Was browsing reddit when I saw a thread about the effect on Earth if the original supercontinent had never broken up. I know WoB has confirmed that the Stormlight Archive is set on a supercontinent, and one post stuck out to me.

Apparently it is theorized that regular massive hurricanes would be one of the results. Don't know if Brandon knew and planned for that to be the case, but either way it's worked out well for him.
