What affects the atmospheric and ocean flows? This free course, Environment: understanding atmospheric and ocean flows, explores the mechanisms that are important; the most rapid carrier is the wind. The basic principle of global atmospheric circulation is simple: warm air rises and cold air sinks. How does this principle affect the atmosphere and flow of water in practical terms? Starting with an iconic environmental icon, the polar bear, you will learn how global flows of water, heat and pollution are affecting the Arctic region and changing our world.
Environment: treading lightly on the Earth focuses on the problem of greenhouse gas emissions, especially carbon dioxide. This free course will give you an understanding of the nature and importance of carbon footprints of individuals and households. It will enable you to measure your own carbon footprint and explore what you could do to reduce that footprint and so ‘tread more lightly on the Earth’.
This free course, Waste management and environmentalism in China, is an introduction to waste generation and waste management processes currently being practiced in China. This course explores how the Chinese can deal with increasing volumes of waste, drawing parallels with the UK experience of waste management. It also discusses the conceptual tools that can be used to make the cycle of material use, waste production and treatment more sustainable. The course ends with a brief examination of the growth of environmentalism in China.
The oceans cover more than 70 per cent of our planet. In this free course, The oceans, you will learn about the depths of the oceans and the properties of the water that fills them, what drives the ocean circulation and how the oceans influence our climate.
This free course is a general introduction to the frozen planet, including the temperature in the polar regions; the energy from the Sun and the seasons; reading and understanding graphs and maps; and how the Arctic and Antarctic regions are defined.
This free course explores the relationship between China and the United States and analyses whether China’s rapid rise will lead to greater cooperation or conflict with the US. The answer to this question will have profound implications for both countries and the wider international system. The course introduces some of the contemporary issues in China-US relations and provides historical background on the evolution of relations between the two countries. It introduces and applies some key ideas drawn from the discipline of International Relations relating to interdependence to ------ the prospects for the future trajectory of relations between these two major powers.
This free course, ‘Land grab’: an environmental issue?, explores how environmental problems are entangled with economic and political issues and offers tools for making sense of the complexity that results. The case of land grab illustrates how everyday issues such as food prices are caught up in connections that link different places, different people and their livelihoods across the globe; connections that are brought to life in the course through rich audio-visual material and interactive activities.
