A wicked cool animation of increasing atmospheric CO2 conc. through time. You can also see when new data sources and monitoring sites come on line and the seasonal pulse in the northern hemisphere. Neat! (if scary). Animation by sphericalcat. Hat tip to John Cook.[youtube=http://www.youtube.com/watch?v=k7jvP7BqVi4&w=560&h=340]
That is very cool John!
