Ocean acidification: the 'evil twin' of climate change
30 April 2010
The School of Biological Sciences and NSW branch, Australian Marine Science Association present a public event on the 'evil twin of global warming' - ocean acidification.
Climate change is the result of massive amounts of carbon dioxide being released into the atmosphere by human activity. But a warmer climate, extreme weather and changes in rainfall are only part of the climate change story. The excessive amount of carbon dioxide in our atmosphere is actually changing the chemistry of the oceans, making them more acidic.
Come learn from experts in the field about the troubling issue of ocean acidification, at a public event held at the University of Sydney on Wednesday 5 May.
Marine scientist Professor Maria Byrne will present a brief introductory lecture on the science behind ocean acidification - explaining what the change in sea chemistry means for life in the ocean, and why ocean acidification poses a greater threat to our survival than temperature or sea level rise.
The introductory talk will be followed by a screening of the multi-award winning documentary A Sea Change, which uncovers the adverse effects that ocean acidification has on marine life and the catastrophic impact that will have on oceans and ocean-dependent economies. A Sea Change is the first ever documentary to be made about ocean acidification and has played to sell-out crowds at major film festivals in the US and internationally.
The NSW branch of the Australian Marine Science Association (AMSA) in conjunction with the School of Biological Sciences will host the public event, which will be held in the Eastern Ave Lecture Theatre from 6:00 pm - 8:30 pm on 5 May. Refreshments will be served in the Eastern Ave foyer from 6:00 pm and the public talk and documentary screening will take place in the Eastern Ave Lecture Theatre from 6:30 pm.
Each year AMSA holds public events with the aim of including and educating the community on issues relating to Australian marine science. The ocean acidification event will be the first public event held for 2010 by the NSW branch of AMSA.
Date: Wednesday May 5
Time: 6:00pm to 8:30pm
Location: Eastern Ave Lecture Theatre, The University of Sydney
Cost: FREE. Gold coin donation for beverages.

About the documentary "A Sea Change"
Imagine a world without fish. It's a frightening premise, and it's happening right now. A Sea Change follows the journey of retired history teacher Sven Huseby on his quest to discover what is happening to the world's oceans. After reading Elizabeth Kolbert's "The Darkening Sea", Sven becomes obsessed with the rising acidity of the oceans and what this "sea change" bodes for mankind. His quest takes him to Alaska, California, Washington, and Norway as he uncovers a worldwide crisis that most people are unaware of. Speaking with oceanographers, marine biologists, climatologists, and artists, Sven discovers that global warming is only half the story of the environmental catastrophe that awaits us. Excess carbon dioxide is dissolving in our oceans, changing sea water chemistry. The more acidic water makes it difficult for tiny creatures at the bottom of the food web to form their shells. The effects could work their way up to the fish 1 billion people depend upon for their source of protein.
