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 enrollmentHas 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 earths 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 doesnt work that way. You are probably aware that the earths 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 isnt 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 earths 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 planets glaciers are in the northern hemisphere, and if it gets too warm, then glaciers will stop forming. And weve already talked about how that affects earths overall temperature.
