Rotorbee,
You are right, and this could go on forever. For instance, lama sites a professor who can't get published as a source for perr-reviewed science. No win situation.
The funny thing is that I KNOW what science goes into the steel in the teeth of Lama's transmission - it was my business for 3 decades - and that is less sure than the evidence of global warming!
People must think that if there is any doubt as to the complete story, then there is no story. Such a shame, especially when the only real doubters are those who have something to lose (isn't that the case!)
When we shift to nuclear and hydrogen based fuels (as we must, or perish) then the carbon fuels - Oil and Coal - will become relics, and their stock will be mud. No wonder why they hire lawyers to argue against scientists!
