During the reign of Augustus the climate became warmer and the aridity in North Africa persisted. [10] The biotopes of Heterogaster urticae, which in Roman times occurred farther north than in the 1950s, suggest that in the early Empire mean July temperatures were at least 1 °C above those of the mid-20th-century.

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 ...
The phrases renovatio Romanorum ("renewal of the Romans") and renovatio urbis Romae ("renewal of the city of Rome") had been used already during Antiquity. [3] The word renovatio ("renewal") and its relatives, restitutio ("restitution") and reparatio ("restoration"), appeared on some Roman coins from the reign of Hadrian onward, usually signifying the restoration of peace after a rebellion.

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]
Sunshine duration is about 2,500-2,700 hours per year, from 147 – average 4.7 hours of sunshine per day in December to 338 – average 10.9 hours of sunshine per day in July. [8]
