Scripps Scientists Participate in Historic Copenhagen Climate Change Summit
Researchers hope to inform negotiators with latest evidence on ocean acidification, black carbon, verification challenge among other topics
Scripps Institution of Oceanography / University of California, San DiegoScripps Institution of Oceanography at UC San Diego will send a delegation of scientists and students to Copenhagen for the United Nations Framework Convention on Climate Change Conference of the Parties (COP-15), which begins Dec. 7.
Along with other scientific institutions and organizations, the researchers will be on hand to interact with international negotiators on policy decisions that could dictate the world's response to climate change threats. Scripps will attend the conference as part of the UC Revelle Program on Climate Science and Policy. The conference is anticipated to produce a successor or companion emissions agreement to the 1998 Kyoto Protocol, the first commitment period of which expires in 2012.
"What the research since Kyoto tells us is that we know enough to act," said Tony Haymet, director of Scripps Institution of Oceanography and leader of the UC Revelle delegation. "We are hopeful that Copenhagen negotiators will not opt to kick the problem down the road because Scripps science suggests that there is no time for more procrastination."
The Scripps Oceanography delegation includes the following researchers:
• Tony Haymet, director, Scripps Institution of Oceanography, UC San Diego
• Victoria Fabry, professor of biological oceanography and visiting research associate
• Andrew Dickson, professor of marine chemistry
• Veerabhadran Ramanathan, distinguished professor of climate and atmospheric sciences
• Ray Weiss, distinguished professor of geochemistry
• Tamara Beitzel, student, Applied Ocean Science curricular group
• Brendan Carter, student, Marine Chemistry and Geochemistry curricular group
• Grant Galland, student, Marine Biology curricular group
• Kristina Pistone, student, Climate Science curricular group
Dickson and Fabry will provide expertise on ocean acidification, a phenomenon in which increasing carbon dioxide uptake in the oceans makes seawater more acidic. The researchers will take part in a number of informational panel discussions, film screenings and presentations that are occurring in conjunction with the U.N. conference.
Tiny marine snails called pteropods have been found by Victoria Fabry and other researchers to be especially vulnerable to changes in ocean acidity. Pteropods are a key food of many commercially important fish species.
Weiss' research indicates that a major barrier to the effectiveness of emissions regulation legislation and carbon trading lies in the large discrepancies that can exist between actual greenhouse gas emissions and those calculated by current "bottom up" accounting methods. The Scripps delegates will emphasize the need to establish "top-down" verification mechanisms based on atmospheric measurements. Such verification is essential, researchers argue, for emission regulation legislation and carbon taxes or cap-and-trade schemes to succeed. Work done by atmospheric chemists shows that current reporting of emissions can grossly misrepresent true levels of some greenhouse gas emissions in the atmosphere. Available monitoring technology, coupled with modeling of atmospheric transport, must be deployed broadly if this barrier to real greenhouse gas emissions reduction is to be removed, according to Weiss.
Ramanathan, an expert on the greenhouse effect especially from black carbon emissions, will be in Copenhagen to explain how fast-action mitigation can buy the world time as CO2 reductions take effect. He calculates that immediate reduction of non-CO2 greenhouse agents coupled with initial CO2 reduction efforts can help society avoid reaching the threshold of catastrophic climate change in coming decades. Readily available technologies ranging from biochar carbon capture to the retrofit of regenerative filters on diesel-burning vehicles to methane-capture and hydrofluorocarbon (HFC) phase-out under an updated Montreal Protocol can start the world on the path to climate stability immediately. It would also provide a clear demonstration of the human imprint on climate.
The researchers contribute to an ongoing body of evidence that climate change is not only having its projected effects but that it is trending toward the most severe scenarios forecast only two to three years ago.
Scripps climate and atmopsheric scientist V. Ramanathan is studying the effects of replacing traditional cookstoves that produce relatively large amounts of black carbon with cleaner-burning alternatives in villages like his grandmother's, Eraharam, India.
Satellite and direct measurements now demonstrate that both the Greenland and Antarctic ice sheets are losing mass and contributing to sea-level rise at an increasing rate. Additionally researchers point out that in 2008, carbon dioxide emissions from fossil fuels were about 40 percent higher than those in 1990. Even if emissions do not grow beyond today's levels, within just 20 years the world will have used up the allowable emissions to have a reasonable chance of limiting warming to less than two degrees Celsius.
Many of these findings are included in the Copenhagen Diagnosis, a synthesis of recent research compiled and issued by 26 leading international climate scientists including Richard Somerville, a distinguished professor of meteorology at Scripps. The text of the Copenhagen Diagnosis is available here.
During the conference, Scripps Oceanography will offer a website featuring the latest news and multimedia content from Copenhagen as well as blogs from participants and a reader discussion board. You can view the website here.

Scripps Institution of Oceanography, at University of California, San Diego, is one of the oldest, largest and most important centers for global science research and education in the world. The National Research Council has ranked Scripps first in faculty quality among oceanography programs nationwide Now in its second century of discovery, the scientific scope of the institution has grown to include biological, physical, chemical, geological, geophysical and atmospheric studies of the earth as a system. Hundreds of research programs covering a wide range of scientific areas are under way today in 65 countries. The institution has a staff of about 1,300, and annual expenditures of approximately $155 million from federal, state and private sources. Scripps operates one of the largest U.S. academic fleets with four oceanographic research ships and one research platform for worldwide exploration.
