Dr Josep G. Canadell is the Executive Director of the Global Carbon Project and a chief research scientist at the Commonwealth Scientific and Industrial Research Organization in Australia. His work focuses on collaborative and integrative research to study the human perturbation of the carbon cycle and the global budgets of carbon, methane and nitrous oxide. Additional interest is on assessing the size and vulnerability of earth's carbon pools and pathways to decarbonization. He has contributed to the last three Assessment Reports of the IPCC and publishes in the field of global ecology and earth system sciences.

Dr Dan Hayes is Associate Professor in the School of Forest Resources at the University of Maine. He teaches, does research and performs outreach on the use of remote sensing for forest inventory and ecosystem studies. He studies the role of climate change and disturbance in the dynamics of terrestrial ecosystems, with a focus on Arctic and Boreal regions. He has contributed to various regional, continental and global carbon budget modeling and synthesis efforts and publishes on the methods and results of multi-disciplinary, ecosystem-scale scientific investigations.

Dr Rona Thompson is a senior research scientist at the Norwegian Institute for Air Research. Her research focuses on the modelling of atmospheric transport and composition, especially greenhouse gases, and improving knowledge of the sources and sinks of various atmospheric species using statistical optimization methods. She was a contributing author to the last two Assessment Reports of the Intergovernmental Panel on Climate Change and has published numerous articles on the emissions and atmospheric transport of greenhouse gases.
