DGE In-House Seminars

Sept. 12: Kate Ricke, a new postdoc in Caldeira’s Group from Carnegie MellonUniversity, described her recent and current research with Solar Radiation Models. This is particularly important in relation to geoengineering.


Sept. 19: Vineet Yadav who received his PhD from the University of Iowa, became a post doc with Dr. Michalak and came here with her from Michigan, reported on his recent research, Nowcasting Global Carbon Fluxes. Vineet is modeling global estimates of CO2 exchange of at least 8-day intervals using multiple data assimilation algorithms. He demonstrated (1) A real time system producing maps of CO2 flux, (2) A modular data assimilation system where different transport models and data assimilation methods can be swapped, and (3) An intelligent system to analyze maps of CO2 flux.

Sept. 26: Kelly McManus gave us a Power Point show of her eight weeks spent in Costa Rica with a class of 20 students & many instructors titled: Investigations in Neotropical Forest Environments. She had experimental, hands-on experience with gardening preferences, identifying algae, & collecting Lidar data, and hopes to continue this study in Panama. Sounds like a great Program.


Sept. 22: When this photo of David Kroodsma (one of DGE's first Master's Degree students) was taken about four years ago he was about to embark on his mission of broadcasting Climate Change & its effects to the people of the Americas by bicycling from Palo Alto, CA to the tip South America. Dave & his father had already biked across the US. Today he is highlighted in the Huffington Post with this excerpt:" David Kroodsma is a data journalist at Climate Central, a collaboration of scientists and journalists communicating climate science to the public. His job is to tell stories using relevant climate data, including through the use of interactive maps, apps and widgets." You can follow him on Twitter or at










Caldeira Group

Sept. 2: Your editor visited DGE’s 2nd floor conference room to watch Ken Caldeira film Stanford’s Roz Naylor discussing biofuels for 2:48 min on YouTube. Ken and Julia Pongratz quickly transformed the room into a film studio with several tripods to hold lights, backdrop screen, camera and microphones. You can see the results of their work at <>.  If you have ideas for more such videos, talk to Ken because he may set up the studio again about once/month.
Sept. 11: Here is the full set of videos Ken made of the interview with Roz Naylor on 2 Sep 2011 for Near Zero's YouTube channel:Biofuels, land-use, and economic transition: Roz Naylor speaks to Near Zero (4:53)
Climate and crops, diversification and irrigation: Roz Naylor speaks to Near Zero (5:47)
Biomass supply and demand: Roz Naylor speaks to Near Zero (3:50)
Biofuels, food prices, and the poor: Roz Naylor speaks to Near Zero (2:24)
Trade-offs between food and biofuels: Roz Naylor speaks to Near Zero (2:48)

Field and Berry Group

Sept. 26: This first Lab meeting of the Fall Quarter was for planning. After several suggestions and discussion, it was decided to talk and read about Geoengineering Technology and Climate Mitigation Models. Aaron Strong plans to lead off on Oct.3 with the 2009 Royal Society Report on "Geoengineering: Science, Governance, Uncertainty."
The Group is also planning a field trip later in October to the White Mts east of the Sierra to see the famous, ancient Bristlecone Pines .

Sept. 9: FYI -- EESS is hosting a seminar course (EARTHSYS 201) this coming semester on the IPCC that will feature presentations from IPCC authors on the 5th Assessment Report.  The course will take place Thurs at 4:15 - 5:30 pm in room Y2E2 101.  Speakers include Chris, Ken Caldeira, Mike Mastrandrea and Katie Mach, David Lobell, Terry Root, Noah Diffenbaugh, John Weyant, Kirk Smith, Max Auffhammer, Rebecca Shaw, and others.
