O Brave New World!

May 5, 2014 "O Brave New World! Entering An Age of Climate Change Beyond 400ppm" with Ralph Keeling, Scripps Institution of OceanographyA half century ago on a Hawaiian mountaintop, atmospheric chemist Charles David Keeling used what was then a pioneering technology to make precise measurements of atmospheric CO2. The resulting "Keeling Curve" has documented nearly 50 years of CO2 accumulation and fluctuation tied to seasonal cycles, and has had a profound and lasting impact on the study of global climate change.

Today, the research of Charles David Keeling's son, geochemist Ralph Keeling, continues to expand our knowledge of the factors influencing climate change. Join us for a special presentation with:

Ralph Keeling, Scripps Institution of Oceanography

with video commentary from Al Gore, Former U.S. Vice President
