Iam going to look at the Conspiracy theory's just for a moment. This one in particular comes into focus on the grounds that greedy capitalists just might of set this all up as this link spells out.

What do you think of this?

So its fair to say that human impact is the main cause of AGW. So which ever way you look at it, mankind is having an effect.

So therefor its true in what I said.....We have just sped up the processes realistically. And see the more that human population expands, The worse it gets for all living things.

Oh and you dont need to gamble with that fact.

Volcanic outflows have a greater effect on this planets livability and the earths self balance to sustaining life than a bunch of publicly funded windbag academics.

"so let me get this straight; you want me to provide evidence that Humanity is devastating the whole biosphere"
-Squeers

Aye. Journal articles from Nature and Science are preferred, but as long as the journal isn't dodgy then it's all good.

"How about you now explain to me "your" notion that we are not harming the biosphere, and are not subject to ethical considerations?"
-Squeers

I've never made this claim, so there is no onus on me to prove it. You can't see it, but I'm rolling my eyes.

"I've put up tons of substance on this thread"
-Squeers

Liar. If you had, we wouldn't be having this discusion.

Copy, George Papandreou, the Greek prime minister, said new European-wide taxes might now be needed to fund bail-outs.

“We need a mechanism which can be funded through different forms and different ways,” he said. “My proposal is that taxes such as a financial tax or carbon dioxide taxes could be important revenues and resources for funding such a mechanism.”

Deep Blue, "So its fair to say that human impact is the main cause of AGW"

No it is not. The point I have made above is that there is no scientific basis for asserting that human emissions have any measurable effect on climate.

Despite the predictions of the alarmists, the increase in CO2 in the atmosphere has accompanied global cooling, not warming. There has been no warming since 1998.

Whatever effect human emissions have is insignificant.

I invited anyone who thought otherwise to submit a scientific basis.

No one has, because despite the outlay of $100 billion in research, there is no such scientific proof.

Your assertion is nonsense Deep Blue.

Riz and Riz Too: Tweedledum and Tweedledumber.

I do not appreciate being called a liar. Whatever my failings I am not that.

There is a world of "evidence" out there, both phenomenal and documented, for you to consult for yourself(selves), but I sense your state of blissful ignorance is not disposed to be educated.
So a big Raspberry to you!
