Sustainable Living Seminar: Lethal Seas

A deadly recipe threatens the survival of countless creatures throughout Earth’s oceans:  carbon dioxide.  With carbon emissions sharply rising, this silent killer is entering the seas at a staggering rate, raising the ocean’s acidity.  As a result, the skeletons and shells of marine creatures that form the foundation of the web of life are dissolving.  Can experts crack the code of a rapidly changing ocean before it is too late?  Come see “Lethal Seas” to hear what is happening and what we can do to prevent it.

After the viewing of "Lethal Seas", oceanography professor, Bill Gilhooly, Department of Earth Sciences at IUPUI, will highlight a few points about ocean acidification, and answer your questions.  As a follow-up action, we'll  discuss ways we can help by reducing our carbon emissions.

This program is part of The White River Festival. River waters eventually lead to the ocean. Actions we take to protect the oceans from acidification will also protect the White River from global warming, mercury pollution and acid rain. Click here to see other White River Festival events.

  • Predicting Future Oceans This report published in the journal Science compared the future of the oceans under two climate change scenarios. In one scenario, we limit atmospheric warming to two degrees by 2100, as outlined by the Copenhagen accord. In the other, we continue with the current high CO2 emissions, which researchers say would cause a five-degree increase in atmospheric temperatures. They say if warming continues unchecked, fish will migrate away from their current habitats 65 per cent faster, resulting in changes to biodiversity and ecosystem functions. In addition, the acidity of the world’s oceans, as measured by pH, is likely to decrease by 0.33 units by the end of the century, a rate that is unprecedented over the past millions of years.  The report is intended to inform discussions at the upcoming 2015 United Nations Climate Change Conference in Paris.
  • Contrasting futures for oceans and society from different anthropogenic CO2 emissions scenarios Science, July 3, 2015 - "The management options to address ocean impacts narrow as the ocean warms and acidifies. Consequently, any new climate regime that fails to minimize ocean impacts would be incomplete and inadequate."
