It is no use, Geezer, trying to apply logic to this argument. I have long since given up and have now turned my attention to the ridiculously ineffective (but hugely expensive, very inconvenient and sometimes dangerous) measures which are proposed to combat this supposed problem.
It is widely accepted, even among “experts”, that only 4% of gases which are allegedly soon to bring about the end of life as we know it are the product of man’s activities. The rest come from volcanic activity, reactions that take place in the sea and other non-human origins. It has never been satisfactorily explained how the planet can cope with variations in the latter but not the former. We are asked to accept (because “the debate is over” or “the science tells us” or Lazy Gun’s assertion “Of course, without doubt - How anyone can think otherwise is beyond me.”) that the huge variations in things like the volcanic activity that has been mentioned can somehow be catered for, but the relatively small variations (in absolute terms) in manmade activity cause the hysterical responses we have witnessed in recent years.
There are signs, admittedly very small signs, that the worm is beginning to turn and some commentators and indeed politicians are starting to show signs of the heresy which is levelled against climate change deniers. This is good news, but it may be too little too late. The damage being done to economies and environments and the threats posed to (particularly) European nations’ energy security is immense and will take decades to reverse. People will find that the cure is far more unpleasant than the supposed disease.
If climate change is evident and if humans are responsible (two very big “ifs”) it will not be reversed by European nations changing their light bulbs and covering the continent with useless wind generators.
