The climate scientist Gavin Schmidt, of Columbia University’s Earth Institute, gives a TED talk about complexity in climate models. Complexity arises due to the fact that a climate model must be able to integrate micro climate events into an accurate macro climate model. The climate model must be able to track how events at different magnitudes of scale, whether that be at the atomic level or the global level, interact with one another to create an accurate portrayal of the operations of the Earth’s climate.
Climate scientists models though need to do more though. They also must produce accurate and more informative predictions about how changes to climate variables effects the Earth’s climate. Increasingly, our models are able to incorporate more phenomena at differing scales of magnitudes. Making our models more accurate.
Schmidt concludes that understanding the climate is one thing. It is how we act in response to the data that is of grave importance.
