GLOBAL WARMING - pretty much an undisputed fact to one degree or another.
Caused by man - BULL - total and utter BULL. I don't think anyone claims it's caused by man, it's caused by the sun. Without it the earth would be an uninhabited snowball whirling silently in space - but we can nudge that effect slightly, without even trying.
Added to by man - probably, but not that it bothers China or the Yanks. If we went back to the stone age for 10 years in the UK, our efforts would be wiped out by the above in a week. Sad but true. "So I suppose you're saying that means we should not bother here in the UK" ...... sigh ....whatever... I know, it's disheartening, but someone has to take the lead if the rest are to follow; and if we're among the front runners, we stand a chance of being well positioned when the oil industry is being succeeded.
What has had an effect and the graphs match perfectly are ...... solar flares and spikes in our global warming. So we need to turn the sun down a bit ...... If only we could, that would be so much the easiest solution. As we can't, our only hope is to manage the things we can, like not increasing the greenhouse effect.
I really must do some work at some point today.
