The time from roughly 15,000 to 5,000 BCE was a time of transition, and swift and extensive environmental change, as the planet was moving from an Ice age, towards an interstadial (warm period). Sea levels rose dramatically (and are continuing to do so ), land that was depressed by glaciers began lifting up again , forests and deserts expanded ...
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.
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
In 1967, Roderick Nash published Wilderness and the American Mind, a work that has become a classic text of early environmental history.In an address to the Organization of American Historians in 1969 (published in 1970) Nash used the expression "environmental history", [4] although 1972 is generally taken as the date when the term was first coined.

Drivers of climate change from 1850–1900 to 2010–2019. Future global warming potential for long lived drivers like carbon dioxide emissions is not represented. The scientific community has been investigating the causes of climate change for decades.
The conservation and restoration of parchment constitutes the care and treatment of parchment materials which have cultural and historical significance. Typically undertaken by professional book and document conservators , this process can include preventive measures which protect against future deterioration as well as specific treatments to ...
Among all of the stations, the average change is a decrease of 0.19% per year. From 1972 to 2013, the U.S. snow cover season became shorter by nearly two weeks, on average, NOAA reports.
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 ...
