How would a nuclear war affect global warming?

A small regional nuclear war could have an impact on global warming – but the results are still quite grim.

NASA computer models have looked at the impact of 100 Hiroshima-sized bombs as powerful as 15,000 tons of TNT, traded between two developing nuclear powers such as India and Pakistan.

The researchers found that the fires left behind would send five million metric tons of black carbon into the lowest altitude layer of the atmosphere. The soot would absorb solar heat and rise so high that it could not come down to the ground.

The results could actually be global cooling, according to NASA climate models.

NASA physicist Luke Oman at a meeting of the American Association for the Advancement of Science said: “The effects would be [lead] to unprecedented climate change,” before suggesting that two to three years later, the global average temperature would drop by at least 2.25 degrees F and 5.4 to 7.2 degrees F in the tropics, Europe, in Asia and Alaska.

That wouldn’t be a good thing, though.

“Our results suggest that agriculture could be severely affected, especially in areas susceptible to late spring and early autumn frosts,” Oman said, comparing the crop failures and potential famines to those that followed. the volcanic eruption of Mount Tambora in 1815 in Indonesia.

In other nuclear-related news, the US Department of Homeland Security offered some helpful advice in the unlikely event of an apocalyptic nuclear explosion: Don’t use hair conditioner.

They suggested skipping the hair product to avoid significant radiation exposure. However, the use of shampoo is a critical step in the decontamination process, as it eliminates nuclear fallout.

The bizarre and fascinating reason is that the substance can cause radioactive material to adhere to your hair.

Perry Romanowski, a cosmetic chemist, previously explained to NPR: “Unlike shampoo, conditioners are meant to stay on your hair.”

“Skin lotions or moisturizing lotions or colored cosmetics that contain oils – these get on your skin and can attract dust or radiation particles from the air. So that would be a concern,” a- he added.
