You can look at some aspects of the theory for anthropocentric climate change for falsifiable statements. The explanation for the rise of carbon dioxide in the atmosphere is that humans burn fossil fuels, such as coal, oil, and natural gas. All of which contain no carbon-13 isotopes because of their isolation underground, whereas the carbon released from living things does contain carbon-13, which is formed from the presence on cosmic rays. If nature, and not humans, are the source of carbon emissions, we would expect to see no decrease, with respect to time, in the proportion of carbon dioxide molecules containing carbon-13 atoms in earths atmosphere.
