"220 times as much CO2 in the Earth's atmosphere as methane", but how did it get there, how fast is it increasing and why?

The increase in CO2 got there from fossil fuel use and changes in land use.
How fast is it changing? See graph below. The Earth was going through cycles of ice ages until the beginning of the industrial age, and then the CO2 levels just took off.
