Using theories of Paleocene Eocene Thermal Maxima, we got that the true fact about that event compared to the rate at which temperature is currently (2022) increasing is
The Paleocene–Eocene thermal maximum (PETM), alternatively known as "Eocene thermal maximum 1" (ETM1), and formerly known as "Initial Eocene" or "Late Paleocene thermal maximum", was the time period with more than 5–8 °C global average temperature rises across the event.
Hence, the Paleocene Eocene thermal maxima is a climate excursion 50 million years ago during which temperatures spiked 5 degrees as carbon dioxide built up in the atmosphere, the true fact about that event compared to the rate at which temperature is currently (2022) increasing is that-
