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 ]
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.

Historical climatology is the study of historical changes in climate and their effect on civilization from the emergence of homininis to the present day. It is concerned with the reconstruction of weather and climate and their effect on historical societies, including a culturally influenced history of science and perception. [1]
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 ...
Diagram showing climatic zone corresponding with those suggested by Aristotle. The climes (singular clime; also clima, plural climata, from Greek κλίμα klima, plural κλίματα klimata, meaning "inclination" or "slope" [1]) in classical Greco-Roman geography and astronomy were the divisions of the inhabited portion of the spherical Earth by geographic latitude.
Reconstructions of global temperature of the past 2000 years, using composite of different proxy methods. In the study of past climates ("paleoclimatology"), climate proxies are preserved physical characteristics of the past that stand in for direct meteorological measurements [1] and enable scientists to reconstruct the climatic conditions over a longer fraction of the Earth's history.
This data will also be used to build a global dataset of historical weather reconstructions based on a grid of two degrees of latitude by two of longitude at six hourly intervals, entitled the 20th Century Reanalysis, or 20CR. Version one of 20CR, covering 1891 to 2008, was released in Autumn 2009.
