Glaciers are storehouses of precipitation that fell long ago and are an important record of past shifts in climate. (From the Ancient Glacial Ice section of the Website)
2. Before beginning, discuss persuasive essays. What is the objective of a persuasive essay? What is the difference between a properly researched persuasive essay and an opinion piece? How does a researcher use citation to support a premise? What are some basic techniques of persuasion?
