Thanks for the insult. 30 seconds of research yield the following: The Roman Warm Period was primarily a Northern Hemisphere phenomenon, especially affecting Europe and the North Atlantic.

Other regions experienced mixed or neutral conditions, with some areas warming, others drying, and some even cooling.

Unlike today's anthropogenic global warming, which is globally consistent and measurable in both hemispheres, the Roman Warm Period was regionally variable and driven by natural cycles (solar activity, volcanic activity, ocean circulation).
