About the video: ‘What are ‘climate feedbacks’?’
David Wasdell explains how the future of our climate will be affected by feedback mechanisms that may amplify global warming. Of the 20 feedback mechanisms that have been identified, Wasdell describes the most significant. These include the Albedo Effect, or the way in which ice reflects the solar radiation back into the atmosphere. Other feedbacks mentioned relate to water – for instance how water vapour amplifies the greenhouse effect, and why the acidification of the World’s oceans can hamper the absorption of Carbon Dioxide.
