From ancient times, people suspected that the climate of a region could change over the course of centuries. For example, Theophrastus, a pupil of Ancient Greek philosopher Aristotle in the 4th century BC, told how the draining of marshes had made a particular locality more susceptible to freezing, and speculated that lands became warmer when the clearing of forests exposed them to sunlight.

In northern Peru and central Chile climate change is cited as the driving force in a series of migration patterns from about 15,000 B.C. to approximately 4,500 B.C. Between 11,800 B.C. and 10,500 B.C. evidence suggests seasonal migration from high to low elevation by the natives while conditions permitted a humid environment to persist in both ...
1800–1500: Middle Bronze Age Cold Epoch, a period of unusually cold climate in the North Atlantic region Bond Event 2: Possibly triggering the Late Bronze Age collapse: 900–300: Iron Age Cold Epoch cold in North Atlantic. Perhaps associated with the Homeric Minimum: 250 BC–400 AD: Roman Warm Period
Eunice Newton Foote (July 17, 1819 – September 30, 1888) was an American scientist, inventor, and women's rights campaigner.She was the first scientist to confirm that certain gases warm when exposed to sunlight, and that therefore rising carbon dioxide (CO 2) levels could increase atmospheric temperature and affect climate, a phenomenon now referred to as the greenhouse effect.
2021—IPCC's 6th report states that the science of climate change is irrefutable and that irreversible changes have already occurred. [37] 2021—Japan announced it will release 1.25 million tons of treated wastewater contaminated by the wrecked Fukushima Daiichi Nuclear Power Plant into the Pacific Ocean.
Environmental historians have been criticized for what is called “recentism,” that is examining twentieth-century environmental issues. [15] Works by archeologists and historians focusing on the colonial era in Latin America (1492-1825), which were not called “environmental history” at the time, are a rejoinder to that criticism.
