We truly are a force to be reckoned with.

The current pace of emission has no corollary in the geological record. Based on best observations, the fastest CO2 increases in the past were during either the PETM extinction event of 55 million years ago or the Permian Extinction, or Great Dying, of 250 million years ago. During these periods, rapid rates of CO2 increase were observed at about .35 parts per million each year. The current pace is now six or seven times that seen during these dangerous geological epochs and expected rates of CO2 increase during this century could exceed 20 times that seen in the record.
