Imagine a broad highway. It has edges and fairly predictable curves, but not much else in the way of controls. That’s the climate.
Now imagine you’re driving along this highway. The lack of controls means you can take any number of paths within the existing edges and curves. You’re the weather.
Now someone comes along and, unpredictably, moves the edges and reroutes the curves. That’s climate change.
Most of the time you (the weather) will carry on as you always have. But the more the climate highway gets wider or narrower, bendier or straighter, the more likely you are to crash.
