A "nuclear summer" is a hypothesized scenario in which, after a nuclear winter caused by aerosols inserted into the atmosphere that would prevent sunlight from reaching lower levels or the surface, [61] has abated, a greenhouse effect then occurs due to carbon dioxide released by combustion and methane released from the decay of the organic ...
The year 1816 is known as the Year Without a Summer because of severe climate abnormalities that caused average global temperatures to decrease by 0.4–0.7 °C (0.7–1 °F). [1] Summer temperatures in Europe were the coldest of any on record between 1766 and 2000, [ 2 ] resulting in crop failures and major food shortages across the Northern ...
It makes dramatic long-lasting climate predictions of the effect a nuclear winter would have on the Earth, an event that is suggested by the authors to follow both a city countervalue strike during a nuclear war, and especially following strikes on oil refineries and fuel depots.
The group was founded by University of Chicago scientists who had helped develop the first nuclear weapons for the Manhattan Project. Nuclear, disease and AI fears factor into 2025 Doomsday Clock ...
A geological event such as massive flood basalt, volcanism, or the eruption of a supervolcano [179] could lead to a so-called volcanic winter, similar to a nuclear winter. Human extinction is a possibility. [180] One such event, the Toba eruption, [181] occurred in Indonesia about 71,500 years ago.
Given that, Ree will be happy to hear The Old Farmer's Almanac's winter weather prediction for 2024-2025, which forecasts "a temperate, uneventful winter—potentially a welcome reprieve from the ...
The winter forecast from the federal government – which covered December, January and February – predicted a warmer-than-average winter for the southern and eastern U.S.
From 1983-1985, in a time period during which the "nuclear winter" hypothesis was notably still in its early "apocalyptic" 1-D computer model phase, more than 300 physical, atmospheric, agricultural and ecological scientists from over 30 countries around the world came together to participate in the Scientific Committee on Problems of the Environment-Environmental Effects of Nuclear War (SCOPE ...
