John, unfortunately, as you point out the data from Mauna Loa only goes back to the late fifties. So scientists have to indirectly measure CO2 levels for earlier times from things like glacial ice. So there is some dispute as to how long ago it was that CO2 levels are where they are today. Some say 800,000 years, some say five million, some say 15 million years ago. Regardless, it was long before the industrial revolution. And there is a strong correlation between the rate we've been burning fossil fuels and the rate at which CO2 levels are rising.
Lots of folks have done the calculation of how much the earth's temperature will rise if all known fossil fuel reserves are used up. Most say that will raise the average temperature more than 2 degrees Celsius, which is considered the "tipping point" for catastrophe. You can read more at the link below, but I'll give you the short version: We can burn 565 gigatons of fossil fuels and stay below two degrees Celsius increase. The countries of the world INTEND to burn 2795 gigatons.
