Can we predict future temperatures?

We often see graphs from various places predicting how the world is going to warm up over the next 100 years. Weather prediction is a complex matter since weather is a complex system and a lot of work has been done to make these predictions. A big part of this work includes the use of super computers that simulate entire climate systems and everything affecting it, including the sea, clouds, air and sun.

Scientists have a fairly good understanding of the physical mechanisms that contribute to the weather, and fairly accurate models to predict how a particular component of this system will react to specific influences. What makes it extremely complex is how all these work together, down to each molecule around the surface of the earth.

Chaos Theory describes that small differences in an initial dynamic system can contribute to serious unpredictability later on. This theory came about during work on weather modeling because this is where the effects of it ma…
