This looks very very very much like [EE] to me. Just not about Bimota centre hub EE. A discussion about GW will, alas, rapidly decay into a political-religious bun fight with all thinking missing. Which is a shame. GW, ie human caused warming, *IS* *DEFINITELY* real. :-) *HOWEVER*, the relative contribution, effect and avoidability of human contributions is still very very indeterminate. The true engineering is/would be in gaining an understanding of the above. Alas, the gravy train is too gravied and the nay sayers too say naying for this to occur until it's too late and/or we find out it doesn't/didn't matter. I personally *suspect* that present trends are towards vastly overdoing the response, BUT I may very very well be wrong. Being wrong is not a good choice when it's the whole system one is playing with. So "precautionary principle" says we should bite the bullet, feed (alas) the gravy train and do really really really goos science to find out the truth. Really really good engineering plays a necessary supporting role to this.
