Global-scale forcing mechanisms today include unprecedented rates and magnitudes of human population growth with attendant resource consumption, habitat transformation and fragmentation, energy production and consumption, and climate change, says the study.
Human activity drives todays global-scale forcing mechanisms more than ever before. As a result, the rate of climate change we are seeing now exceeds the rate that occurred during the extreme planetary state change that tipped Earth from being in a glacial to an interglacial state 12,000 years ago. You have to go back to the end of the cataclysmic falling star, which ended the age of dinosaurs, to find a previous precedent."
