Unprecedented rates of human-forced rapid climate & environmental change and extreme weather events are beyond doubt and greatly concern the international community, corporations and governments. Virtually all human activities disturb Earth’s environmental systems, increasing with the size and technical prowess of human populations since later prehistory 11,700 years ago. We are now redefining the present geological epoch as the Anthropocene as a consequence of our impact on Earth’s boundary layer ~ the instable envelope embracing the landsurface, atmosphere and oceans on which we and all other biological systems depend.

 

Global economic and political security depend on accurate scientific predictions of global environmental change, technological capacity to respond and political will to mitigate and/or adapt to impacts. The latest, 6^th Assessment Report of the Intergovernmental Panel on Climate Change in 2021 emphasises options for reducing environmental impacts, or facing consequences. Global financial crises from 2008, lack of a post-Kyoto accord (2012), excitement over natural gas fracking, tar-sand oil and Arctic Basin marine resources (made accessible by global warming!) threaten progress on carbon reduction and renewable energy, pushing us towards Dangerous Climate Change above 1.5^o C of warming. Will the 2023 CoP28 Climate Conference lead to substantial, binding targets in time?

Why have global environmental crises arisen so rapidly? What triggers dramatic increases in environmental awareness, placing environmental issues on international agendas? How can we avoid, mitigate or adapt to their effects. What happens if we cannot? Answers concern students and practitioners across socio-economic, political and natural sciences. Successful Earth Systems management and socio-economic and political stability demand we understand our environmental impact. Failure by wealthy industrialised and industrialising nations to respond to environmental impacts of sustained development raises international tension, especially amongst disadvantaged and marginalised nations.

Academic Aims

The Option’s prime aim is to extend awareness and understanding of key global environmental crises facing the international community to students irrespective of their academic backgrounds. We identify the principal components and dynamics of natural environmental systems and the context of rapid natural climate and environmental changes of the continuing Quaternary ‘Ice Age’. We examine how industrial, agricultural and other activities of human societies disrupt their operation, generating environmental disturbance. Impacts leave tell-tale environmental signatures so an important early step is to evaluate the nature of surviving evidence for environmental impacts and changes.

Establishing cause-and-effect relationships, we examine crucial aspects of global environmental crises, with particular perspectives from Europe. This most heavily industrialized and populated zone on Earth, with the longest continuous records of human occupation since the most recent world-wide Ice Age means that many origins and consequences of rapid environmental change are found here.

Academic Programme

Key Lectures and Seminars provide a general review of the principal themes, which students then explore in more detail in Tutorial essays or seminar papers, choosing a weekly topic from the list below:

Week 2: Climate Change: past & present

Key Illustrated Lecture: Intergovernmental Panel on Climate Change: Science, Impacts & Mitigations

Seminar/Tutorial: Quaternary cold & temperate stages. Holocene climate ~ the past 11,700 yrs.
