About the Lecture
The world’s nations are gathering to pledge targets for future greenhouse gas emissions. How well can we determine whether a nation is meeting its emission targets?
Gases are mixed rapidly, albeit incompletely, in the atmosphere. This rapid mixing confounds the problem of climate treaty verification. I will review the global carbon cycle, the activities that release CO2, and how the land and oceans have absorbed about half the CO2 we have emitted into the atmosphere.
I will also review the Measurement, Reporting and Verification (MRV) of climate treaty verification. A new satellite, the Orbital Carbon Observatory 2, successfully launched on July 2 2014, delivers unprecedented observations of CO2 variations in the atmosphere. I will present a “top-down” approach for estimating carbon dioxide emissions from the atmospheric CO2 variations. Satellite and in-situ CO2 observations together with raw weather observations are assimilated into a global carbon-climate model, so that surface sources and sinks of CO2 can be inferred as required for mass conservation.
About the Speaker
Inez Fung is a Professor of Atmospheric Science at the University of California, Berkeley. She researches the interactions between climate change and biogeochemical cycles, including the hydrological cycle, modeling and observing the carbon cycle, and how dust affects marine productivity. Dr. Fung was the second woman to earn a Ph.D. in meteorology at the Massachusetts Institute of Technology, and in 2007, she shared in the Nobel Peace Prize awarded to the Intergovernmental Panel on Climate Change (IPCC). In addition, she has received the Roger Revelle Medal from the American Geophysical Union (AGU), was elected a member of the Academia Sinica in Taiwan, is a member of the National Academy of Sciences, and is a fellow of both the AGU and the American Meteorological Society (AMS).
