Earth Sciences

AIMS

To provide a thorough understanding of the mechanisms of and responses to Palaeoclimate - climate change through geological history, with special emphasis on understanding the processes which shaped the surface of the Earth (past and present), which control the environments we are living in and which contribute significantly to our understanding of how life evolved.

OUTCOMES

The students should be able to:

• recognize and understand palaeoclimate - climate signals in the geological record and in recent climate archives;
• know how to critically evaluate and interpret these data;
• know how to assess these data for their impact on Earth’s systems, surface processes, environmental change, evolution of life, and modern society.

CONTENT

Palaeoclimate studies provide direct evidence of how the climate system changes through time, including its responses to unprecedented changes in its control. This course explores the basic climatic responses of Earth’s major systems and subsystems (ice, water, air, vegetation and land), and traces their interactions through time. The range and causes of past natural climatic variability, the past sensitivity of the climate systems to various forcing, variations in climate feedbacks through time, and the responses of ecosystems and human societies to past climate variability will be presented and discussed within major themes, e.g. tectonic-scale change, the sedimentary response, orbital- , deglacial -, and millennial- scale changes, historical and future change.
