Notes on verification
Claim matches Wikipedia's 'Climate of ancient Rome' article and an academic-style encyclopedia entry, suggesting basis in scholarship (e.g., H.H. Lamb, archaeological sea-level proxies). However, most corroborating sources are mirrors/derivatives of the same original text rather than independent verification. A 2024 peer-reviewed paleoclimate study offers partial, generalized support but doesn't precisely confirm the 'cooler and more humid than today' framing for this specific period.
