The Environmentalist might say that the human race is
despoiling the planet but if you look at the history and geology of the planet
since its creation, it is not always a one-way process. This course aims to
provide a scientific background to some natural events, both geological and
historical, that have affected the human race and the biosphere. You will also
discuss the influence that mankind is now having on the planet's environment.
The intention will be to provide a better understanding of factors influencing
these events, their causes and possible future impacts.
This synopsis covers the main topics that are included in
the presentations. My aim is to make a presentation of about 45 minutes in each
session and allow plenty of time for discussion. Our lecture room has wifi so
if anyone wishes to bring i-pads, i-phones, or laptops, we can obtain
additional information to resolve a discussion. I do not have all the
answers!
A scientific background is not a precondition as I hope
to introduce all the topics in an easily understandable way.

Reading List
As so many subjects are to be covered on this course, a
comprehensive reading list would be required which might look rather daunting. Whilst I will be recommending some books
during the course after introducing the subject, anyone who in the interim wishes to see my reading list can contact me
