The Roman Warm Period affected Europe and the North Atlantic Ocean. 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 ...
Holocene climatic optimum. The Holocene Climate Optimum (HCO) was a warm period in the first half of the Holocene epoch, that occurred in the interval roughly 9,500 to 5,500 years BP, [1] with a thermal maximum around 8000 years BP. It has also been known by many other names, such as Altithermal, Climatic Optimum, Holocene Megathermal, Holocene ...
The Holocene extinction, otherwise referred to as the sixth mass extinction or Anthropocene extinction, [100] [101] is an ongoing extinction event of species during the present Holocene epoch (with the more recent time sometimes called Anthropocene) as a result of human activity.
Cooler climate causes Carboniferous rainforest collapse. 251.9. Permian–Triassic extinction event. 199.6. Triassic–Jurassic extinction event, causes as yet unclear. 66. Perhaps 30,000 years of volcanic activity form the Deccan Traps in India, or a large meteor impact. 66. Cretaceous–Paleogene boundary and Cretaceous–Paleogene extinction ...
The climate of ancient Rome varied throughout the existence of that civilization. In the first half of the 1st millennium BC, the climate of Italy was more humid and cool than now and the presently arid south saw more precipitation. [ 1 ] The northern regions were situated in the temperate climate zone, while the rest of Italy was in the ...
1926 [ 415 ] Extermination campaign. The Great Plains wolf has been later determined to be continuous morphologically [ 410 ] and genetically [ 416 ] with the still existing Mexican wolf, which would use the name C. l. nubilus if placed in the same subspecies, due to being the older one. Red-moustached fruit dove.
The last time the sea level was higher than today was during the Eemian, about 130,000 years ago. [2] Over a shorter timescale, the low level reached during the LGM rebounded in the early Holocene, between about 14,000 and 6,500 years ago, leading to a 110 m sea level rise. Sea levels have been comparatively stable over the past 6,500 years ...
The Holocene calendar, also known as the Holocene Era or Human Era (HE), is a year numbering system that adds exactly 10,000 years to the currently dominant (AD/BC or CE/BCE) numbering scheme, placing its first year near the beginning of the Holocene geological epoch and the Neolithic Revolution, when humans shifted from a hunter-gatherer lifestyle to agriculture and fixed settlements.
