James Hansen claims that "John Kerry is expert on the climate issue"; now claims that what he [Hansen] repeatedly called a "tax" is a "non-tax"; claims that a carbon "fee" "would reduce United States carbon emissions by 10 - 11 times more than the carbon carried by the Keystone pipeline"

Conservatives in the United States are beginning to recognize the merits of a carbon fee, which would be a non-tax, 100% of collected funds distributed to the public on per capita basis...After 10 years a carbon fee rising $10 per ton of CO2 per year would reduce United States carbon emissions by 10 - 11 times more than the carbon carried by the Keystone pipeline. The funds distributed to the public, 60 percent of the people getting more than they pay in increased prices, would spur the economy. The energy revolution would create millions of jobs. So don't despair re the tar sands. There are sensible alternatives. The common presumption that President Obama is going to approve the Keystone XL pipeline is wrong, in my opinion. The State Department must provide an assessment to President Obama. Secretary of State John Kerry is expert on the climate issue and has long been one of the most thoughtful members of our government.

In Hansen's 2009 Ways and Means testimony, he calls his "non-tax" a "tax" over and over and over.
