I can't believe how "warm" it is for December. It's in the 40's here, high 30's. Where's the snow?! I remember as a kid in October it had snowed before... was like in the 80s this year a few times. I know nothing about global warming but I can believe it's happening. Every year it seems to be warmer around this time of year
