Climate change can also be used more broadly to include changes to the climate that have happened throughout Earth's history. [121] Global warming —used as early as 1975 [ 122 ] —became the more popular term after NASA climate scientist James Hansen used it in his 1988 testimony in the U.S. Senate . [ 123 ]
Azolla event may have ended a long warm period 5.3–2.6: Pliocene climate became cooler and drier, and seasonal, similar to modern climates. 2.5 to present: Quaternary glaciation, with permanent ice on the polar regions, many named stages in different parts of the world
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 ...

Large-scale reconstructions covering part or all of the 1st millennium and 2nd millennium have shown that recent temperatures are exceptional: the Intergovernmental Panel on Climate Change Fourth Assessment Report of 2007 concluded that "Average Northern Hemisphere temperatures during the second half of the 20th century were very likely higher ...
The Younger Dryas (YD, Greenland Stadial GS-1) [2] was a period in Earth's geologic history that occurred circa 12,900 to 11,700 years Before Present (BP). [3] It is primarily known for the sudden or "abrupt" cooling in the Northern Hemisphere, when the North Atlantic Ocean cooled and annual air temperatures decreased by ~3 °C (5.4 °F) over North America, 2–6 °C (3.6–10.8 °F) in Europe ...
"Because of the Inflation Reduction Act, we’ve already saved more than 3.4 million Americans $8.4 million on clean energy upgrades to their homes, and more than 300,000 Americans have saved over ...
