Al Gore thinks the logic of climate change deniers is akin to the reasoning behind the birther movement, which questioned the birthplace of President Barack Obama.

Speaking at a conference on Jewish social justice Gore said, “We just had the object lesson with the birthplace of our president,” he said to laughter. “The chuckles here are hard won because it is still an example of a question of fact being turned into a question of power.”
Gore used the recent birth certificate hubbub between Donald Trump and Obama to address the debate over climate change — if it is real and if it is caused by human activity. While the former vice president would like to capitalize on Obama’s handling of the birther debate, Gore has one disadvantage: He can’t just release a document to settle this once and for all.
The connection between climate change and human activity has been made through lengthy scientific studies and analysis. The proof is based on complicated measurements dating back centuries and analysis conducted by some of the smartest scientists in the world. That being said, climate science is complicated. It’s not a situation in which proof can be definitively released by the state of Hawaii at the request of a president. It’s not something that will just go away with a Monday morning press conference.
But Gore’s point is well taken. Whether it’s simple or not, the overwhelming evidence suggests that climate change is human-caused. And just like the birther movement had its deep-pocketed backers, the climate change denial movement has well-funded voices. Sen. James Inhofe (R-Okla.) and Lord Christopher Monckton are the first to come to mind. In the birther movement and the climate change denial movement, we have seen that noise trumps fact until those with facts on their side close the argument with a piece of paper.

Unfortunately for Gore, no simple piece of paper exists to prove his point. Maybe he should just run for president. After all, he has a birth certificate.
