Dr Thomas Smith CKK4.18

This course is compulsory on the BSc in Environment and Development, BSc in Environment and Sustainable Development, BSc in Environment and Sustainable Development with Economics and BSc in Environmental Policy with Economics. This course is available on the BA in Geography. This course is available as an outside option to students on other programmes where regulations permit and to General Course students.

Many consider that ‘Climate Change’ is the greatest challenge currently facing human society, mainly because of the ‘Environmental Changes’ that it will cause. But what are ‘Climate Change’ and ‘Environmental Change’? What causes these changes? How much have they changed in the past and how do we know? How much is human activity responsible for the recent changes identified and when did this influence begin? How is the climate going to change in the next century and what are the consequences going to be for extreme weather events, sea-level rise? What can we do about it? Should we adapt, mitigate, or begin to engineer our climate?

To answer these questions requires that the course focuses on developing an appreciation of the Planet Earth as the home of human societies. Through a combination of lectures, classes, practical work, and fieldwork, the course focuses on the physical nature of the 'natural' or biophysical systems and involves consideration of how the solid earth, the gaseous atmosphere, the hydrosphere and the biosphere, were formed, have evolved, interact and have changed over time due to both external (extra-terrestrial) and internal factors, including humans. From this, an appreciation of change and evolution over differing time-scales is developed, which will serve as an essential basis for students when evaluating the contemporary two-way interaction between humans and the environment in the ‘anthropocene’. The relevant science will be taught as and when required.

The course consists of the following sections:

PART A: Introduction to environmental change

• A framework for environmental geography
• The nature and causes of environmental/climate change

PART B: Key components of environmental change: The Biosphere

• Formation of the biosphere and change over time
• Contemporary ecosystem processes and change
• The biodiversity crisis: extreme change in the anthropocene

PART C: Key components of environmental change: Atmosphere & Oceans

• Solar radiation, the atmosphere, and interactions
• Global and local energy budgets
• Circulation - atmosphere, oceans, and carbon

PART D: Key components of environmental change: The Hydrosphere

• Water in the atmosphere, clouds and rainfall
• Hyrological cascade, rivers and flooding

PART E: Long-term environmental change

• Geological-scale climate change and Earth's 'greenhouse' and 'icehouse' environments.
• Orbital-scale climate change and the great ice ages
• Millenial-scale climate change and deglaciation

PART F: Contemporary climate change: The emerging human influence

• The Holocene
• Contemporary climate change associated with fossil fuel emissions
• Contemporary climate change and extreme weather
• Land-use and land-cover change (deforestation)

PART G: Future climate change

• Modelling future climate change
• Fixing the future: Adaptation, mitigation, and geoengineering

In the Department of Geography and Environment, teaching will be delivered through a combination of classes/seminars, pre-recorded lectures, live online lectures, in-person lectures and other supplementary interactive live activities.

This course is delivered through a combination of classes and lectures across Autumn and Winter Term.

This course includes a reading week in Week 6 of Autumn Term and Week 6 of Winter Term.

Students will be expected to produce two assignments during the year, one in each term, and give class papers.
