This is correct. The scientific data are quite solid. It is based on direct measurements of the content in natural sources such as deep ice cores and ocean bottom sediments that can be sampled and tracked across time as well to make a correlation, so the data are accurate and robust to show the long-term trends here. This indeed is a natural cycle.
