Mean Atmospheric CO2

The carbon dioxide in the Earth's atmosphere has been rising steadily since the industrial revolution. Quantifying the impact of rising concentrations requires data. Most data is typically presented graphically, but analysis requires the numbers.

In this 3 minute video, we show how Dagra was used to extract the mean atmospheric carbon dioxide level from the Wikipedia article on Carbon dioxide in the Earth's atmosphere.
