Climate polarization on steroids yields to satire

On May 4 The Heartland Institute rolled out a provocative billboard campaign in Chicago.

It was accompanied by an equally provocative press release explaining the reasoning behind the billboard.

The people who still believe in man-made global warming are mostly on the radical fringe of society. This is why the most prominent advocates of global warming aren't scientists. They are murderers, tyrants, and madmen.

Although the Institute removed its provocative billboard after only 24 hours, this didn't stop the tit-for-tat retaliation.

Meanwhile, the folks over at Grist have opted for a more satirical approach.
