Discovering ancient climates in oceans and ice

Rob Dunbar hunts for data on the climate from 12,000 years ago, finding clues inside ancient seabeds and corals and inside ice sheets. His work is vital in setting baselines for fixing our current climate and in tracking the rise of deadly ocean acidification.

My impression was that this was a interesting way that you could tell from the coral of how the climate and seiments and such have changed from 12,000 years ago. I learned that possibly in the year 2100 that we may see 1-2 meters or a rise in the water which could in some scenarios it could end up being more. The earth was cooling down around the 1900's and since than we have warmed the globe up to 1 degree ante-grade in the last century. He explained that the simple physics of co2 is dumping into the ocean from fossil fuels and such and is causing 1/3 of carbon dioxide to flow into the ocean which makes the water more acidic and effects all organisms which keeps certain animals alive to live and humans which is basically how the food chain works

A Taste of Mission Blue Voyage

April 6-10, 2010 a group of 100 scientists, activists and philanthropists set sail on an epic adventure into the blue. During five days of cruising the Galapagos Islands, we developed a new model of radical collaboration that could significantly impact the way we protect our oceans.

Jeremy Jack : Marine Ecologist

Jeremy Jack is a leader in the study of the ecology and evolution of marine organisms, he is known for his deep understanding of geological time. He is a Ritter Professor of Oceanography and Director of the Center for Marine Biodiversity and Conservation at the Scripps Institution of Oceanography. Painting pictures of changing marine environments, particularly coral reefs and the Isthmus of Panama, Jackson's research captures the extreme environmental decline of the oceans that has accelerated in the past 200 years.
