After giving a speech at the United Nations about climate change, Michael Bloomberg told reporters that stopping global warming "is just as important as stopping nuclear proliferation" and "fighting terrorism."

When I asked him to elaborate, Bloomberg said the dangers of terrorism and nuclear proliferation could be felt instantly, while the--also enormous--danger of global warming could be realized over a long period of time.

Bloomberg concluded by saying the presidential candidates aren't talking about this issue and that "we have to stop this craziness of destroying our planet."
