All that and not one single piece of rebuttal. Are you a "Climate Scientist" TM?

Are you ?

"Climate scientist says costs of implementing UN report aren't worth it
"This is not just any old climate scientist. This is Yale economist William D. Nordhaus, who according to the New York Times, "has spent the better part of four decades trying to persuade governments to address climate change, preferably by imposing a tax on carbon emissions." In recognition of his work he was awarded the 2018 Nobel Memorial Prize in Economic Sciences.

Why he is skeptical about the cost-benefit ratio of steps that the UN's Intergovernmental Panel on Climate Change is explained in "New Nobel laureate William Nordhaus says the costs of proposed CO2 cuts aren’t worth it.":

    The IPCC report significantly underestimates the costs of getting to zero emissions. Fossil fuels provide cheap, efficient power, whereas green energy remains mostly uncompetitive. Switching to more expensive, less efficient technology slows development. In poor nations that means fewer people lifted out of poverty. In rich ones it means the most vulnerable are hit by higher energy bills..."

So even a Nobel winner who has been a champion of CO2 mitigation doubts its cost effectiveness. Nordhaus was the father of the 2C limit.
