While Americans are preoccupied with the antics of an insane criminal president, the world spins on.
Perennial tensions between nuclear armed India and Pakistan boiled over – and above, two senior glacier experts remind us that as a warming climate causes glaciers to retreat in the Himalayas, water and food pressures will increase in the most densely populated areas of the world.
Jeff Masters in Weather Underground:
As nuclear-armed India and Pakistan engage in military clashes over the disputed Kashmir region, consider that a “limited” nuclear war between them is capable of causing a catastrophic global nuclear winter that could kill two billion people. The inevitable wars and diseases that would break out could kill hundreds of millions more.
A 2008 paper by Brian Toon of the University of Colorado, Alan Robock of Rutgers University, and Rich Turco of UCLA, “Environmental Consequences of Nuclear War”, concluded that a war between India and Pakistan using fifty Hiroshima-sized weapons with 15-kiloton yield on each country, exploded on cities, would immediately kill or injure about forty-five million people. However, the final toll would be global and astronomically higher, according to recent research.
The most recent study of the environmental aftermath of a nuclear conflict, Mills et al. 2014, Multidecadal global cooling and unprecedented ozone loss following a regional nuclear conflict, used an Earth system climate model including atmospheric chemistry, ocean dynamics, and interactive sea ice and land components, to investigate a limited nuclear war where each side detonates fifty 15-kiloton weapons over urban areas—less than half of the existing arsenals of the approximately 140 warheads each that India and Pakistan have. These urban explosions were assumed to start 100 firestorms. Firestorms are self-feeding fires that suck air into themselves and generate immense columns of rising smoke which lofts into the stratosphere, where it spreads globally. The model predicted the smoke would block enough sunlight for the Earth to experience the coldest temperatures since the last ice age, thousands of years ago.
