Implications of “peak oil” for atmospheric CO2 and climate

Peaking of global oil production may have a large effect on future atmospheric CO2 amount and climate change, depending upon choices made for subsequent energy sources.

We suggest that, if estimates of oil and gas reserves by the Energy Information Administration are realistic, it is feasible to keep atmospheric CO2 from exceeding approximately 450 ppm, provided that future exploitation of the vast reservoirs of coal and unconventional fossil fuels incorporates carbon capture and sequestration.
