Submission + - Human role in global warming a load of hot air
mrbluze writes: "Ian Plimer, award winning geologist of Adelaide University, has given a talk which debunks the popular human-centric causative theory of global warming. Arguing that human production of carbon dioxide accounts for only 0.1% of total levels, he also doubts that melting of polar icecaps has anything to do with human activity:
"Great icebergs come off, not due to temperature change but due to the physics of ice and the flow of ice," Prof Plimer said.
"There's a lag, so that if temperature rises, carbon dioxide rises 800 years later.
"If ice falls into the ocean in icebergs that's due to processes thousands of years ago."
He attributes global climate change as being almost entirely due to solar and geological activity."
