Description - summary of the module content

Module description

This module will provide you with an introductory understanding of the development of the Earth System over the past 4.5 billion years. The module examines the role of the Sun, the inner Earth, and the evolution of life, in shaping the Earth system and creating a world in which humans could evolve. It explores the causes of past climate changes on all timescales, with a special focus on the recent Quaternary ice age cycles (the last 2.5 million years).

Module aims - intentions of the module

This module aims to provide you with an introductory understanding of how the Earth has developed as a system, what the key parts and processes in that system are, and what the key drivers of change in the system have been in the past. It provides an introduction to ‘systems thinking’ including the role of feedback processes in stabilising or destabilising our planet. Earth System Science: The History of our Planet aims to provide you with much of the background understanding required for a degree in Physical Geography.

Through active participation in the module, the aim is that you will further develop the following academic and professional skills:

  • systems thinking (being able to conceptualise a whole system and understand how it functions)
  • problem solving (developing own ideas with confidence, identifying and using appropriate sources of information, selectively collecting and collating appropriate information)
  • managing structure (identifying key demands of the task, setting clearly defined goals,  conceptualising central issues within the task, developing strategies to ensure individual progress)
  • time management (managing time effectively individually and in a group)
  • collaboration (respecting the views and values of others, taking initiative and leading others, supporting others in their work, maintaining group cohesiveness and purpose)
  • the application of critical analytical skills in relation to reconstructing the history of our planet

The teaching contributions on this module involve elements of research undertaken by module staff, such as work on the coupled evolution of life and the planet (Lenton), the reconstruction of Quaternary environmental changes (Jones), and an Earth system view of the Anthropocene (Lenton, Jones). Moreover, you are encouraged to undertake enquiry-led learning, specifically through the reading of research articles as well as lecture material.

Syllabus plan

Syllabus plan

The module divides into two parts: Deep time Earth system dynamics, and Quaternary Earth system dynamics.

The deep time Earth system dynamics component covers:

  • Birth of the Earth system
  • The origin of life
  • Solid Earth dynamics
  • The Gaia hypothesis
  • The faint young sun puzzle
  • The rise of oxygen
  • The snowball Earth hypothesis
  • Plants cool the planet
  • Oxygen regulation
  • Rolls of the dice: extinction events
  • Turmoil in the greenhouse: hyper-thermals
  • Descent into the icehouse.

The Quaternary Earth system dynamics component covers:

  • Palaeo-environmental reconstruction; archives and proxies
  • Climate change in the Quaternary
  • Human evolution and climate change in the Quaternary
  • Quaternary climate change in Europe and North America
  • The Quaternary in Asia and the Tropics
  • Interglacials – an analogue for the future?
  • Rapid climate change and the last deglaciation
  • Climate change and the present interglacial
  • The dawn of the Anthropocene
  • Climate change in the Holocene - societal impacts
  • The last millennium

Re-assessment notes

Deferral – if you miss an assessment for certificated reasons judged acceptable by the Mitigation Committee, you will normally be either deferred in the assessment or an extension may be granted. The mark given for a re-assessment taken as a result of deferral will not be capped and will be treated as it would be if it were your first attempt at the assessment.

Referral – if you have failed the module overall (i.e. a final overall module mark of less than 40%) you will be required to sit a further examination. If you are successful on referral, your overall module mark will be capped at 40%.
