As scientists who have had their emails stolen, posted online and grossly misrepresented, we can appreciate the difficulties the Heartland Institute is currently experiencing following the online posting of the organization’s internal documents earlier this week. However, we are greatly disappointed by their content, which indicates the organization is continuing its campaign to discredit mainstream climate science and to undermine the teaching of well-established climate science in the classroom.
So although we can agree that stealing documents and posting them online is not an acceptable practice, we would be remiss if we did not point out that the Heartland Institute has had no qualms about utilizing and distorting emails stolen from scientists.
We hope the Heartland Institute will heed its own advice to “think about what has happened” and recognize how its attacks on science and scientists have helped poison the debate over climate change policy. The Heartland Institute has chosen to undermine public understanding of basic scientific facts and personally attack climate researchers rather than engage in a civil debate about climate change policy options.
These are the facts: Climate change is occurring. Human activity is the primary cause of recent climate change. Climate change is already disrupting many human and natural systems. The more heat-trapping greenhouse gas emissions that go into the atmosphere, the more severe those disruptions will become. Major scientific assessments from the Royal Society, the U.S. National Academy of Sciences, United States Global Change Research Program and other authoritative sources agree on these points.
Here’s the rest of the letter and the signatories:
What businesses, policymakers, advocacy groups and citizens choose to do in response to those facts should be informed by the science. But those decisions are also necessarily informed by economic, ethical, ideological, and other considerations. While the Heartland Institute is entitled to its views on policy, we object to its practice of spreading misinformation about climate research and personally attacking climate scientists to further its goals.
We hope the Heartland Institute will begin to play a more constructive role in the policy debate. Refraining from misleading attacks on climate science and climate researchers would be a welcome first step toward having an honest, fact-based debate about the policy responses to climate change.
