Apollo astronaut Jack Schmitt speaks out against human-induced global warming

Jack Schmitt, the only geologist to walk on the Moon during the Apollo program, has spoken out against the idea of human-induced global warming.

Quoting Schmitt from the story:

"Not that the planet hasn’t warmed. We know it has or we’d all still be in the Ice Age," he said. "But it has not reached a crisis proportion and, even among us skeptics, there’s disagreement about how much man has been responsible for that warming."
