What I have discovered in 20 years of studying the universe, from here to there to everywhere, is that the universe is complicated, and when things happen, it is almost never like ‘A happened and therefore B’. No, A happened and therefore B, C, D and E, but then there is this thing F, and that had a 10% effect, and that prompted G to go back and tip over A, and it is always like this – everything is interconnected. And so a lot of these far-right fundamentalist religion people, and a lot of these people who are anti-global warming, anti-evolution, anti-science, what they do is they take advantage of the fact that things are complicated, and their lives are based on things being simple – if we do this, then this will happen – if we invade Iraq, we will be treated as liberators, if we pray, then good things will happen, and this stuff is wrong. But we have a culture where people are brought up to believe in simplicity, and if A then B. And so when you point out that scientists say the earth is warming, but we had a really devastating winter this year, then these people will say “oh, obviously global warming is wrong”. No, global warming can cause worse winters locally. It’s complicated. But people don’t want to hear “it’s complicated”, and boy, the conspiracy theorists and anti-scientists take full advantage of that.

One thing I try to point out to people, and Dick Lindzen has pointed this out in the past, too, is that, as most of you probably know, about ninety percent of the earth’s greenhouse effect is water vapor, then carbon dioxide, methane and some trace gases. The water vapor con-centration in the atmosphere goes up and down quite a bit, but it is self-regulating. Things don’t get too warm before precipitation systems suck the water vapor out again. I don’t understand how we can know how much warming there will be with global warming until we understand how precipitation systems change with warming. We don’t under-stand that, and I have papers from modelers who have said the same thing. Modelers don’t like to talk about what they don’t know. So until we understand these natural proc-esses that remove the earth’s primary greenhouse gas, water vapor, from the atmosphere – which is a self-regulating part of the earth keeping a constant temperature – I don’t think we can predict how much warming there will be due to increasing CO2. It is a mat-ter of faith again, I think. We are not saying that we don’t believe that there can be sig-nificant global warming. As John said, if you add CO2, something has to change. But things are changing all the time anyway. The big question is: So what? How much is it going to change, compared to other things? And what can you do about it?

It should come as no surprise that there is no shortage of environmentalist exaggeration and half-truth that also "misleads people about climate change". After all, professional environmentalists and climate scientists might lose their jobs if the global warming problem was to ever go away. (...) As a result, everyone in the global warming debate is biased. People can expect that corporations will emphasize research that supports their opinions and goals, while environmental lobbying groups will do the same. Everyone has financial motives, and government-funded scientists and environmentalists acting as if they own the moral high ground is an increasingly tiresome pose.

I believe global warming is grossly exaggerated as a problem. It's a real problem, but it's nothing like as serious as people are led to believe. The idea that global warming is the most important problem facing the world is total nonsense and is doing a lot of harm. It distracts people's attention from much more serious problems.

 

Freeman Dyson

 

Algore has conferred upon himself the biggest ticket of his life in the Nobel Prize. Nothing says "I'm smart" quite like an award from a bunch of socialist Swedes, in the community that Algore runs around in. Much the same way as the Nobel Prize gave credence to Jimmy Carter's anti-Semitism and Yasser Arafat's peace campaign, Algore now has that same credibility for the religion of global warming. In my mind, in a fair and honest world, the recipient of this award — the reason for this award being awarded, manmade global warming — should debunk it, because the Nobel committee has lost all credibility long before they gave this award to Algore and the United Nations. Sadly, this will probably, in the minds of the ignorant and those who pay scant attention, lend convenience to the whole phony hoax that is manmade global warming.

 

Al Gore

 

We simply must do everything we can in our power to slow down global warming before it is too late... The science is clear. The global warming debate is over.
