No weather forecaster can tell you for sure when to wear a rain slicker, stock up on canned goods, or evacuate a city that's in a cyclone's path. All forecasters can offer is their best guess at the atmosphere of the future, whispered by the simulated blue marble and wrapped up in uncertainty.

Our long-range predictions - especially those which anticipate extreme-weather events - rely on an assumption that the future will be similar to the past. Lose that, and we lose the tools that have allowed us to prepare for such eventualities.

The weather doesn't respect political or geographic boundaries: we're all living under the same sky. And so weather prediction has been a marvel not only of technology but also of international cooeperation.
