What we know for sure was that there was a sudden, enormous influx of carbon that has dissolved in the ocean and atmosphere. As atmospheric CO2 content increased, the average global surface temperature rose 5°C to 9°C (9°F to 16°F). This global warming event is called the Paleocene-Eocene Thermal Maximum (PETM) and lasted for 170,000 years. Events triggered […]
