the ozone hole
Continuing on the thread drift.....
I recall about 12-14years ago, scientists were certain that CFCs were causing an ozone hole. In fact they stated that even if all CFC production was ceased, because of the time it takes for them to get to the ozone layer to destroy it, the hole would get bigger till 2050 - then reduce. But because of economics, China and India, as 'developing nations', were exempt from reducing CFC production.
So the scientific consensus was that the ozone hole was going to get bigger and bigger for decades to come.
Ten or more years later....what ozone hole????
I am always wary of scientific consensus...but I do agree with the research that shows if dinosaurs hadn't driven so many gas guzzling cars and 4WDs they wouldn't have altered their climate and be extinct!
