Why is January colder than December?

The shortest day of the year falls on December. So why isn't December the coldest month of the year? In short, because there's so much water on Earth. (Slate) Huh?

First, consider this. Water is really, really good at storing heat. In fact, it holds five-times more heat (per gram) than rock.

And since the 75 percent of the Earth's surface is water, the heat built up before December keeps the planet warm until January, when the stored up heat is spent and it gets really cold.

I started pound360 to channel my obsession with vitamins, running and the five senses. Eventually, I got bored focusing on all that stuff, so I came back from a one month hiatus in May of 2007 (one year after launching Pound360) and broadened my mumblings here to include all science.
