The year 536 AD sounds amazing for snow lovers. I prefer a huge eruption over a quake.
Climate historians believe that this major cooling that began in 536AD occurred because of a massive volcanic eruption. This would account for the descriptions of dark skies and the subsequent cooling of the Earth for about 18 months. Temperatures fell by 2.5°C. It even snowed in China during the summer
