DGE Newsletter, September 2009
Field & Berry Groups
Dr. Kris Ebi, the Executive Director of the Technical Support unit for WG2 of the IPCC arrived at DGE in mid August. She has been in this position for the last several months, working from Washington DC. For Kris, an expert in climate change and Sept. 3: Dr. Josep Peñuelas, the leading ecologist in Spain, arrived for a short sabbatical in the Field Lab. He is Research Professor, National Research Council of Spain, Director, Plant Ecophysiology and Global Change Unit, Center for Ecological
human health, this is something of a homecoming, as she spent several years with the Electric Power Research Institute, in Palo Alto.
Sept. 29: Kristie gave us a Seminar titled A Stitch in Time: Human Adaptation to the Health Risks of Climate Change. She enumerated various diseases which would increase as a result of the direct effects of Climate Change (temperature & precipitation) by drawing upon her extensive background with the WHO, USAID & the Millennium Ecosystem Assessment as well as work in toxicology and tropical medicine.
Sept. 8: Chris Field was a Keynote Speaker on the first day of the 3-day, 6th Annual California Climate Change Symposium at the Sacramento Convention Center. He shared his insights on the strategy that his working group will use for the preparation of the Impacts and Adaptation Report of the next IPCC Assessment.
Every year, the California Energy Commission organizes a conference on new science concerning climate change in California. The opening session had remarks from the Chairs of the California Energy Commission, the Resources Agency, the Air Resources Board, and Chris.
On Sept. 9, Kimberly Cahill now at the Univ. Calif. Davis spoke to the title: Climate and Wine Grape Phenology in the Napa Valley during a Session called Observed Climate Change Impacts in the 20th Century.
On Sept. 10, Rebecca Shaw (Stanford University) spoke about Ecological Services during a Session called Economic Impacts: II
Research and Forestry Applications, Universitat Autònoma de Barcelona. His seminar was titled: Neglected biological components of ecosystem - global change interactions. Dr. Peñuelas sketched the work of his large group including the relationships of climate change to the atmosphere, biosphere, land use, and biodiversity in both directions.
Sept. 22: Dr. James Johnstone, Dept. Environmental Science, Policy, & Management, UC Berkeley spoke about his research on the Summer fog variability in the coast redwood region: Climatic relevance and ecological implications.
He has been able to collect quantitative data of the amount of fog daily along the US west coast from airport records going back decades and correlate these records with other meteorological measurements. This ongoing study already shows some effects of climate change.
Caldeira Group
Sept. 3: Ho-Jeong Shin writes that after enjoying the GEWEX conference in Australia, she moved on to the Indian Institute for Science in Bangalore. There she was planning to continue the fast response study on hydrological cycles, and with Bala, decided to perform SCAM experiments after learning how to deal with SCAM. The Institute is located in a jungle (kidding), and the campus is beautiful. She could see monkeys in the guest house. Photos to follow.
Asner Group

Sept. 7: Greg Asner sends a recent paper* on a strategy for rapid carbon assessment in tropical forests. The method is designed to run at the sub-national level for UNFCCC REDD and similar upcoming programs. Results using the strategy are forthcoming from our group's over 1,000,000 ha experiment in Hawaii. We’re in the Peruvian Amazon now using the same strategy in a 4,200,000 ha REDD demonstration project. Stay tuned. *Environ. Res. Lett. 4 (2009) 034009 (11 pp) Tropical forest carbon assessment: integrating satellite and airborne mapping approaches.

Alumni News

Sept. 25: Alum David Kroodsma writes about his latest activities including The Book (Ride for Climate), A New Video, Brita Climate Ride, and a climate bike rally in DC with 12 ambassadors and 2 senators on Sept. 30. You may follow all this and more on
