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
Albedo — The albedo of an object is the extent to which it diffusely reflects light from the sun. It is therefore a more specific form of the term reflectivity. Albedo is defined asthe ratio of diffusely reflected to incident electromagnetic radiation. It … Wikipedia
Feedback — For other uses, see Feedback (disambiguation). Feedback describes the situation when output from (or information about the result of) an event or phenomenon in the past will influence an occurrence or occurrences of the same (i.e. same defined)… … Wikipedia
Climate change feedback — See also: Avoiding dangerous climate change, Runaway climate change, and Abrupt climate change Climate change feedback is important in the understanding of global warming because feedback processes may amplify or diminish the effect of each… … Wikipedia
Cloud feedback — is the coupling between cloudiness and surface air temperature in which a change in radiative forcing perturbs the surface air temperature, leading to a change in clouds, which could then amplify or diminish the initial temperature perturbation.… … Wikipedia
sea ice — Ice formed from frozen seawater in polar regions. Most sea ice occurs as pack ice, which drifts across the ocean surface; other types of sea ice include fast ice, which is attached to coasts and sometimes the seafloor or between grounded icebergs … Universalium
Positive feedback — Alarm or panic can spread by positive feedback among a herd of animals to cause a stampede. Positive feedback is energy taken from the output of a system and reapplied to the input, which is phase congruent with the input signal. A system… … Wikipedia
Eis-Albedo-Rückkopplung — ist die Wechselwirkung zwischen Kryosphäre (schnee und eisbedeckter Erdoberfläche) und globalem Klima. Nach den Begriffen der Regelungstechnik handelt es sich um eine „Positive Rückkopplung“, die die wirkende Ursache weiter verstärkt. Systeme mit … Deutsch Wikipedia
Karoo Ice Age — The Karoo Ice Age from 300–400 Ma (million years ago) was the second major period of glaciation of the Phanerozoic Eon. It is named after the glacial tills found in the Karoo region of South Africa where evidence for this ice age was first… … Wikipedia
global warming — an increase in the earth s average atmospheric temperature that causes corresponding changes in climate and that may result from the greenhouse effect. [1975 80] * * * Potential increase in global average surface temperatures resulting from… … Universalium
Global warming — This article is about the change in climate Earth is currently experiencing. For general discussion of how Earth s climate can change, see Climate change … Wikipedia
