A heated mirror for future climate

Richard B. Alley
  • States the possible effects of rapid carbon dioxide (CO2) release may be clearest from the Paleocene-Eocene Thermal Maximum (PETM) about 55.9 million years ago, when a large, natural CO2 release drove strong warming that caused amplifying feedbacks, dwarfing of large animals, ecosystem disruptions, soil degradation, water-cycle shifts, and other major changes
  • States the climatic changes during the PETM occurred over longer time scales than those of anthropogenic climate change, implying the impacts of the latter may thus be even more severe
