Christopher Nolan's biopic of J. Robert Oppenheimer has reignited concerns about the devastating power of nuclear weapons, especially with an estimated 12,512 warheads in existence today.

The consequences of even a fraction of these bombs detonating would be catastrophic, causing immediate death to millions through blast waves and fires. The long-term effects of radiation-induced cancers and genetic damage would haunt future generations.

Scientists have been studying the potential aftermath of a nuclear war for over four decades using advanced computer simulations. In 1982, atmospheric scientists Paul Crutzen and John Birks introduced the idea of a nuclear winter, a global smoke cloud that would block sunlight, leading to a decade of freezing temperatures, famine, and mass starvation.

Modern climate models suggest that the effects may have been underestimated, indicating a "nuclear little ice age" lasting thousands of years after a large-scale nuclear exchange between major powers.

 The conflict in Ukraine has brought back fears of a limited nuclear use, and the urgency to study and raise awareness about the consequences of nuclear weapons has become even more critical.

The world must continue to work towards eliminating these weapons to prevent the potential horror of a nuclear ice age that could devastate life on Earth for millennia.
