In science and history, consilience (also convergence of evidence or concordance of evidence) is the principle that evidence from independent, unrelated sources can "converge" on strong conclusions. That is, when multiple sources of evidence are in agreement, the conclusion can be very strong even when none of the individual sources of evidence ...
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
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]
Consilience: The Unity of Knowledge is a 1998 book by the biologist E. O. Wilson, in which the author discusses methods that have been used to unite the sciences and might in the future unite them with the humanities.
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.
For the climate system, the term refers to a critical threshold at which global or regional climate changes from one stable state to another stable state.". [ 15 ] In ecosystems and in social systems, a tipping point can trigger a regime shift , a major systems reorganisation into a new stable state. [ 16 ]
He explains one of the ways this connection is exhibited by stating, “Where the land is rich, soft, and well watered, and the waters are near the surface so that they become hot in the summer and cold in the winter, and where the climate is nice, there the men are flabby and jointless, bloated and lazy and mostly cowards.” [7] He notes the ...
The Carboniferous extends from about 358.9 ± 0.4 to about 298.9 ± 0.15 Ma. [10] A global drop in sea level at the end of the Devonian reversed early in the Carboniferous; this created the widespread epicontinental seas and carbonate deposition of the Mississippian. There was also a drop in south polar temperatures; southern Gondwana was ...
