Joph. You're ability to "read scientificeese" isn't that good apparently. You quote things, but don't really read them for what they actually say. Scientists, unlike politicians, say *exactly* what they mean. Not one bit more. Not one bit less. You cannot quote a scientific fact that sounds kinda like something similar and infer a larger meaning.
Science in Dec. 2004 wrote:
In its most recent assessment, IPCC states unequivocally that the consensus of scientific opinion is that Earth's climate is being affected by human activities
Affected How? To what degree? How much of this is responsible for the increase in global temperature over the last century? See. Scientists will say this if there is
any measurable impact, no matter how small.

IPCC is not alone in its conclusions. In recent years, all major scientific bodies in the United States whose members' expertise bears directly on the matter have issued similar statements.
Similar statements? Where's the statement saying that human activities are the primary cause of the raise in global temperatures over the last century? I asked you to show this *one fact*, and you haven't done it yet. This statement, and other "similar statements" could mean anything Joph.

See, this is the difference between you and I. I am actually linking to evidence and you're making up shit to minimize the issue.
No. The difference is that I read what is *actually* written. You interprete what you read in order to convince yourself that it means what you want it to.
I'll ask again: Show me a quote from a peer reviewed scientific source that says unequivicably that human activity is the primary cause of the increase in global temperatures over the last century. Can you do that?

Silly me. I thought that the validity of the science he's using to support his agenda reflected directly on whether or not it was "good policy". Apparently I was alone in this.
No. It's good policy if it takes all the factors into consideration. What we're seeing right now is *one* factor that is being exagerated into a "convenient lie" (to paraphase Gore), in order to pursue a specific political agenda.
The NAS in "Climate Change Science: An Analysis of Some Key Questions" wrote:
Greenhouse gases are accumulating in Earth's atmosphere as a result of human activities, causing surface air temperatures and subsurface ocean temperatures to rise.
To what degree? Could you quote the *entire* paragraph instead of one sentence (or provide an online source that the rest of us can read). Again. This could mean anything. How much of a temperature increase? Is this a statement of findings? Or a hypothethical model? We can't tell from this quote Joph.
The NAS in "Understanding Climate Change Feedback" wrote:
Over the next century it is likely that forcing of the climate system by human activities will greatly exceed changes in forcing caused by natural events.
Wait! So "it's likely" that forcing caused by humans will exceed changes resulting by natural forcing in the next century? What about the
last century. Isn't this the question? Again. Is this a finding of fact? Or just a hypothesis? Since they're making a prediction, this can't be fact. It's a guess.
What is this guess based on? Who's model? Where did it derive its data?
I'll ask again: Where's the quote from the peer reviewed paper stating as a matter of absolute fact that human activity is the primary cause of the rise in global temperatures over the last century?
I've asked this over and over. Yet you keep giving me quotes that are only peripherally related to the question. You seem convinced that every single peer reviewed paper on the subject concludes that this is happening, yet you can't seem to find it anywhere, can you?
All I'm saying is that it's prudent to not throw the baby out with the bathwater here. Should we work to reduce global emissions of greenhouse gasses and pollutants? Of course we should. But should we overfocus so much on one aspect of the environment and one possible problem that we lose sight of everything else in the process? I think not. But when folks argue this issue like it's a complete conclusion that unless we make some dramatic change, we're all in for a disaster, I have to counter that by pointing out all the other ways we could also head for a disaster.
IMO, we're far more likely to head into a global period of starvation and suffering in the next 50 years as a result of economic problems then climate problems. I could certainly be wrong. But I doubt it. We're *already* seeing pretty heavy rates of starvation in many parts of the world. And this is with a climate that is nearly perfect for growing enough food to feed the world. I'm sorry if I put the climate issues in perspective where many people do not.

As for the rest of your guesswork, I again invite you to submit the evidence to your claims.
You're demanding that I prove a negative Joph. I don't have to prove that you're wrong. You have to prove you're right. My only argument here is that the "science" actually has not proven that human activity is the prime cause of the temperature increase we've experienced over the last century. That's it. I don't have to "prove" that. Because in this case I'm advocating *against* taking massive and draconian action as a result of something that I see as over exagerated science taken to the most ridiculous political extremes possible.
You're the one who keeps saying that humans as the "cause of global warming" was a proven fact. I'm just asking that you provide the proof. Not people's opinions or beliefs. I want to see an actual paper released with a quote that says unequivicably that humans are the prime cause of *past* global warming (ie: the temperature increase over the last century). Not guesses about the future. Facts based on data on which scientists have placed their reputations and research.
Should be easy if it's so obvious a fact to you...
