Stopped reading at climate change.
Well well well....good to see that no one gaf about nukes. Hell I dont because I know my whole area is done...here in Huntsville, Alabama. Maybe y’all might consider simple math; A 1990 US Army study concluded that it would take 10 Megatons total of nuclear weapons to disable the USA’s ability to function as a nation/civilization. Sounds about right. Split up the 350KT city busters and 50KT tactical nukes...10MT should wipe out the US nicely.
The same 1990 study calculated that 5000 MEgatons of destructive nukes exist in the world between all nuke capable countries. If you use Hiroshima as the metric...100,000 dead for each 15KT...5000MT works out to 33 Billion dead. Means theres enough nukes to kill every human being 4X over. Nice thought huh? So, yeah...dont worry about what will happen in a global thermonuclear war...because unimaginable death and suffering is a certainty. Have a nice day.
