Jason Hall-Spencer speaks about ocean acidification

By Jason Hall-Spencer, 25th July 2012

Save Our Seas Supported Project Leader Professor Jason Hall-Spencer is an authority on ocean acidification.

Our seas currently absorb over 25 million tons of CO2 every day. This has caused surface waters to become 30% more acidic since wide-spread burning of fossil fuels began. As well as lowering pH, increased CO2 levels are altering surface water chemistry. Falling carbonate levels are a major conservation concern since these are the building-blocks of shells for marine organisms from tiny coccolithophores to giant coral reefs.

Recently, Jason was interviewed during Rio+20 – United Nations Conference on Sustainable Development.

Jason speaks about ocean acidification, why this is such a major threat and how important research in this field is.
