The Roman Warm Period, or Roman Climatic Optimum, was a period of unusually-warm weather in Europe and the North Atlantic that ran from approximately 250 BC to AD 400. [1] Theophrastus (371 – c. 287 BC) wrote that date trees could grow in Greece if they were planted but that they could not set fruit there.
Numerous Roman mosaics from North African sites depict fauna now found only in tropical Africa, [6] although it's unclear whether any climate change contributed to that. Throughout the entire Roman Kingdom and the Republic there was the so-called Subatlantic period, in which the Greek and Etruscan city-states also developed. [7]

As instrumental records only span a tiny part of Earth's history, the reconstruction of ancient climate is important to understand natural variation and the evolution of the current climate. Paleoclimatology uses a variety of proxy methods from Earth and life sciences to obtain data previously preserved within rocks , sediments , boreholes ...
Many agents of deterioration play a role in these conservation issues. Paintings being exposed to light, buildings being worn away by natural forces and water damage due to inappropriate excavation and reconstruction methods, as well as theft and vandalism all play a part in the slow decline of the sites' integrity.
Reconstruction is "returning a place to a known earlier state; distinguished from restoration by the introduction of new material into the fabric." [18] The aim of reconstruction is to "preserve and reveal the aesthetic and historic value of the monument and is based on respect for original material and authentic documents." [19]
But there is some evidence that the decline of the Roman West is linked to climate change. [24] Slash-and-burn agriculture, associated with lower populations than the Roman period, can be at least as responsible for deforestation and soil erosion as Roman agriculture. Coastal marshes can be caused by sea level changes quite as much as soil erosion.
Nova Romans performing a Roman ceremony in Aquincum (Budapest), 2008.. Nova Roma holds its own local and international conventions and regularly participates with its affiliated reenactment groups [31] in such history festivals and public events as the Festival of Ancient Heritage [32] in Svishtov, Bulgaria, the Roman Market Day [33] [34] [35] in Wells, Maine's Harbor Park, and Forum Fulvii in ...
