This simple video explaining the carbon cycle from the World Meteorological Organization – WMO.

Science teacher Greg Craven succinctly (and amusingly) explains the central ideas that I am trying to get across with climateexperiment.com, most notably the idea that the science of climate change is uncertain and just like businesses who deal with uncertainty all the time, we should use risk management to decide what course of action to take. In this context the argument for action is undeniable. The great tragedy is that the mainstream media rarely puts climate change in this context.

This is the update version of the video The Most Terrifying Video You Will Ever See that has had over 7 million views. It spawned a website, a book and a further 7 hours of video (broken into chapters).

You can probably see the influence this video has had on this site, so cheers Greg for clarifying these ideas so well (and for all the hard work).
