Small-scale they call it.
We are back to the future. Nuclear winter deja vu all over again?
And is relevant to the ongoing India-Pakistani crisis.
"How a nuclear war between India and Pakistan could reverse global warming"
"We're at a scary moment internationally as tensions escalate between the nuclear powers of India and Pakistan, and we should all be praying for things to calm down. In addition to the horrible death toll and humanitarian crisis that would follow, according to scientists, a small-scale nuclear war could actually reverse global warming and actually cause devastating global cooling."
This is similar to the Nuclear Winter hypothesis as was the rage over thirty years ago now.
This particular You Tube video describes the exact scenario of a nuclear exchange between India and Pakistan! Detonation of hundreds of atomic warheads [a nuclear exchange between Pakistan and India] of the Hiroshima size [twenty kilotons] within the time span of a few hours to several days at the most. Cooling on a planetary scale with world-wide devastation as a result!! Not even counting radioactivity.
AS I RECALL IT WAS SUGGESTED THAT THE MORE OR LESS SIMULTANEOUS DETONATION OF A THOUSAND HIROSHIMA-SIZED ATOMIC WEAPONS WOULD CAUSE IRREPARABLE HARM ON A GLOBAL-SCALE!
India and Pakistan between them have less than half that number of a thousand nuclear warheads? So we are good to go then?
