A new paper by the computer scientist and entrepreneur John Mashey, (attached) digs ever deeper (and in an increasingly well-organized way), into the morass of deception and disinformation that has characterized the recent climate conversation.

Mashey never uses the word "lies," but somehow it seemed an appropriate illustration of what he finds underlying the recent campaign against climate science, scientists and anyone who respects their work.

This and Mashey's previous paper point an unflinching finger at corporate front groups and free market think tanks that have worked so hard in the last two decades to spread confusion about climate science and to block public policy that would regulate the use of fossil fuels.

Mashey makes a compelling case that Congress has been misled in the process - which is an offense against the democracy that think tankers claim to love (in addition to being a felony).

For a visual reckoning of the kinds of think tanks involved, Mashey has populated a Google Map locating the major and minor players - although care should be taken to sort out those tanks that have the worst record in all of this - say, the George C. Marshall Institute, the Competitive Enterprise Institute, the Cato Institute and the Heartland Institute - from some that are just going along with the pack.
