     The global temperature declines predicted in the original (1983) nuclear winter scientific paper were 15-20°C; current estimates are 10-15°C. The two values are in good agreement considering the irreducible uncertainties in the calculations. Both temperature declines are much greater than the difference between current global temperatures and those of the last Ice Age. The long-term consequences of global thermonuclear war have been estimated by an international team of 200 scientists, who concluded that through nuclear winter the global civilization and most of the people on Earth— including those far from the northern mid-latitude target zone—would be at risk, mainly from starvation.

     When the salarians discovered them, the krogan were a brutal, primitive species struggling to survive a self-inflicted nuclear winter. The salarians culturally uplifted them, teaching them to use and build modern technology so they could serve as soldiers in the Rachni War.
