Speaker Dr. John Andujar, centered on a report out of Princeton University that showed how sea temperature and ocean acidification have climbed during the last three decades to levels beyond what is expected due to natural variation alone. The study looked at physical and chemical changes to the ocean that are associated with rising atmospheric carbon dioxide due to human activities. Will we see significant changes in the ocean due to climate change? Some changes are noticeable already, while others will take up to a century. Thanks to Director Warwick Butler who our speaker on this most important climate change topic.
