{"ModuleCode":"GEK1535","ModuleTitle":"Our Atmosphere: A Chemical Perspective","Department":"Chemistry","ModuleDescription":"After reading this module, students will have developed a deeper knowledge and a greater appreciation of the atmosphere. They will leave the course with a general understanding of some principals of elementary chemistry and perhaps some insight into how science is used to guide government policy. Topics are varied, but include global warming, the ozone hole, air pollution, the Gaia hypothesis, eco-philosophy and environmental politics. No students are excluded. Only an elementary knowledge of science is assumed.","ModuleCredit":"4","Workload":"3-1-0-0-6","Prerequisite":"Available to all

We will look at how our atmosphere evolved to support life and how, latterly, life’s highest form has been impacting upon its evolution. After reading this module, students will understand the science behind many of the environmental problems facing society, including global warming and the ozone hole. We will look at the intimate relationship between the atmosphere, the oceans and the biosphere. A relationship that has led some to regard the Earth as a self-regulating organism. The module will be largely self-contained and only an elementary knowledge of science will be required.

It was from our studies of the atmosphere that led to the emergence of chemistry as a distinct, rational science. In the last century, our studies of the atmosphere centred largely on understanding the distribution of ozone. Ozone plays two roles in the atmosphere: first, in the stratosphere it protects us from potentially lethal ultraviolet radiation; and second, in the troposphere it is a significant pollutant with impacts, inter alia, on both human health and agriculture. In 1985, scientists discovered dramatic ozone depletion over Antarctica during spring in the now infamous ‘ozone hole’ events. The ozone hole is arguably the single most important event in environmental politics. It galvanised support that led to the formulation of the first-ever global, international treaty on an environmental issue. This treaty, the Montreal Protocol, is providing the framework for governments in their attempts to limit the emissions of greenhouse gases and thus mitigate global warming. Whether or not ozone depletion was the environmental issue of the last century, without a doubt, global warming will be this century. All these issues — historical, political and scientific — will be covered in an entertaining and absorbing manner in a module that will give students a deeper knowledge and appreciation of our atmosphere.
