In the history of artificial intelligence, an AI winter is a period of reduced funding and interest in artificial intelligence research. [1] The field has experienced several hype cycles , followed by disappointment and criticism, followed by funding cuts, followed by renewed interest years or even decades later.
An impact winter is a hypothesized period of prolonged cold weather due to the impact of a large asteroid or comet on the Earth's surface. If an asteroid were to strike land or a shallow body of water, it would eject an enormous amount of dust, ash, and other material into the atmosphere , blocking the radiation from the Sun .

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.
The conversion of sulfur dioxide to sulfuric acid, which condenses rapidly in the stratosphere to form fine sulfate aerosols. A volcanic winter is a reduction in global temperatures caused by droplets of sulfuric acid obscuring the Sun and raising Earth's albedo (increasing the reflection of solar radiation) after a large, sulfur-rich, particularly explosive volcanic eruption.
Winter sowing is a method of starting seeds outdoors in winter. This is generally done with seeds that require a period of cold stratification. The method takes ...
