Term had kicked off in Oxford and here are two lectures I have just given in the opening week series "Welcome to the Anthropocene"
A short history of the biosphere (35 MB).
This lecture is part of the “Welcome to the Anthropocene” series on “Introduction to timescales”. In this lecture, I address such topics as: (1) key components of the biosphere over Earth’s history, from evolution of photosynthesis to present. (2) Mass extinctions and periods of rapid climate change - the Palaeocene-Eocene thermal maximum and glaciations. (3) Contemporary global change in the context of Earth history. (4) The concept of the Anthropocene.
The metabolism of a human-dominated planet (56 MB)
This lecture explores how human activity and use of the biosphere has changed through human history and pre-history, through hunter-gatherer, agrarian and industrial modes of society. I discuss the concept of describing human activity and material and energy use through social metabolism, and compare with the inherent biological metabolism of the biosphere. I explore a range of ideas and bizarre questions such as: to what extent can human societies be considered as superorganisms? In what way are cities more like stars rather than like ant colonies?
