Unit: Geoengineering Last Updated on 2012-05-06 00:00:00 SUMMARY There is much unknown about the ramifications of large-scale deployment of geoengineering technologies.  Are they merely short-term fixes?  What are the long-term implications of cloud seeding, etc?  After a discussion and analysis of David Keith’s Ted Talk, students engage in an activity to investigate the pros and cons of existing geoengineering technologies. GOALS In this lesson, students will: Identify the potential pros of existing geoengineering technologies Understand the possible implications of the use geoengineering for climate change mitigation ACTIVITY DESCRIPTION AND TEACHING MATERIALS See lesson plan >> Geoengineering Lesson plan for geoengineering class.

Shrinking Atmospheric Layer Linked to fluctuations in Solar Radiation Last Updated on 2010-08-31 00:00:00 Introduction A shrinking Atmospheric Layer Linked to Levels of Solar Radiation may be driven by large changes in the sun's energy output, and may in turn drive unexpectedly dramatic fluctuations in Earth's outer atmosphere. Results of a study published recently link a recent observed shrinking of a high atmospheric layer with a sharp drop in the sun's ultraviolet radiation levels; the shrinking is presumed to be temporary. The research, led by scientists at the National Center for Atmospheric Research (NCAR) in Boulder, Colorado and the University of Colorado at Boulder (CU), indicates that the sun's magnetic cycle, which produces differing numbers of sunspots over an approximately 11-year cycle, may vary more than previously thought. The results, published this week in the American Geophysical Union journal Geophysical Research Letters, are... More »
