Oh dear i really shouldn't get into this, but I have to agree with the views that global warming is largely a con. I live in rural Somerset and when I dig in the garden (as infrequently as possible) i turn up fossil oyster shells and other evidence that this was once a tropical sea bed. Equally, I can find evidence of glacial valleys. So how did the latter get to the former in the absence of my 4x4 aand all the other things ?
Now I will admit that we may be accelerating the cycle between cold and tropical slightly, but "slightly" is the operative word. In the overall scheme of things changes in CO2 are natural. Again i will grant that CFCs may have influenced the holes in the ozone layer, but these are now gone - and your asthma inhaler is somewhat less effective as a result, as the CFC free propellants have other problems, but it this is a low order effect when seen against the overall historical cycle.
"clean air" is obviously beneficial to health (but not to black spot in roses) but let us not hide this undoubted benefit under the apron of "saving the planet"
I may as well end this - possibly my last as a Mod - by declaring my belief that nuclear power is the best short-term option: this is particulary ironic as HMG sold off the rights to current nuclear generation technology a few years ago and is now likely to have to buy it back.
