I'm not really into global warming, but this December has been amazing. I remember really dark cold Decembers past, where the only redeeming feature beyond making little kids happy, was the awesome "Christmas Crystals" that would form on windows. Really special ice like huuuuge windowshield-smashed monster snowflakes.
Right now in the interior, it's relatively super warm and slushy. Not photogenic nor would it make a nice card image, but it's really pleasant to go out and not freeze to death.
