About 500 million years ago, when we had an explosion of life, we had 0.7% carbon dioxide in the atmosphere.

It's gone down to 0.04%.

Where's it gone?

It's gone into the rocks, into sediments.

Now, during that 500 million years, we've had a couple, three major ice ages, yet carbon dioxide has been going down over time.

So there's no relationship between temperature and carbon dioxide.

Well, you used the word believe, and that's a word of religion and politics.

It's not a word of science.

And they believe it because that's the way of putting bread on the table.

Now, I've had these people in various departments that I've run.

And these people are mainly mathematical modelers.

They're eminently unemployable.

They are able to get grants from governments by scaring people witless, and the government throws them a few shackles to keep them alive.

And they base their life on a model, looking at what might happen in the future, and if something goes wrong, they'll redo the model.

Now, we've had 40 years of models now, and of the 102 major models we have, not one of them

has told us what we've measured over the last 40 years.

So they don't work because they make one assumption, which is invalid, and that is that carbon dioxide drives temperature.

Now, there's not one scientific paper out there, and this is a big call, but you can check it out.

There's not one scientific paper there that demonstrates that human emissions drive global warming.

If there were, you'd never hear the end of it.
