If I've understood your question correctly, you are saying that global warming sceptics should not be allowed to make baseless claims?
Is that right?
Well, what about the numerous global warming alarmists who make equally baseless claims? The same should be true of them too, surely?
Reading between the lines, what I think you are also suggesting is that global warming is a big problem and that we should all be moving heaven & earth to try and fix it - and anyone who says otherwise should be silenced.
Is *that* what you believe? Very democratic.
The simple fact is that the causes of global warming are not fully understood - despite what you *think* you know - and despite what Al Gore might say in his Hollywood movie.
The truth is that though CO2 and other greenhouse gases are likely to be a contributing factor to global warming, they are not likely to be the only factor, and may not even be the main one.
If we were to move heaven & earth to stop all mankind's CO2 production, we my find it has little or no effect on global warming.
Will *you* pay me back what it cost me, if that happens?
BTW, feel free to check my sources!

In response to disgracedfish, below...
I *do* accept that global warming is real, what is in dispute is (a) the cause, and (b) whether it's going to be a problem. Much of the "evidence" that you refer to is being discredited - including the IPCC's report, as you would have known had you bothered to read my sources.
And your final comment, reversing my "Will *you* pay me back..." quote, is nonsense. By your logic we should go along with every crack-pot theory ever offered on any subject, on the off-chance that they may be correct. Some say that global warming is caused by God as His punishment for turning our backs on Him. Should we all get down on our knees and pray to Him, just in case? Hardly.
Also remember that, despite the global warming alarmists using words such as "catastrophe", "irreversible" and "tipping point", there is no reason to believe that we are in any imminent danger from global warming. Planet Earth has been much warmer than it is today in the relatively recent past, with no noticeable problems for humankind.
I believe the correct course of action is to wait and continue to study, until such time as we can come to a firm consensus on what action should be taken - something that is decidedly lacking at the present time.
In other words – look before we leap!

In response to disgracedfish' response to me, below...
At no point in my answer have I suggested that CO2 is not one of the causes of global warming. There is no doubt that CO2 is a greenhouse gas. Nor is there any doubt that CO2 levels are increasing in the atmosphere. Therefore it is logical to assume that this increased level of CO2 in the atmosphere would cause the planet to warm up a bit. But, the sixty-four thousand dollar question is; by how much? What I *do* suggest is that, as yet, no one has offered a conclusive, irrefutable answer to that question.
As Christopher Monckton points out, almost all the observed increase in temperature could have been caused by the sun - and he shows the calculations that lead to that conclusion - try them for yourself.
So you found Lord Monckton's article "quite lacking in the evidence discrediting department." did you? So, the fact that he shows "how the UN undervalued the sun's effects on historical and contemporary climate, slashed the natural greenhouse effect, overstated the past century's temperature increase, repealed a fundamental law of physics and tripled the man-made greenhouse effect." is irrelevant, is it? Or how about the infamous "hockey-stick" graph that completely deleted the Medieval Warm Period and was created by a computer model that produced "hockey-stick" graphs even when random data was fed in. Garbage in - "hockey-stick graph out!
As for the "pay me back" comment, "all we've lost is money"? Yes, billions of pounds of it if the global warming alarmists get their way. Frankly I need to be a bit more sure that action is really needed before I part with my hard earned cash.
You then say "I don't even want to consider what the cost may be." Given the state of the evidence I'd guess that the cost will be about the same as what the "Millennium Bug" cost us! (I wonder how worried you were about that storm in a tea cup?)
Ok, perhaps "crack-pot" was going too far, but the point is that the jury is still very much out on the issue, so it is still too early to start taking major action on the strength of the current evidence.
I must confess that I've never heard that people are more worried about how fast the planet is warming than how hot it will eventually get. I wouldn't worry about that though, because, of course, it's not heating up as fast as the predictions had us believe. It is for this reason that the alarmists are now claiming that the "missing" heat has been sucked up by the sea!
And finally, in answer to your last comment, here's what Lord Monckton said on the issue in his following article (http://www.telegraph.co.uk/news/main.jhtml?xml=/news/2006/11/12/nclim12.xml&page=2)...
"Shouldn't we take precautions, just in case? No. The "precautionary principle" kills. Example. DDT: correct solution, limit it in agriculture but allow indoor spraying against malarial mosquitoes. Actual solution: give the inventor a Nobel Prize, then say the chemical is cancerous (it's safe enough to eat) and ban it, especially for indoor spraying. Result, only this year, after 30 million and more have died from malaria, has the WHO agreed to recommend indoor spraying."
Or if you want another example of why we should leave well alone, try this... http://www.michaelcrichton.com/speeches/complexity/complexity.html It's a speech by Michael Crichton. It's long, but about a third of the way down he talks about Yellowstone National Park and the unmitigated disaster that ensued when humans tried to "manage" it. He sums up...
"Is this really the end of the world? Earthquakes, hurricanes, floods?
No, we simply live on an active planet. Earthquakes are continuous, a million and a half of them every year, or three every minute. A Richter 5 quake every six hours, a major quake every 3 weeks. A quake as destructive as the one in Pakistan every 8 months. It’s nothing new, it’s right on schedule.
At any moment there are 1,500 electrical storms on the planet. A tornado touches down every six hours. We have ninety hurricanes a year, or one every four days. Again, right on schedule. Violent, disruptive, chaotic activity is a constant feature of our globe.
Is this the end of the world? No: this *is* the world.
It’s time we knew it."
In other words; let's calm down and make sure there really *is* a problem, and, if so, what's *really* causing it before we start throwing vast amounts of money at it.

Ooops! Looks as though I broke the bank! I responded to disgracedfish again, but all the text in my answer disappeared! I'll post an answer via another user below to respond to him.
