Short biography:

Thompson completed a PhD in Atmospheric Chemistry at Victoria University of Wellington, New Zealand, in 2005. Following her PhD, she held two post-doctoral positions, first at the Max-Planck Institute for Biogeochemistry in Germany, and then at the Laboratoire des Sciences du Climat et l’Environnement in France. Since 2011, Thompson is a senior scientist at the Norwegian Institute for Air Research, where her research is focused on the estimation of sources and sinks of various greenhouse gases using atmospheric observations. Specifically, she uses the atmospheric inversion approach and has applied this to studying the fluxes of CO2, CH4 and N2O, as well as to the emissions of synthetic trace gases. Thompson serves on the IG3IS steering committee and is a co-leader of the Global Carbon Project N2O budget. She is also an author on the IPCC AR6.


A new comprehensive assessment of the nitrous oxide (N2O) budget has found that emissions from human activities, in particular agriculture, have increased 30% since the 1980s. The rate of increase exceeds even the most pessimistic of IPCC scenarios. What does this mean for the goals of the Paris agreement and where have the largest emission increases occurred?
