The best analysis I have seen attributes about 50% of global warming to human activity. The rest is natural causes like solar sunspots, etc. I guess high energy particles from sunspots disperse clouds, but human pollution helps make more clouds; but that is another discussion.
As to whether we can stop global warming or not; I use this analogy: If you are driving down hill in a car and the brakes fail, do you step on the gas? The least we can do is stop stepping on the gas. It's Friday and I'm caught up on my projects. ________________________________ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Ray Ayala Sent: Friday, 08 August, 2008 09:47 To: [email protected] Subject: Re: NMC, NPC; E85 article Aside from the ethanol-specific issues there are a couple of really simple concepts regarding 'green living' and global warming. As long as people produce more heat than mother nature can re-absorb (plant growth absorbs heat) we will be contributing to global warming. But observe that the majority of this continent was once covered in glaciers and most of them managed to melt away with no help from us. So is global warming a reality? Of course. Can we stop it? Not a chance in hell. And it's no surprise that the folks lobbying the hardest for a reduction in global warming are the ones that own the most expensive ocean-front real estate.
