It’s called the Palaeocene–Eocene Thermal Maximum (PETM): a monumental and mysterious global warming event that scientists have never been able to fully explain. Well over 50 million years ago, this epic climate abnormality produced a massive injection of carbon into the atmosphere. The build-up lasted some 20,000 years, and sent global temperatures soaring by as
