Global warming or body fat?

This year has been odd. It's not the world which has been facing Global warming. Everyone around me has been feeling cold, but I don't feel cold. What's happening with me? I was always the wimp one who would feel cold and would dress in 20 layers all the time, but not this year. Feels strange. I wonder what has changed? Maybe I'm building body fat... it could be. I was always the skinny one at home and when I sent a picture to my parents they said I was fat. Maybe that's it. Who knows...
