Student: Do you have any advice on how I should cover the story?

Advisor: Well, Max will want to talk to you but I am sure he will tell you to find out things like why the physics department’s worried about enrollment?Has the number of students been getting smaller in recent years? By how much? What kinds of plans are they considering to address this problem?

Ok, a lot of people think of earth’s orbit around the sun as being perfectly circular, as smooth and as regular as, say, the way that hands move on a well-made watch, but it just doesn’t work that way. You are probably aware that the earth’s orbit around the sun, it is not shaped like a perfect circle. It is more of an oval, it is elliptical. But the shape of this orbit isn’t consistent; it varies over time, over a period of about a thousand years. Sometimes it is a little more circular, sometimes it is more elliptical. And when earth’s orbit is more elliptical, earth is actually closer to the sun during part of the year. Which makes earth, and in particular, the northern hemisphere, warmer. And why is that important? Well, because most of the planet’s glaciers are in the northern hemisphere, and if it gets too warm, then glaciers will stop forming. And we’ve already talked about how that affects earth’s overall temperature
