High Quality Content by WIKIPEDIA articles! Colin J. Campbell, PhD Oxford, (born in Berlin, Germany in 1931) is a retired British petroleum geologist who predicted that oil production would peak by 2007. He claims the consequences of this are uncertain but drastic, due to the world`s dependency on fossil fuels for the vast majority of its energy. His theories have received wide attention but are disputed and have not significantly changed governmental energy policies at this time. In order to deal with declining global oil production, he has proposed the Rimini protocol.
