Final answer:
The statement is false as we are not in the Pleistocene epoch but are currently in the Holocene, an interglacial period after the last ice age of the Pleistocene ended.
Step-by-step explanation:
The statement is false. We are not in an interglacial interval of the Pleistocene, as the Pleistocene epoch ended about 11,700 years ago. Instead, we are currently in the Holocene epoch, which is indeed an interglacial period characterized by warmer global temperatures that followed the last glacial period. The Pleistocene was marked by several glacial and interglacial cycles, with the last ice age ending around 12,000 years ago, leading to the retreat of massive ice sheets that had covered large parts of the Northern Hemisphere.
The climate changes experienced on Earth during the Pleistocene had significant impacts on biodiversity, landscapes, and human migration paths. For instance, woolly mammoths and other cold-adapted megafauna went extinct about 10,000 years ago due to habitat destruction from changing temperatures, as well as over-hunting by humans.
