That's not the "natural" temperatures, it's just the temperatures that we've had for the last few thousand years. The last glacial period, with very cold temperatures, was less than 12,000 years ago.
CO2 levels have been much higher and much lower over the last few billion years. There is no "natural" level for CO2.
