Eyes on the Earth Track Earth's vital signs from space and fly along with NASA's Earth-observing satellites in an interactive 3D visualization. Earth’s Timeline and History. Berger, F. Mesinger, and D. Šijači, Eds. > >| All records span the last 150,000 years, but the dataset degrades to approximately 10 records by 800,000 years ago. Committee on Surface Temperature Reconstructions for the Last 2,000 Years, Temperature record of the past 1000 years, "Global Temperature Report: January 2019",, "Proxy-based reconstructions of hemispheric and global surface temperature variations over the past two millennia", "A Pliocene-Pleistocene stack of 57 globally distributed benthic d, NASA's Goddard Institute for Space Studies, Surface Temperature Reconstructions for the last 2,000 Years, Intergovernmental Panel on Climate Change (IPCC), United Nations Framework Convention on Climate Change, Reducing emissions from deforestation and forest degradation,, History of climate variability and change, Wikipedia indefinitely semi-protected pages, Articles with dead external links from December 2019, Articles with permanently dead external links, Creative Commons Attribution-ShareAlike License, This page was last edited on 17 October 2020, at 20:53. For records of extreme weather events, see, Tree rings and ice cores (from 1,000-2,000 years before present), Paleoclimate (from 12,000 years before present), Ice cores (from 800,000 years before present), National Research Council (U.S.). Civilization developed during the Holocene, the interglacial period of the past 10,000 years during which global temperature and sea level have been unusually stable. found trends of +0.19  degrees Celsius per decade when applied to the RSS dataset. [3], In 2004 Fu et al. The Holocene Climatic Optimum was generally warmer than the 20th century, but numerous regional variations have been noted since the start of the Younger Dryas. Figure 1 shows two prior interglacial periods that were warmer than the Holocene: the Eemian (about 130,000 years ago) and the Holsteinian (about 400,000 years ago). The history of Earth's temperature - BBC Environment - Duration: 3:53. A climate forcing is an imposed change of Earth's energy balance, as may be caused, for example, by a change of the sun's brightness or a human-made change of atmospheric CO 2. Detailed information exists since 1850, when methodical thermometer-based records began. This means you're free to copy and share these comics (but not to sell them). Since December 1978, microwave sounding units on satellites have produced data which can be used to infer temperatures in the troposphere. Earth was completely unrecognizable. 2016 was the third year in a row that global average surface temperature set a new record, and the fifth time the record has been broken since the start of the twenty-first century. Several groups have analyzed the satellite data to calculate temperature trends in the troposphere. 20,000 years ago - 2,000 years ago. An ice age is a period of colder global temperatures that features recurring glacial expansion across the Earth’s surface. various authors for relative accuracy as of 2020 . More details. This animation shows the yearly history of Earth's temperature since the modern record began in 1880. which reveal how the climate system is responding to rapid human-made changes of atmospheric composition, especially atmospheric carbon dioxide (CO2). [2] For the lower troposphere, UAH found a global average trend between 1978 and 2019 of 0.130 degrees Celsius per decade. Note: This comic is a timeline on how the temperature has changed from 20,000 BCE (Before Common Era) to the present day (2016), with three predictions for the rest of the 21st century depending on what actions are taken (or not taken) to stop CO₂ emission. Recent evidence suggests that a sudden and short-lived climatic shift between 2200 and 2100 BCE occurred in the region between Tibet and Iceland, with some evidence suggesting a global change.
