This question is addressed through a series of questions and answers, each providing related introductory information such as how climate change is studied, the history of Earth’s climate, and the effects of climate change on Earth’s geology and... (View More)

In this self-paced tutorial, learners examine data to determine the relative contribution of what we call natural climate cycles and that of human-caused greenhouse gases to contemporary climate change. Changes in the Earth-Sun geometry over time... (View More)

In this problem set, learners will analyze a table of the length of day (hours) and the number of days per year on Earth in past eras. They will calculate future values, plot some of the data and identify the rate of increase. Answer key is... (View More)
