Nuclear winter' is still a threat to be avoided
His team used a climate model shared by the Intergovernmental Panel on Climate Change to calculate the effects of exploding 100 Hiroshima-sized bombs over major cities - roughly equivalent to an all-out nuclear war between India and Pakistan (Atmospheric Chemistry and Physics, vol 7, p 2003).
They found that the blasts would loft up to 5 million tonnes of black carbon soot into the atmosphere, lowering global temperatures by 1.4 °C. Growing seasons in the middle latitudes would be shortened and in some cases fail entirely. "By explaining the consequences to the world, we hope nothing like this will ever happen," says Robock.
É o retorno de uma velha ideia: uma guerra nuclear mata milhões de pessoas mas isso não interessa nada. O que é realmente importante é a queda de 1.4 °C na temperatura média global.
