Belated Happy Perihelion
Calvin’s dad is not a scientist, and the cartoon gets it almost exactly wrong.
He says it’s colder because the earth’s orbit is taking us farther from the sun.
The perihelion was Jan 4th, meaning we were closest to the sun then.
The seasons, of course, are caused by the axial tilt.

It’s amusing how much stuff Calvin’s dad gets wrong. I think Bill Watterson does it on purpose.
