Michio Kaku on climate change

At CNN Christiane Amanpour has an interview with Michio Kaku: The climate change debate is over. The video goes for about five and a half minutes.

In the fierce and sometimes ugly fight over global climate change, we finally have an answer coming from the earth itself: the weather is telling us climate change is here and we are causing it. This summer, there have been relentless - droughts, wildfires, melting glaciers and unprecedented storms – all happening at the same time. And around the world people are demanding something be done about it. Even in the United States, ground zero for climate change denial, six in ten Americans say they believe it is indeed happening. But political leaders are missing in action – cowed by a vociferous climate change denial club, which is actually now shrinking faster than the polar ice caps. Watch the video above to see theoretical physicist Michio Kaku explain just how the world is giving us signs that climate change is already happening.
