it was DDT and Dioxin (Rachel Carson's Silent Spring).
In the 60's it was Mutually Assured Destruction of US - USSR nuclear war.
In the 50's it was Godless Communists running rampant
In the 40's it was WW2 and the other Axis of evil.
In the 30's it was The Great Depression.
Man, there's ALWAYS an Apocalypse around the corner - it's wonder any of us here are alive - in light of the overwheliming odds against sustained life on this planet.
I don't believe for a minute that Global Warming induced by Greenhouse Gas is based in solid science.
I have seen the ice caps recede, and miraculously the polar caps on Mars also have withered.
My limited (peanut sized) brain may not be able to get wrapped completely around Al Gore's Inconvenient Truth - but I'm guessing approximately ZERO human made Carbon Dioxide is causing the Greenhouse Effect on Mars.
Increased radiant solar energy? I'd buy that. There are Solar Minimums and Maximums in sunspot activity, and these affect solar energy output.
But folks, you can't tax sunshine, yet - so that form of science has no political value.
Check out Ben Stein's "EXPELLED". We have world renowned Meteorologists and Climatologists who have been "expelled" by universities because their academic findings do not support further study of "Global Warming" science which has cost some universities massive government grants.
Politics affects Science. If you don't agree, ask yourself... is Al Gore a Scientist?
Anyway -(stepping down off the soap box)- junk science or not. It's good for our industry.
