Milankovitch cycles — Past and future Milankovitch cycles. VSOP allows prediction of past and future orbital parameters with great accuracy. ε is obliquity (axial tilt). e is eccentricity. ϖ is longitude of perihelion. esin(ϖ) is the precession index, which together… … Wikipedia
Phantom time hypothesis — The Phantom time hypothesis is a conspiracy theory developed by Heribert Illig (born 1947 in Vohenstrauß, Germany) in 1991. It proposes that there has been a systematic effort to make it appear that periods of history, specifically that of Europe … Wikipedia
100,000-year problem — The 100,000 year problem is a discrepancy between past temperatures and the amount of incoming solar radiation, or insolation, which grows and shrinks periodically on a 100,000 year (100 ka) timescale.Due to variations in the Earth s orbit, the… … Wikipedia
Ice age — An ice age is a period of long term reduction in the temperature of the Earth s surface and atmosphere, resulting in an expansion of continental ice sheets, polar ice sheets and alpine glaciers. Glaciologically, ice age is often used to mean a… … Wikipedia
climate change — Introduction periodic modification of Earth s climate brought about as a result of changes in the atmosphere as well as interactions between the atmosphere and various other geologic, chemical, biological, and geographic factors within the Earth … Universalium
Climate change — For current and future climatological effects of human influences, see global warming. For the study of past climate change, see paleoclimatology. For temperatures on the longest time scales, see geologic temperature record … Wikipedia
Global cooling — in general can refer to an overall cooling of the Earth. In this article it refers primarily to a conjecture during the 1970s of imminent cooling of the Earth s surface and atmosphere along with a posited commencement of glaciation. This… … Wikipedia
List of climate scientists — Climate scientists study the statistics of the Earth s temperature (top) and precipitation (bottom) for a better understanding of the climate system. This list of climate scientists contains famous or otherwise notable persons who have contribute … Wikipedia
Orbital forcing — is the effect on climate of slow changes in the tilt of the Earth s axis and shape of the orbit (see Milankovitch cycles). These orbital changes change the total amount of sunlight reaching the Earth by up to 25% at mid latitudes (from 400 to 500 … Wikipedia
