Nuclear winter is a severe and prolonged global climatic cooling effect that is hypothesized [1] [2] to occur after widespread firestorms following a large-scale nuclear war. [3] The hypothesis is based on the fact that such fires can inject soot into the stratosphere, where it can block some direct sunlight from reaching the surface of the Earth.
Kalma, Finnish goddess of death and decay, her name meaning "the stench of corpses" [16] Nga ... Itztlacoliuhqui (Aztec mythology), personification of winter-as-death;
Exponential smoothing or exponential moving average (EMA) is a rule of thumb technique for smoothing time series data using the exponential window function.Whereas in the simple moving average the past observations are weighted equally, exponential functions are used to assign exponentially decreasing weights over time.
Without a functioning dynamo, the magnetic field of the Earth will decay in a geologically short time period of roughly 10,000 years. [75] The loss of the magnetosphere will cause an increase in erosion of light elements, particularly hydrogen , from the Earth's outer atmosphere into space, resulting in less favorable conditions for life.
According to Spengler, the Western world was ending and the final season, the "winter" of Faustian Civilization, was being witnessed. In Spengler's depiction, Western Man was a proud but tragic figure because, while he strives and creates, he secretly knows the actual goal will never be reached.
A coyote feeding on elk carrion in Yellowstone National Park's Lamar Valley during winter. Sometimes carrion is used to describe an infected carcass that is diseased and should not be touched. An example of carrion being used to describe dead and rotting bodies in literature may be found in William Shakespeare's play Julius Caesar (III.i): [8]
Marcescence is most obvious in deciduous trees that retain leaves through the winter. Several trees normally have marcescent leaves such as oak ( Quercus ), [ 5 ] beech ( Fagus ) and hornbeam ( Carpinus ), or marcescent stipules as in some but not all species of willows ( Salix ). [ 6 ]
In water ecosystems, relatively little waste collects on the water bed, and so the progress of decomposition in water takes a more important role. Investigating the level of inorganic salts in sea ecosystems shows that unless there is an especially large supply, the quantity increases from winter to spring—but is normally extremely low in summer.
