Basically every organization that has looked at the issue and built a serious model has reached the same conclusion. From early studies done by engineers at oil and gas companies, to research undertaken by skeptics, the message is the same: we're not in Kansas anymore, and we're running out of time to turn around.

All of the models you mention use the completely incorrect math for feedbacks that will worsen warming caused by CO2. They literally all use the 3K per doubling figure. Despite it being proven wrong mathematically, and proven wrong historically as these models have all been wrong for the last 20 years of observed data.
As soon as you get him to address the error, let me know.
>I'm sure you're aware that Monckton has no formal mathematical training
Good thing it has been confirmed by mathematicians like I pointed out then huh?
>that his complaints against terrestrial climate models include the "fact" that they didn't predict warming on Pluto.
I am not interested in strawmen, I am interested in the simple, verifiable, objective claim being made. Every single climate model used to promote climate change hysteria uses the same feedback equation. They all make the same error, using the temperature difference rather than the temperature as they should. Using the correct data to calculate the feedback, those climate models produce only 2 degrees warming by 1200ppm CO2 rather than the 6 the IPCC is promoting. And they match with the last 20 years of data, while using the wrong figures as the IPCC promoted predictions do gave us hugely overestimated warming for the past 20 years. No amount of "I don't like things I pretend that guy said before" changes this. Math does not care about what anyone says or how anyone feels. The entire warming hysteria relies on the feedbacks, the IPCC and CIMP both agree that direct warming is only 1k, and claim feedbacks make it 3k. Without the incorrectly calculated feedback, there's simply no justifying the hysteria.
