CO2 from burning fossil fuels and burning plants has a different isotope mix than does CO2 from other sources. We can use this to tell how much of the CO2 in the atmosphere comes from that kind of burning. There aren't enough wildfires or other natural sources to account for more than a small fraction of it.
Hence, we can prove that most of that type CO2 comes from human sources. And that type account for most of the increase since pre-industrial times.
