Sports remain a great metaphor for life's more difficult lessons. It was through athletics that many of us first came to understand that fear can be tamed; that on a team the whole is more than the sum of its parts; and that the ability to be heroic lies, to a surprising degree, within.

In every sport there comes a moment when a spell of bitter weeping seems like a fair recess from whatever tough work is going on. It's only the steeliest among us who can fight the urge to turn negative-who instead will make contact and redouble her efforts. Call it grace under pressure. Call it grit....call it excellence.

People think with climate change what's going to happen is things are just going to get hotter. But that isn't really the whole story at all. One of the things that has happened in the past when the climate has changed a lot is that the glaciers melt, and so the weight on the tectonic crust is different, and that's the definition of an earthquake. If the tectonic plates are springing up or being pressed down, that's when earthquakes and volcanic eruptions happen. So every scientist I spoke to who had studied this thinks that we're in for a wild time.
