500 million years of climate change Ice core data for the past 400,000 years, with the present at right. Note length of glacial cycles averages ~100,000 years. Blue curve is temperature, green curve is CO 2, and red curve is windblown glacial dust (loess).
End of the pre-Boreal period of European climate change. Pollen Zone IV Pre-boreal, associated with juniper, willow, birch pollen deposits. Neolithic era begins in Ancient Near East. Evidence of the earliest settlement in Jericho; In Antarctica, long-term melting of the Antarctic ice sheets is commencing.
— 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.
1816 is known as the Year Without a Summer because of severe climate abnormalities that caused average global temperatures to decrease by 0.4–0.7 °C (0.7–1 °F). [1] Summer temperatures in Europe were the coldest of any on record between 1766 and 2000, [2] resulting in crop failures and major food shortages across the Northern Hemisphere. [3]
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.

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 ...
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.
The timeline of meteorology contains events of scientific and technological advancements in the area of atmospheric sciences.The most notable advancements in observational meteorology, weather forecasting, climatology, atmospheric chemistry, and atmospheric physics are listed chronologically.
