Unwitting humanity has been saved by the sea. About 90% of the extra heat from our greenhouse gases was absorbed by the ocean, like a giant air-conditioner. But the power could be cut off soon, as we hear from our second guest Keith Moore. We are setting a hot stage for coming centuries. From New Zealand, Dr. Kevin Trenberth has worse news right now. For a third year in a row, world oceans set a new heat record, reaching levels not seen for over a million years. Trenberth says the hot ocean is dialing up strange extreme weather all over the world. Expect the unexpected.
