The aim of this course is to explain how the broad global system operates, in the context of life. We will study the interactions of biota, climate, oceans and rocks in the present-day world, and over the Earth's long
history. We will also consider how
the system may change over the coming centuries as a result of human influence.
Topics to be dealt with include: The role of life in the Precambrian world, mass extinctions, biotic interactions in ice ages, the
Gaia Hypothesis, the role of the
biota in the geological and contemporary carbon cycle, biological effects on ocean, atmospheric and rock chemistry, the greenhouse effect in relation to biological processes, biological acceleration of rock weathering,
vegetation-climate feedbacks, role o
f fire, effects of El Nino and NAO on the biosphere, and desertification and salinization.
