Join the Echo Climate Change Symposium for a panel discussion in which the panelists will share an overview of the impacts of climate change. The panelists will include Glenn Sheehan, Tim Churchill, and Jeff Williams. Join photographer David Arnold as he talks about photographing climate change. Join panelists Richard Glenn, Jim Leavitt, and others to discuss the impact of climate change on Arctic Ecosystems and Populations TI staff educator Sandra Robbins touts the merits of a book that examines how to address student misconceptions in the science classroom. The book is Targeting Students’ Science Misconceptions: Physical Science Concepts Using the Conceptual Change Model by Joseph Stepans, published by the Idea Factory in 2003. We tour the NOAA Atmospheric Research Observatory at the South Pole where scientists are monitoring carbon dioxide levels, CFCs, solar radiation, and the ozone hole. Dr. Marvin Speece, professor of geophysical engineering at Montana Tech and co-Principal Investigator of the Offshore New Harbor Project, discusses how their expedition collects scientific data. From a small rubber boat on a Greenlandic lake, climate researcher Billy D'Andrea introduces some of the equipment scientists use in limnological sampling. (Limnology is the study of freshwater systems, like lakes.) Climate researcher Billy D'Andrea and colleagues explore the remote "back lakes" of Greenland. To understand how Earth’s climate system has changed over time, scientists need to find, develop and use natural recorders of temperature and precipitation. One natural thermometer comes in the form of alkenones: trans-fats produced by certain algae. Alaska's coastal range is covered in literally thousands of thaw lakes. Ken Hinkel, Yongwei Sheng and John Lenters are embarking on a project to reveal the subtle energy dynamics that take place within these lake systems.
