A guy named Leo Murray has made a great animated short with the support of the Royal College of Art. It contains some clever visual executions of complex concepts. The video lives here but you can also view it at the bottom of this post.
This visual is brilliant–it sums up capitalism, more or less. See more examples after the jump.

A Still Body Tends to Rest Unless Acted Upon by External Forces



Positive Feedback Mechanisms
I remember learning that methane and water vapor had a substantially greater effect than CO2.

Albedo effect–light particles popping out of the Sun in an amusing way.

Changes in surface water kill plankton and reduce carbon absorption.

Social Disasters
Defense against flooded nations.

Here, a government bureaucrat and a corporate hog work together to create a monster.

The big picture regarding the modern life metaphor.
