The first sequence of the 3-hour series introduces some unexpected characters and places, presenting what our host, geoscientist Richard Alley, calls the “twin stories of climate and energy.” We meet Annise Parker, the Democratic Mayor of Houston TX (re-elected since this program first appeared on PBS on Earth Day 2011) and David Titley, a Navy Rear admiral, interviewed in dress whites in the Naval Observatory in Washington DC. Scenes from around the planet show many different kinds of energy usage (cars, trucks, lighting) and the many different kinds of energy resources (wind, solar, gasoline, biomass, waves/tidal.) Richard Alley introduces himself as the on-camera host, in scenes from the filming of the project—in a helicopter above the Franz Josef Glacier in New Zealand, and striding across the dunes near Yuma, Arizona. He reveals some of his personal history, and his hopes for the futures of his daughters and his students at Penn State, where he teaches. Those hopes rely on smart choices about energy, which can result in reducing adverse impacts on Earth’s climate. And that’s exactly what the remainder of the first program, and the next two episodes, deal with in greater detail.
