Heating and Warming: Sensitivity of Earth’s Climate to Atmospheric CO2
All web seminar participants use online tools that allow them to mark-up presenter's slides or share desktop applications in addition to engaging in chat with others online and answering poll questions

This Web Seminar took place on September 24, 2012 from 6:30 p.m. to 8:00 p.m. Eastern Time. The presenters were Scott Denning, Professor of Atmospheric Science at Colorado State University, and Randy Russell, Lead Web and Interactive Multimedia Developer for Spark. During the program, Dr. Denning and Dr. Russell described Earth's “energy budget” and explained how changes in the amount of carbon dioxide in our planet's atmosphere can alter global temperatures.

The PowerPoint, related resources from the NSTA Learning Center, and web links from the presentation are now contained in the above resource collection. Clicking on the collection link will place it in your Learning Center, My Library, neatly organized under the My Resource Collections tab.


This was the second web seminar in a series examining the use of models (both conceptual models and computer models) for teaching about the science of climate and global change. During this program, Dr. Denning talked about the concept of heat budgets, explaining how the amount of solar energy absorbed by Earth equals the amount of thermal energy emitted by Earth, creating planetary heat balance. He also discussed the impact of this process on Earth’s current and future climate. Dr. Russell introduced participants to a number of resources, including classroom activities and web-based interactives, that give students a chance to explore albedo, infrared light, the greenhouse effect, and other climate-related concepts.


Seminar participants received one of the NSTA SciGuides. A certificate of attendance was deposited into participants' My PD Record and Certificates area in the NSTA Learning Center for completing the evaluation form at the end of the program.


Here are some comments provided by the participants at the end of the Web Seminar:

  • “The combination of concept presentation and then augmenting with the web tour interactives helps me incorporate this into my curriculum for my students.”
  • “Very well presented; nice balance of technical and pedagogical information.”
  • “Clear explanations of complex topics. Mathematical, verbal, and graphic representations of information to allow us to use the materials with different kinds of learners.”
  • “I am anxiously waiting for sessions three and four in this series.”

Thanks to the participants and the presenter for the learning opportunity, the interactions, and a job well done!
