Scenarios, carbon budgets and temperature projections in the new IPCC WG1 AR6 reportTuesday, 10 August 2021 - 4:30pm to 5:30pm
Abstract: The Physical Science (Working Group 1) contribution to the IPCC’s Sixth Assessment Report will be released on the 10th August 2021. This first of two seminars will provide an overview of some key results in the IPCC report, presented by two authors that have been closely involved in this IPCC cycle. The seminar will cover the new scenarios that underpin future projections, historical warming updates, the question around how these scenarios compare to 1.5C warming, a comparison of when peak warming levels could be reached under the low mitigation scenarios, the impact of COVID, techniques to provide assessed future temperature projections based on multiple lines of evidence, the usefulness of providing projections against warming levels, remaining carbon budgets in comparison to the SR.5 report, as well as the importance of CO2 versus other gases, both in terms of past and future warming as well as in terms of so-called metrics that compare unit emissions of different GHGs. The second seminar (24th August) will provide more technical detail on two key aspects, i.e. assessed future warming levels and remaining carbon budgets.Speaker(s)Australian-German College in Melbourne
Malte’s research interests comprise probabilistic climate projections, carbon budgets and emulations of multiple climate system uncertainties. He is one of the Lead Authors for the IPCC Sixth Assessment Report on the physical climate science (WG1), and part of the Core Writing Team of the IPCC Synthesis Report. Malte has been the scientific advisor to the German Environmental Ministry, being part of the German negotiation team at international climate change negotiations for more than 10 years. In his scientific career, he received an Australian Research Council’s Future Fellowship Award to investigate Australia’s fair contribution towards a global mitigation effort. Malte is Associate Professor in Climate Science at the School of Geography, Earth and Atmospheric Sciences at the University of Melbourne.
Zebedee is an expert in reduced complexity climate model development. Alongside A/Prof Malte Meinshausen, he leads the Reduced Complexity Model Intercomparison Project (RCMIP), which performs standardised evaluation of reduced complexity climate models. He also led the development of a common resource for reduced complexity model calibration data based on ESM output (cmip6.science.unimelb.edu.au) and helped create the input greenhouse gas datasets for CMIP6’s future scenario experiments. Zebedee submitted his PhD at the Climate & Energy College within the University of Melbourne’s School of Geography, Earth and Atmospheric Sciences in May, and before that completed his undergraduate Masters course in Physics at St. John’s College, University of Oxford. Beyond his PhD, Zebedee contributed to Working Group 1 of the forthcoming IPCC Sixth Assessment Report, leading Cross-Chapter Box 7.1 and acting as a Contributing Author to Chapters 1, 4, 5, 6 and 7.
Potential and risks of hydrogen-based e-fuels in climate change mitigationTuesday, 27 July 2021 - 4:30pm to 5:30pm
Falko Ueckerdt starts with structuring the current hydrogen debate (in particular in Germany and the EU). Then he goes through key techno-economic aspects that determine the role of hydrogen-based e-fuels, particularly compared to a direct electrification. This includes green hydrogen electrolysis expansion (available quantities), energy efficiencies, climate mitigation effectiveness, as well as direct and abatement costs. Falko briefly discusses blue hydrogen and other options of bridging the low mid-term availability of green hydrogen. In his conclusions he argues that societies' hydrogen expectations should be focused on no-regret sectors. Broadly betting on (future) hydrogen, while neglecting available direct electrification technologies (and domestic renewable expansion), risks further fossil fuel dependence (new lock-ins).
Development of a Sea Ice Emulator: A Progress UpdateTuesday, 13 July 2021 - 4:00pm to 5:00pm
Arctic sea ice is a complex yet fundamental component of the Earth system, and is a sensitive indicator of global climatic changes. Since the satellite record began in 1979, the Arctic ocean has received increasing attention due to the rapid decline of sea ice coverage (Niederdrenk and Notz, 2018). This has raised concerns regarding the future state of Arctic sea ice and the subsequent implications of its continued decline. Both passive satellite observations and global climate models used in the sixth phase of the Coupled Model Intercomparison Project, unanimously show continued year-round reductions in Arctic sea ice throughout the 21st century. The prediction of unprecedented Arctic sea ice loss has led to the clear consensus that the continued rate of Arctic sea ice reduction will present far-reaching, severe implications to atmospheric and oceanic systems. However, the nature and scale of the response to Arctic sea-ice loss and the mechanisms involved remains uncertain. CMIP6 models currently produce a wide spread of sea ice area projections and fail to plausibly simulate sea-ice area evolution to changes in global mean surface temperature. This limitation is exacerbated through the computational expense of current models preventing numerous runs over multi-centennial timescales and scenarios. In this PhD confirmation seminar Siân Chilcott will discuss how a sea ice emulator can be used to gain a new understanding into the behavior of complex CMIP6 models; and how such a tool will provide insight into why model projections differ from observations and what the dominant drivers of sea ice loss are. This project aims to make sense of the wide spread of CMIP6 projections in order to produce a plausible set of sea ice area projections.Speaker(s)Australian-German Climate and Energy College University of Hamburg
Siân Chilcott is a joint PhD candidate at the University of Melbourne and the University of Hamburg, under the supervision of A/Prof Malte Meinshausen and A/Prof Dirk Notz. Siân completed an integrated masters (MSci) in Earth Sciences at University College London. During this time Siân carried out research at the UCL Centre for Polar Observation and Modelling (CPOM), here she developed an interest in Arctic sea ice and its role in the climate system.
