Natural and Anthropogenic Climate Impacts as Evidenced in Ice Cores

This Web Seminar took place on May 2, 2012 from 6:30 p.m. to 8:00 p.m. Eastern Time. The presenters were Dr. Joseph McConnell, faculty member at the Desert Research Institute (DRI) in Reno, Nevada, and Ms. Linda Morris, Education Program Manager for the NSF-funded Ice Drilling Program Office.

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.

During this program, Dr. McConnell gave a brief overview of climate change as contributed to by greenhouse gasses. He then discussed ice core samples taken from Antarctica and what they reveal about elements in the atmosphere and how closely this data is paralleled with economic and industrial changes around the world. Seminar participants viewed data showing changes in carbon and lead over the last few thousand years compared with major events in cultural history. Ms. Morris introduced participants to the Climate Expeditions website and shared the ‘Polar Detectives’ activity in which students can view data similar to that shared in this program and do related exercises to increase their knowledge of climate change.

Forty-nine (49) participants were present at the live Web Seminar in addition to the presenter and NSTA staff. Participating educators represented the states of Arizona, California, Florida, Georgia, Illinois, Kansas, Kentucky, Massachusetts, Missouri, New Jersey, New York, North Carolina, Ohio, Pennsylvania, Tennessee, Texas, Washington, and Wisconsin. In addition, four participants joined the presentation from locations outside the United States: Germany, Philippines, and Turkey.

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:

  • “I loved the discussion of current ice core data and the inclusion of the graphs in the PowerPoint! I am going to guide my students through an analysis of the graphs so they can see the actual data with which scientists are using.”
  • “Loved this seminar. Resources page will be helpful in the future.”
  • “Global warming and the poles' receiving excess heat from the middle latitudes are important topics for my students to understand.”
  • “Wonderful content and resources.”

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