Are Global CO2 Levels Changing?

According to the Mauna Loa observatory, carbon dioxide levels increased by 3 ppm in our atmosphere between 2015–2016. Individuals analyze carbon dioxide data from around the world and then share this with a home group in lesson three of five. From this world perspective of carbon dioxide in the atmosphere, they generate a conclusion regarding global carbon dioxide concentrations and discuss as a class. The lesson finishes by having young scientists determine how these changes affect climate, if at all.
