Quizplus · Accepted Answer

The PETM was characterized by a sudden increase in atmospheric carbon, as evidenced by carbon isotope signatures in sedimentary rocks. This increase in carbon likely led to a significant warming of the planet. Other factors, such as reduced surface albedo and volcanic activity, may have contributed to the warming, but the sudden increase in carbon is considered the primary driver.
