https://en.wikipedia.org/wiki/Tsar_Bomba https://en.wikipedia.org/wiki/Tsar_Bomba The trend in nuclear weapons has been for lower yields over the last 45 years or so. The reason is that advances in CEP precision due to better guidance systems means than huge yields are no longer necessary in order to ensure destruction of the intended target(s). 'Nuclear winter' is a completely unsupported theory pushed by Carl Sagan and the Union of Confused Scientists. Recall that these same people pushed 'the coming Ice Age' in the 1970s, 'global warming' until even their jiggered data was so obviously wrong that they renamed it 'climate change', and also predicted 'nuclear winter' effects from the burning oilfields during the first Gulf War - which never materialized, of course.
