I don't know about their climate data, I just think their claims of the impact of carbon costs are pure speculation. If they had a calculator for determining temperature increase depending on carbon output, it would be more credible. They are piping two complex system into each other - economic and climate. At least economics are not understood well enough to really make such predictions. And if the output of the economic model is unreliable, so is the result of the climate model.
