The global warming debate is so frustrating. The politicians latch on to the tinyiest piece of gloom and turn it into a vote winning or revenue making exercise. Let the scientist find out the truth before making knee jerk reactions.
I agree we should try to minimise where practicable our emissions a nd recycle if possible. But its pretty naive to think that for the relatively minute time we have graced this earth, we could really have such an effect on the environment.
Some say this pattern is a precursor to another ice age? Some say the sun is at its hottest for nearly 12000 years. That would warm us up!
The figures as previously mentioned speak for itself. Per head and distance travelled. Air travel is up there with the cleanest.
Otherwise, dust of the Cutty Sark and HMS Victory and lets all sail everywhere!!!!!
