WASHINGTON — A nuclear conflict involving as few as 100 weapons could produce long-term damage to the ozone layer, enabling higher than “extreme” levels of ultraviolet radiation to reach the Earth’s surface, new research indicates (see GSN, March 16, 2010).

(Feb. 24) – A 1971 French nuclear test at Mururoa Atoll. The ozone layer could sustain lasting harm from a nuclear exchange involving as few as 100 weapons, allowing increased levels of ultraviolet radiation to reach the Earth’s surface, according to new research (Getty Images).

Increased levels of UV radiation from the sun could persist for years, possibly with a drastic impact on humans and the environment, even thousands of miles from the area of the nuclear conflict.

“A regional nuclear exchange of 100 15-kiloton weapons … would produce unprecedented low-ozone columns over populated areas in conjunction with the coldest surface temperatures experienced in the last 1,000 years, and would likely result in a global nuclear famine,” according to a presentation delivered on Friday at a major science conference in Washington.

Today, there are five recognized nuclear powers — China, France, Russia, the United Kingdom and the United States. India, Israel and Pakistan are all known or widely assumed to hold nuclear weapons, while North Korea has a Read more…

Get ready for a ‘global Katrina’: Biggest ever solar storm could cause power cuts which last for MONTHS

  • Earth is overdue a solar storm as the sun enters its most active period.

The world is overdue a ferocious ‘space storm’ that could knock out communications satellites, ground aircraft and trigger blackouts – causing hundreds of billions of pounds of damage, scientists say.

Astronomers today warned that mankind is now more vulnerable to a major solar storm than at any time in history – and that the planet should prepare for a global Katrina-style disaster.

A massive eruption of the sun would save waves of radiation and charged particles to Earth, damaging the satellite systems used for synchronizing computers, airline navigation and phone networks.
