I have a giant folder of climate-related graphics. Here is the function you get when you plot CO2 concentration against sea level during the last ~35 million years

Earth's history shows us that the last time the atmosphere had a CO2 concentration of 400ppm was more than 2.5 million years ago. Sequence stratigraphic backstripping shows that sea level was approximately 22 m above present-day levels, implying that this is the threshold for the collapse of marine-based Antarctic Ice sheets.
