In a study led by Lauren T. Toth at Florida Institute of Technology published in the journal, Science, coral reef ecosystems in the tropical eastern Pacific “collapsed for 2500 years, representing as much as 40% of their history, beginning about 4000 years ago.” A series of powerful El Nino events, which include periods of significantly warmer ocean temperature every three to seven years, coincided with the 2,500-year period of coral decline. This was followed by a cycle of La Nina events characterized by much cooler water, beginning 3,200 to 3,800 years ago. Corals recovered during the millenia since but now face a return to extreme weather conditions like those that wiped them out, due to climate change impacts. Read more

Roz Savage aboard Brocade in the PacificOn May 25, 2008, Roz Savage rowed beneath the Golden Gate Bridge and into the Pacific Ocean, which she is now attempting to cross — rowing solo. She has already completed such a journey across the Atlantic, and is using her adventures to raise awareness of environmental issues and inspire others to rise to their own challenges. Our friends at Blue Frontier Campaign, including its founder, David Helvarg, have been keenly engaged in Roz’s journey and working with Roz to make sure that her journey brings strong awareness about the oceans. (1planet1ocean president David E. Guggenheim is a member of Blue Frontier Campaign’s Advisory Council).
As a courtesy to Roz and her many fans around the world, 1planet1ocean has assembled a special tracking page to help you track and participate in Roz’s incredible journey. You’ll find an interactive Google map, and you can even track her adventures using Google Earth. The map has links to Roz’s photos and to her blog posts, which she is continuing to provide via satellite from sea. For more information, please be sure to visit Roz’s web site.
