What is PETM?

The Paleocene-Eocene Thermal Maximum (PETM) was a significant global warming event that occurred around 56 million years ago. During the PETM, the earth's temperature rose by 5-8 degrees Celsius over a few thousand years, leading to significant changes in the environment and extinction of several species. The primary cause of the PETM is believed to be the release of large amounts of carbon dioxide and methane into the atmosphere, likely from volcanic activity or the melting of frozen methane hydrates. PETM serves as a critical geological event for understanding the impacts of rapid climate change on the earth's ecosystems and provides valuable insight into the potential consequences of modern-day climate change.
