Anthropogenic Climate Change, Tuesday, 4 July 2006
In this week's Discovery, Peter Evans reports from the recent European Geosciences Union held in Vienna. Peter meets climatologist Professor Bill Ruddiman whose views about climate change have divided scientific opinion.

Land clearance and rice cultivation led to such large amounts of carbon dioxide and methane being released into the atmosphere that they countered the natural decreases that would otherwise have happened.
Controversially, Bill suggests that these emissions averted natural global cooling and prevented an Ice Age in the northern hemisphere.
