3 Credits,
3 lecture periods 0 lab periods

Introduction to Earth’s past and evolving climate including analysis of the causes and consequences of recent climate change.  Also includes impacts on human societies and the physical environment as well as mitigation and adaptation strategies.

  

1. Explain the key factors that account for unprecedented recent changes in Earth’s climate and the impact of those changes on the physical environment and human societies.
2. Evaluate short-and long-term climate change mitigation and adaptation strategies.

1. Demonstrate an understanding of the relevant aspects of climatology, biogeography, water resources, and human-environment interactions
2. Recognize the causes of past and current climate change
3. Give detailed accounts of climate change impacts already observed
4. Evaluate linkages between changes in atmospheric warming and other changes in the biosphere
5. Use data-driven reports of the IPCC to predict future changes and their consequences
6. Evaluate IPCC recommendations and the prospects for regional and international solutions to climate change fostered issues
7. Account for the differential impact of climate change on various populations
8. Analyze specific mitigation and adaptation strategies that can be implemented locally, regionally, and globally
