Roman Warm Period

The Roman Warm Period was a period of relatively warm conditions in parts of Europe and the North Atlantic region, roughly spanning 250 BCE to 400 CE. Its timing and extent vary among climate records.

Paleoclimatology: The study of past climates using natural archives and historical evidence. This broader field reconstructs the Roman Warm Period from records that predate modern instruments.
Roman Britain: The territories of Britain under Roman rule from the first through early fifth centuries CE. Evidence from Britain anchors some reconstructions of climate during the period.
Medieval Warm Period: A proposed interval of relatively warm conditions in parts of the world during the medieval centuries. Its later timing invites comparison, while neither period was globally uniform.
Roman agriculture: The cultivation of crops and management of livestock across Roman territories. Temperature and rainfall shaped growing conditions, though effects differed across regions and crops.
Paleoclimate proxy: A measurable feature of a natural archive used to infer past environmental conditions. Proxy records underpin claims about warmth, but each captures different places and seasons.
Central England Temperature: A monthly temperature record for central England extending back to 1659. Its instrumental-era coverage cannot directly verify conditions in Roman Britain.
Little Ice Age: A period of widespread cooling in many regions, especially from the sixteenth to nineteenth centuries. It is a later, colder interval often contrasted with earlier European warmth.
Roman wine: Wine produced and traded within the Roman world. Winegrowing limits offer one kind of evidence for past regional growing conditions.
Tree-ring dating: A dating method that matches tree-ring patterns to establish calendar years. Tree rings can preserve annual evidence of growing conditions during parts of the period.
Greenland ice core: A climate archive formed from layered ice sheets in Greenland. Greenland records provide North Atlantic context but are geographically distant from much of Europe.
