A Simplified Model To Predict the Effect of Increasing Atmospheric CO2 on Carbonate Chemistry in the Ocean  Brian J. Bozlee, Maria Janebo, and Ginger Jahn
The chemistry of dissolved inorganic carbon in seawater is reviewed and used to predict the potential effect of rising levels of carbon dioxide in the atmosphere. It is found that calcium carbonate may become unsaturated in cold surface seawater by the year 2100, resulting in the destruction of calcifying organisms such as coral.

"Holes" in Student Understanding: Addressing Prevalent Misconceptions Regarding Atmospheric Environmental Chemistry  Sara C. Kerr and Kenneth A. Walz
This study evaluated the misconception that global warming is caused by holes in the ozone layer, other ideas surrounding atmospheric chemistry that are responsible for the entanglement of the greenhouse effect and ozone depletion in students' conceptual frameworks, and the effectiveness of computer-based online data-analysis exercises to address these shortcomings.

A Simple Calorimetric Experiment That Highlights Aspects of Global Heat Retention and Global Warming  Joel D. Burley and Harold S. Johnston
In this laboratory experiment, general chemistry students verify that heat is consumed in the melting of ice, with no increase in temperature until all the ice has melted. The fundamental calorimetric principles demonstrated by the lab results are then developed to help students better assess and understand the experimental evidence associated with global warming.

Greenhouse Gases and Non-gray Behavior  J. C. Jones
Greenhouse gases feature in many courses in applied chemistry as well as in courses on environmental science, atmospheric chemistry, and so on. We hear a great deal about such matters from the media. A more classical topic which first-year chemistry students will learn about in the physical chemistry component of their program is the black body concept and the StefanĀBoltzmann law. Recently in teaching about greenhouse gases to MSc students I have thought of a link between the topical and classical matters that is pedagogically interesting and might be of value to others teaching in this subject area.

Water in the Atmosphere  Joel M. Kauffman
None of eight college-level general chemistry texts gave a mean value for water in the atmosphere, despite its being the third most prevalent constituent at about 1.5% by mass as vapor and about 2% if clouds and ice crystals are included. The importance of water as a greenhouse gas was omitted or marginalized by five of the eight texts. An infrared spectrum of humid air was determined to demonstrate that water vapor, because of its higher concentration, was more absorptive than carbon dioxide. The cooling effect of clouds, or other influences on the Earth's albedo, were not mentioned in most of the texts. These pervasive errors should be corrected in new or future editions of textbooks.

Thermal Physics (and Some Chemistry) of the Atmosphere  Stephen K. Lower
An exploration of how the temperature of the atmosphere varies with altitude can serve as a useful means of illustrating some important principles relating to the behavior of gases and to the absorption and transformation of radiant energy.

Environmental chemistry in the classroom  Day, Jean W.
The environmental sciences is an especially good vehicle for relating chemistry to other disciplines in courses for nonscientists.
