This video describes the basic science of climate change. How do we know about climate in the past? What are humans interfering with? How can we make predictions about what will happen in the future?

Climate change is the planetary issue of our time and it’s the issue where human beings finally realized that they were affecting everything. This video looks at some of the ways scientists are able to understand the state of our climate…from thousands of years in the past to the present and projecting into the future.
- Using proxies
- Using models
- Finding relationships and trends
- Understanding how science makes progress: replication of results
- Applying scientific knowledge
- Climate Modeling – NASA Goddard has developed an educational version of their climate models that students can use to explore climate variables. See: http://edgcm.columbia.edu (DS – using models)
- Data Interpretation – Put together a portfolio of climate figures (IPCC forcings, sea level, global temperature, ice record, fire frequency, etc.). Have students work in groups to understand the data being described and then present that data to the class. If there’s time, discuss how some of these graphs can be misinterpreted to support a climate denier’s viewpoint. (DS – using proxies, using models, doing statistical analysis, interpreting graphs; KS – communicating science)
