Great! We’ve reached our goal of 80,000. Can we 100,000 people to stand up to Heartland?

Are you part of the “radical fringe”? According to an ad campaign by the Heartland Institute, if you believe in climate change, you’re a radical on par with the likes of Osama bin Laden, the Unabomber, and notorious mass-murderer Charles Manson.

An ad campaign planned by the corporate front-group the Heartland Institute — which is funded in part by Microsoft and Pfizer – features the faces of these notorious killers alongside the phrase “I still believe in Global Warming. Do you?”

Tell Microsoft, Pfizer, and Heartland’s other funders to stop funding Heartland and its dirty climate change denier smears.

Even as people are literally dying from increased flooding, drought, freak storms, and other climate impacts around the world, the fossil fuel industry continues to deny that climate change even exists. Their strategy has been incredibly effective — they’ve stopped the US from taking any serious action to end its addiction to oil and coal, which in turn has made it impossible for the world to reach a global climate treaty. And Heartland, a key climate change denier, also depends on Microsoft, Pfizer, and other corporations who claim they believe in climate change out of one side of their mouth — while simultaneously funding an organization that runs despicable ads like these out of the other side. That’s why we’re joining up with our friends at Forcast the Facts to call for corporations to stop funding Heartland.

The Heartland Institute has a long history of playing dirty. Last year, Heartland was caught trying to sneak industry-written pro-coal propaganda into elementary schools, and previously they have acted as hired guns for the cigarette industry, distributing a paper titled “Joe Camel is Innocent!”.

Corporations have begun fleeing from Heartland. In March, General Motors announced it would no longer fund Heartland. Just yesterday, Diageo — the company behind Guinness, Smirnoff, Johnny Walker, and other brands — also announced they were pulling funding. Now is the time to give Microsoft, Pfizer, and Heartland’s other funders — many of whom have explicitly stated they care about fighting climate change — a push to follow GM and Diageo’s lead.

Help us stand up to the business of climate change denial, and call on corporate America to pull its money out of the Heartland Institute.

Sign our petition to Microsoft, Pfizer and others corporations: Stop donating to Heartland.
