CPDN contributes to US NAS Annual Meeting & IPCC Sixth Assessment Report Scoping Meeting

Dr Friederike Otto, Deputy Director and Senior Researcher in the University of Oxford's Environmental Change Institute, recently contributed to the IPCC's Scoping Meeting in Addis Ababa (Ethiopia) to draft the outline of its Sixth Assessment Report and to the US National Academy of Sciences Annual Meeting breakout session on extreme event attribution in Washington D.C.

Dr Otto, who works with the Centre's Energy and Environmental Informatics Research Group on the volunteer computing, climate modelling project climateprediction.net (CPDN), showcased at both meetings her world leading expertise around extreme events, attribution and risk assessment.

The NAS Annual Meeting breakout session on extreme event attribution was a follow up to a previous workshop in 2016, for which Dr Otto was also a leading contributor and which released as summary a report on the attribution of extreme weather relating to climate change. The breakout session examined how the science of extreme event attribution has progressed since the release of the previous report, and whether the report has had influence on how extreme weather events are attributed and discussed.

Dr Otto said in the session that studies and assessments such as those carried out by CPDN are useful in determining the impacts of climate change today, and to assist with decisions being made in particular regions of the world with respect to very specific types of extreme event – for example, whether better flood defences are needed in a particular region.

Directly following the NAS meeting Dr Otto travelled to Addis Ababa, Ethiopia to participate in the Intergovernmental Panel on Climate Change (IPCC) 6th Assessment Report scoping meeting. The Assessment Reports are published materials composed of the full scientific and technical assessment of climate change. As one of 60 global experts on the physical science basis of climate change chosen from over 600 nominations by the IPCC, Dr Otto was one of the UK's representatives in Working Group One. The outlines of each working group were designed and debated both in specific breakout sessions and then in plenary sessions and will be formerly ratified in the IPCC plenary session in Montreal in September 2017.

Dr Otto says, "It is to no small degree thanks to the unique capability of running very large ensembles of regional climate simulations with weather@home that I and the whole CPDN team can develop and test our ideas to become world leading experts on extreme weather events in a changing climate”.
