I've been a Flat Earther since birth, but one thing started to puzzle me when I went on long trips.  Whenever I travel hundreds and sometimes even thousands of miles closer to the ice wall in a direction some uninformed people call 'South,' the weather gets warmer.  Shouldn't it get colder the nearer we get to the giant ice wall?  Every so called 'winter,' it gets colder where I live in Washington State.  So  I heard some old codgers claim that it would be warmer 'down South.'  I had my doubts, but I tried it out.  I drove all the way to Baja, Mexico and sure enough it was much warmer.  It was also much closer to the great ice wall.  This completely stupefies me, so I want one of you experts to 'splain it to me.
Thanks in advance.
