As a kid I loved looking at those old tapestries in the museum
   (probably new york city?) and wondering, "Wait, foggy, cold
   England? HOW!?" I asked a teacher. They blamed the Industrial
   Revolution and all the coal. Seemed too simple to me. Maybe she
   was partly right but it still didn't seem like the whole story,
   I thought. When I learned about the medieval warming period as
   an adult I was like, YES!
