"Even a regional nuclear war could spark "unprecedented" global cooling and reduce rainfall for years, according to U.S. government computer models.
Widespread famine and disease would likely follow, experts speculate."
On today's episode I talked a little about "Black Swan" events. I would say that this very nearly qualifies. And the scary thing is considering all the countries in the world that possess nuclear arsenals, including some unstable ones (Pakistan, I'm looking at you!) the likelihood of something like this taking place is higher than any of us want to admit. So, obviously it's the sort of thing that you try to anticipate what the aftereffects would be and plan accordingly. In simple terms, that means prepping for prolonged periods of cooling as well as ways of mitigating "famine and disease" (Obviously your ability to grow your own food would be impacted by the changes in weather pattern, so learning how to grow things under difficult conditions could be very important).
