War-born Climate Change

A nuclear war could have profound effects on crops yields around the world, according to a new study.

A hypothetical war between India and Pakistan would decrease the yield of staple crop around the world, according to a study published in the journal Climate Change.

Researchers from the University of Wisconsin-Madison and Rutgers calculated impact of 50 nuclear weapons used by each of the two countries, and found that the soot from fires started by the bombs would travel to neighboring countries and block the sunlight, smothering fields of crops around the world. The authors were surprised to see such a large effect “from a war with 50 small nuclear weapons per side— much, much less than 1 percent of the current nuclear arsenal,” Alan Robock of Rutgers University said in a press release. Indeed, according to the model, the soot would reduce corn and soy yields as much as 20 to 40 percent, respectively, in places as far away as Indiana and Missouri.

“Hopefully this will never happen,” Mutlu Ozdogan from the University of Wisconsin-Madison said in the press release. “But if it happens, if the prospect is there, these are some of the results that people could expect.”

Has there been similar studies on the wars already going on in the world. For example, the effect of war in middle east on the crops. Doing academic exercise is useful but it can be a great tool if used for practical situations.

Between 1945 and 1988, 174 MEGATONS of atmospheric radioactive poison was spewed into the planet by the U.S. alone. 80% of the megatonnage was exploded over the Marshall Islands.

I've got news for those saying, "I hope this never happens" because it HAS ALREADY HAPPENED. We are now downstream of all those radionuclides out there that will affect all living things for thousands of years. It is a total obfuscation to talk about crop loss from dust clouds when the radionuclides in the fallout do so much more long term damage to EVERYTHING that is alive.

"For the sake of comparison, it may be noted that from 1945 to 1988, the U.S. conducted a total of 930 known nuclear tests with a combined yield estimated to be 174 megatons. Approximately 137 megatons of that total was detonated in the atmosphere. In other words, while the number of tests conducted in the Marshall Islands represents only about 14% of all U.S. tests, the yield of the tests in the Marshalls comprised nearly 80% of the atmospheric total detonated by the U.S."Source:www.nuclearclaimstribun... is the way the U.S. looked like as to Cesium 137 deposition BEFORE Fukushima. I shudder to think what it looks like now.ieer.org/wp/wp-content/upl... is just from the Nevada tests:ieer.org/wp/wp-content/u... Also during this period the Navajo communities near Uranium mines were being afflicted with radiation poisoning from inhaled radioactive dust (NOT just the miners but the familes totally uninvolved with mining as well). This was kept secret from the American public, of course. Documentary here:www.downtheyellowcakeroad...

And then there is Fukushima doing multi-generational damage as well.

Have a nice day.
