My tuppence worth...like him or not, the al gore film I felt was particularly well balanced, does not deny that warming is cyclical,,but points out how much more warming etc has been caused by people and actually shows in idiot proof terms how, and why...it's easy to dismiss people like him as failed politicians and drum bangers with their own agenda BUT.."gore was independently wealthy before his political failure...he will be financially secure thru his pension as ex vp of America also....and it is pretty much political suicide what he continues to do..so I doubt it's self serving....if you haven't watched it please don't judge on the other knee jerk reactionary stuff that has been made. It's a grown up film with honest, clear opinions and facts.
Perhaps this is a bit contentious for some but I honestly believe that global warning deniers will become as historically decried as holocaust deniers. This is happening.....can we stop it...NO....can we slow it down and try to get it back to its natural, cyclical rhythm...yes, to an extent....the Kyoto treaty etc...is important and the fact that America still had not ratified it in 2008 is indicative of the land of the free's wholesale disrespect for everyone else's freedom....but then, we knew that, didn't we...
As for wind farms etc, I don't know enough to argue but from what I have read, I broadly agree with you bluesman, this is blind alley technology and akin to shutting the gate after the horse has bolted...the real futer lies in renewables, perhaps tidal energy generation and wind power does contribute, but not nearly to the level that some would have us believe....the technological advances made by diesel and petrol engineers is incredible, and electric cars have made bounds that make our present cars slow evolution from Karl Benz' first horseless carriages to the Maclaren p1 akin to the progress of a one legged man in the world ***** kicking championship....ie slow, and unsteady....if electric vehicles keep improving at this rate they will become viable for all
Now, im off to have a 50 mph , 36 mpg cruise in my ls400 and LI will feel good because I am not contributing to the created man made consumer cycle....
