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
Climate change has been linked to human migration from as early as the end of the Pleistocene to the early twenty-first century. [ 10 ] [ 11 ] The effect of climate on available resources and living conditions such as food, water, and temperature drove the movement of populations and determined the ability for groups to begin a system of ...
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 ...
— Intergovernmental Panel on Climate Change (IPCC) was established by two United Nations organizations, the World Meteorological Organization (WMO) and the United Nations Environment Programme (UNEP) to assess the "risk of human-induced climate change". — Student Environmental Action Coalition founded.
Geochemical Climate Proxy: Ratio of Oxygen-18 to Oxygen-16 in calcite from deep sea sediment, and coral cores More Oxygen-18 = colder climatic periods Mass Spectrometer: ca 542,000,000 yrs BP Beryllium-10 Analysis Geochemical Climate Proxy: Ratio of Beryllium-10 to daughter isotopes in dust from ice cores
2020 – The COVID-19 pandemic, partly due to lockdowns, temporarily drastically reduces the use of surface (including public) and air transport technologies. Cycling is an exception to this and increased during the pandemic, along with bike-sales. [75] [76] 2024: A comprehensive global review of harms from personal car transport is published.
Climate change may be due to internal processes in Earth sphere's and/or following external forcings. [ 41 ] One example of a way this can be applied to study climatology is analyzing how the varying concentrations of CO2 affect the overall climate.
