Reading Guide -- Lecture 14 -- Global Change
We will only really get to one topic corresponding to this lecture: The
periodicity of glaciations.
In chapter 19, the first few pges, up to p 551, should be review.
Note figure 19.9: which shows the last glacial cycle.
Look closely at fig B19.1 and related text. We will look in detail at the
Oxygen isotopes in class and see how they are used as a proxy for the amount
of water in the oceans, which in turn is a proxy for the amount of water
in the ice sheets, which in turn says something about past climates. You
should read pp 555-557 in detail, and look at the pictures and diagrams
for the rest of the chapter.
