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

Climate change can also be used more broadly to include changes to the climate that have happened throughout Earth's history. [32] Global warming—used as early as 1975 [33] —became the more popular term after NASA climate scientist James Hansen used it in his 1988 testimony in the U.S. Senate. [34] Since the 2000s, climate change has ...
Before cameras, history was told through words, paintings, and fading memories. But with their invention, we gained something remarkable—the ability to capture moments exactly as they were. Now ...
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 ]
He also suspected that human activities could influence the radiation balance and Earth's climate, although he focused primarily on land-use changes. In an 1827 paper, Fourier stated, [ 19 ] The establishment and progress of human societies, the action of natural forces, can notably change, and in vast regions, the state of the surface, the ...
Anthropogenic climate change is caused by human activity, as opposed to changes in climate that may have resulted as part of Earth's natural processes. [3] Global warming became the dominant popular term in 1988, but within scientific journals global warming refers to surface temperature increases while climate change includes global warming ...
The Sub-Atlantic period began about 225 BC (estimated on the basis of radiocarbon dating) and has been characterized by increased rainfall, cooler and more humid climates, and the dominance of beech forests. The fauna of the Sub-Atlantic is essentially modern although severely depleted by human activities.
