The source of global warming is up there, but not visible: the greenhouse gases that are warming up the planet.
The solution is up there, too: energy from the sun. So says Robert Arthur Stayton in his book Power Shift: From Fossil Energy To Dynamic Solar Power.
He shoves aside the concerns about expense and economic dislocation, and paints an optimistic picture of a future in which we get 100% of our power needs met by the sun. The author joins us to lay out his vision.
