A flurry of nuclear weapons tests carried out amid the Cold War arms race may have had a profound impact on weather patterns across the planet, increasing rainfall thousands of miles away from testing sites, a new study found.
Using historical records from a research facility in Scotland dating back to the peak of the Cold War, a team of scientists compared day-to-day changes in the electric charge flowing through clouds following “the release of artificial radioactivity” – unleashed by nuclear explosions, that is – to determine how the bomb tests affected rainfall. Their findings were published in the Physical Review Letters journal on Wednesday.
