Atmospheric carbon levels visual

This video, produced by the National Oceanic and Atmospheric Administration shows how atmospheric carbon levels have changed over time, visualised in a startling and not previously seen manner.

Firstly it starts by looking at the rapid rise in carbon levels over the past 100 years. This is shocking enough, but when it's put in the context of the past 800,000 years (with it's multiple associated ice ages), this puts beyond any doubt that carbon levels now are at unprecedented levels, and that the rise has been so rapid that it cannot have been caused by anything other than human intervention.

These are first rate graphics that provide a startling wake up call.
