Michael Shellenberger, Environmental Progress: He has proven his dedication to truth about carbon dioxide from fossil fuels, commitment to humanitarian needs and protecting the environment. For all practical purposes, he has abandoned the extreme global warming alarmism of his advisor, James Hansen. Hansen has dedicated years to supporting a lawsuit to stop use of fossil fuels and force these energy companies to pay vast sums to the public treasury for having produced carbon dioxide, an essential molecule in the cycle of life. God bless Shellenberger. God .... Hansen.
