Environmental activists have made the shaky claim for several years now that the debate is "closed" on whether man's burning of fossil fuels is disastrously heating up our planet.
They say there is no debate at all. What's more, they predict catastrophe if man does not radically reduce the use of fossil fuels -- although the resulting loss of energy production would seriously harm both humans and the world's economies.
But it's interesting to note that scientists are now questioning a view that has much stronger -- and much longer -- support than global warming theory.
The Associated Press reports that "One of the very pillars of physics and Einstein's theory of relativity -- that nothing can go faster than the speed of light -- was rocked ... by new findings from one of the world's foremost laboratories. European researchers said they clocked a ... subatomic particle called a neutrino going faster than the 186,282 miles per second that has long been considered the cosmic speed limit."
In other words, a fundamental, long-held belief about physics may prove to be wrong. So we have to wonder: Is it really sensible to declare that the debate over far less certain global warming theory is "closed"?
