The Keeling Curve doesn’t demonstrate that climate is changing; it simply provides the evidence that supports the most obvious mechanism to account for the global warming that has also been measured. It does show, in two very concrete ways, that Earth’s atmosphere is finite and can be impacted by the biosphere. Humans account for the increase over time; plants account for the annual periodicity.
