The Heartland Institute is a Chicago-based free market think tank and 501(c)(3) charity that has been at the forefront of denying the scientific evidence for man-made climate change. The Heartland Institute has received at least $676,500 from ExxonMobil since 1998 but no longer discloses its funding sources.
Democracy is utterly dependent upon an electorate that is accurately informed. In promoting climate change denial (and often denying their responsibility for doing so) industry has done more than endanger the environment. It has undermined democracy.
There is a vast difference between putting forth a point of view, honestly held, and intentionally sowing the seeds of confusion. Free speech does not include the right to deceive. Deception is not a point of view. And the right to disagree does not include a right to intentionally subvert the public awareness.
