Geography

I was heartened just now, arriving to my office at Luther around noon, to see the Geography 100 instructor holding a globe as he spoke. He seemed to be turning it.
I'm tempted to sneak across the hallway right now and eavesdrop on what they're up to:
He's speaks quietly, gesturing with one straight arm. As high as it gets he says.
I've left my office door open in hopes of catching more. He's do doubt aware that scientists are looking for other earths, in case we blow up this one. Across the hall, he's the only one I've heard speak. Large variation in solar radiation gets a louder tone.
