For this lesson, the guiding Concept Question is: What is climate change and how does climate relate to greenhouse gas concentrations over time? This activity is the second lesson in a nine-lesson module 'Visualizing and Understanding the Science of Climate Change' produced by the International Year of Chemistry project (2011).
On September 27, 2013, Working Group I of the Intergovernmental Panel on Climate Change (IPCC) presented its report to member governments for approval and acceptance. The report is the first of four that will make up the IPCC's 5th Assessment.
Carbon Dioxide Information Analysis Center (CDIAC)
December 28, 2012
The CDIAC is the primary global-change data and information analysis center of the U.S. Department of Energy (DOE). It contains information on concentrations of carbon dioxide and other radioactively active gases in the atmosphere; the role of the terrestrial biosphere and the oceans in the biogeochemical cycles of greenhouse gases; emissions of carbon dioxide to the atmosphere; long-term climate trends; the effects of elevated carbon dioxide on vegetation; and the vulnerability of coastal areas to rising sea level.
In this hands-on engineering activity, students will build a tabletop wind turbine. Students get acquainted with the basics of wind energy and power production by fabricating and testing various blade designs for table-top windmills constructed from one-inch PVC pipe and balsa wood (or recycled materials). The activity includes lots of good media and Web resources supporting the science content.
In this Earth Exploration Toolbook chapter, students select, explore, and analyze satellite imagery. They do so in the context of a case study of the origins of atmospheric carbon monoxide and aerosols, tiny solid airborne particles such as smoke from forest fires and dust from desert wind storms. They use the software tool ImageJ to animate a year of monthly images of aerosol data and then compare the animation to one created for monthly images of carbon monoxide data.
In this hands-on activity, participants learn the characteristics of the five layers of the atmosphere and make illustrations to represent them. They roll the drawings and place them in clear plastic cylinders, and then stack the cylinders to make a model column of the atmosphere.
This video illustrates how atmospheric particles, or aerosols (such as black carbon, sulfates, dust, fog), can affect the energy balance of Earth regionally, and the implications for surface temperature warming and cooling.
This is the most recent assessment of ozone depletion. Produced by the WMO and UNEP every four years since 1985, the assessment is the work of over 300 scientists including some from NOAA. The 2010 report highlights advances in the understanding of the role greenhouse gases play in ozone alteration. It also includes updated information for policymakers including ozone projections for the 21st century.
Atmospheric Aerosol Properties and Climate Impacts
January 15, 2009
A detailed look at global distributions and properties of airborne particles known as "aerosols." The report examines the various ways in which aerosols influence climate, and the uncertainties in our ability to observe and measure these particles' impact on the climate system.
