A mass grave dating back to the 14th century, discovered in London during the 1990″s , was believed to contain victims of the plague, or famine that hit Europe in 1350. Now scientists aren’t so sure. Further investigation has them pondering. Sometime around 1258, a massive volcanic eruption, larger than Krakatoa, estimated to be on a bigger scale than any in 10,000 years, occurred somewhere in Indonesia or South America. The amount of sulphurous gas released into the atmosphere was 8 times that of Krakatoa. It is believed the ensuing choke hold on Earth’s atmosphere may have lowered global temperatures by as much as 4C, it may not sound like much, but the results would have been catastrophic.
