In this lesson, we will investigate a combination of several different datasets and models in order to analyze the extent to which global climate is affected by human activity. We will discuss the short and long term consequences of global warming and try to quantify the uncertainties inherent in scientific measurements.

About Lesson 5
Lesson 5 will take us two weeks to complete. The topic here (also worthy of a course in itself) is recent climate change. My plan is to spend week one studying the data and observations related to climate change and then spend the second week thinking about models, theories, predictions, and discourse (scientific and political) based on those data and observations. I chose to break up this lesson in this manner because I think some of the misunderstandings about what is, and is not, known about recent climate change comes from a general public that is not literate when it comes to the task of distinguishing observations from models, and from scientists who use words such as "belief" and "uncertainty" without realizing that the general public interprets those words differently than scientists do.
The topics in lesson 5 are covered in a more rigorous semester-long fashion in Meteo 469, so if climate science interests you, that's a good course to take.
What will we learn in Lesson 5?
By the end of Lesson 5, you should be able to:
- Differentiate between data and models
- Predict short- and long-term consequences of global warming
- Quantify the uncertainties inherent in scientific measurements
- Define feedback mechanisms associated with climate systems
- Define the greenhouse effect and list greenhouse gases
- List causes and consequences of sea level rise
