Rubio: Climate Change Isn't Manmade

This weekend Sen. Marco Rubio declared that he doesn't believe "human activity" is causing climate change. The Washington Post editorial board reacts:

It is one thing to invite a debate about the best policy to address rising global temperatures, a problem no country can tackle on its own. It is another to dismiss the evidence that “these scientists” have compiled — “a handful of decades of research,” Mr. Rubio derisively called it — to show that humans are driving much of that warming. On Sunday, Mr. Rubio insisted that he is ready to be president. We hope he does not count sidling up to climate change denial as a qualification. It is quite the opposite.
