CORRECTIONS: @8:30 - the right hand bar of the chart is labelled "2008 years ago". That should just be 2008, the year of the research.

PLEASE NOTE: The smoke in the photo of the cement plant is NOT CO2 (I know everyone knows that, but some smart-ass in the comments section is going to assume I think it is, or that you think it is. Let's humor them)

I didn't have the space in this viedo to show evidence that not all the the 'greening' is due to CO2. A lot of it is due to human activity. See here:

"Our results indicate that land use change is the dominant factor driving the long-term changes in vegetation greenness."
