Hi, there! :)
Answer: False.
The Earth has experienced periods of warming and cooling throughout its history, and the current rate of warming is faster than at any other time in the past 2,000 years. However, the Earth has experienced periods of rapid warming in the distant past, such as during the Paleocene-Eocene Thermal Maximum about 55 million years ago. Nonetheless, the current rate of warming is unprecedented in human history and is largely attributed to human activities.
Hope that helps! Good luck! ^_^
