Regional Nuclear War Would Still Wreak Global Climate Havoc, Says Study

  • This is the first study to include interactive effects of atmospheric physics, ozone chemistry, deep-ocean and sea ice response, and land vegetation all in one earth system model.

  • “(We were) expecting to confirm earlier studies that there would be about a decade of cooler temperatures following such an exchange,” said Mills.

  • Instead, the team found that cooling would last longer than 25 years.

  • Large amounts of ultraviolet radiation would destroy both land- and sea-based ecosystems, as well as agricultural food crops.

Regional Nuclear War Would Still Wreak Global Climate Havoc, Says Study

With Ukrainian tensions mounting, the notion that such regional conflicts could morph into something nuclear is now dogging Western leaders in a way not seen in a generation.

But even a limited regional nuclear conflict would have catastrophic global impact, as detailed in new atmospheric and climate models in a forthcoming paper in the journal Earth’s Future.

A follow-on increase in summertime ultraviolet (UV) surface radiation of as much as 80 percent would be “off the charts” says Michael Mills, an atmospheric scientist at NCAR (the National Center for Atmospheric Research) in Boulder, Colorado, and the study’s lead author.

... large amounts of ultraviolet radiation would destroy both land- and sea-based ecosystems, as well as agricultural food crops, potentially leading to global nuclear famine.

Mills says this is the first study to include interactive effects of atmospheric physics, ozone chemistry, deep-ocean and sea ice response, and land vegetation all in one earth system model.

The team ran seven models using NASA’s Pleiades Supercomputer at the space agency’s Ames Research Center in Silicon Valley.

“(We were) expecting to confirm earlier studies that there would be about a decade of cooler temperatures following such an exchange,” said Mills.

But, instead, he says, the team found that cooling would last longer than 25 years; causing growing seasons worldwide to be reduced by as much as 40 days.
