Importance of this Unit to the Course
To provide a basis for evaluating the quality of climate models described in previous units and to understand the impact of changes in precipitation and temperature to be discussed in block 3, we need very complete and accurate long term measurements of the temperature and precipitation across the Earth. This unit provides information relating to the amount and quality of these measurements.
Preparation for Discussion (You must complete this section before class.)
Discussion (online / face-to-face)
(See your portfolio for due dates and times)
A major component of the course is participation in the online dialog. The following types of comments are required:
If temperatures used in climate studies are measured only to the nearest whole degree, why can we have any confidence in statements about changes in global temperatures amounting to only a few tenths of degrees?
