Climate change '5pc threat to economy'

Here.

Excerpt:

The Global Integrated Assessment Model (GIAM) shows Australia's economic output would fall 0.6 per cent by 2050 below the level it would be without climate change, and five per cent by 2100.

I have absolutely no faith in the predictive ability of these models.

However, if carbon dioxide is going to result in human extinction this century, I'm surprised that it would only knock 5 percent from Australia's 2100 economic output.
