Example text

And then there is the mass extinction that most people might have a passing knowledge of, the one that wiped out the dinosaurs. Occurring around 65 million years ago, the Cretaceous-Tertiary event killed off 16 percent of marine families, 47 percent of marine genera and 18 percent of land vertebrate families. The probable reason was a large asteroid impact on the Yucatan Peninsula and beneath the Gulf of Mexico, which threw dust into the air and blocked out the Sun, causing large animals to die over the next few million years due to lack of food.

Prime ministers and presidents around the world profess to aspire to a dream world in which the number of these weapons is reduced (perhaps to zero). In July 2009, US president Barack Obama and Russian president Dmitry Medvedev agreed to drop their deployed nuclear arsenal to between 1,500 and 1,675 by 2016. Robock calculated what might happen if this “mother load” of weapons were detonated against urban targets in the US and Russia. Hundreds of millions of people would be killed, and a whopping 180 million tons of soot would be thrown into the atmosphere.

Because of the recent propensity of the population to move into high-density cities, India and Pakistan could face 12 million and 9 million immediate deaths respectively, while an attack on the UK would cause almost 3 million immediate deaths. In the 100-warhead scenario, more than 5 million tons of sooty black smoke would spew from the resulting firestorms. This would float to the upper atmosphere, become heated by the Sun and end up being carried around the world. 25°C. “This would be colder than the little ice age, the largest climate change in human history,” said Alan Robock, a climatologist at Rutgers University who worked with Turco on the analysis.
