Surely question 2 should be quantified - i.e. "How much of an important factor are human influences warming?" with a subsidiary question "Of the human influences, how much is due to CO2?".

Unfortunately Nordhaus quotes the IPCC as saying "“No climate model using natural forcings [i.e., natural warming factors] alone has reproduced the observed global warming trend in the second half of the twentieth century.” which says in other words human influence is >0

A typical warmist exhortation.

Starts with convincing and undisputed scientific arguments, but rapidly drifts into mass production of straw men like "Lysenko" and "Madison Avenue".

I stopped reading at The big money in climate change involves firms, industries, and individuals who worry that their economic interests will be harmed by policies to slow climate change.

No honest person could have written that.
