Claim that the Earth has cooled since Medieval or Roman times is contradicted by available data
Claim:
Peer-reviewed studies, geologic records, and all the studies have shown that we have actually cooled since the Roman Warming Period, and likely since the Medieval Warming Period.

Inaccurate
Data shows the Earth is currently warmer globally than at any time in the past 2,000 years
Claim:
Earth’s mean temperature over the last 2,000 years shows two previous periods when temperatures were warmer than they are now; from 1–200 A.D., an epoch called the Roman Warm Period, and more recently the Medieval Warm Period from 900–1100 A.D.
