February 22 - 23, 2021, via Zoom

Organised by an interdisciplinary team of researchers at Stockholm University and KTH, we will bring together scientific and philosophical expertise with a range of short key-note talks by Andrew Gettelman, Gabi Hegerl, Ted Shepherd, Erica Thompson, Matt Brown, and Wendy Parker, followed by in-group discussions with a limited number of participants. The workshop will be on two consecutive half-days (15-18.30 CET, 14-17.30 GMT, 9-12.30 EST), agenda below.

VaChUM is an interdisciplinary research project at Stockholm involving Frida BenderPer Wikman Svahn, Karoliina Pulkkinen, and Sabine Undorf.

Per and Karoliina are philosophers based at the Royal Institute of Technology (KTH). Per is an expert in uncertainty and risk, interested amongst other things in philosophical aspects of worst-case scenarios, managing climate change risks, and ethical issues in adaptation to sea level rise and radiation risk management. Per is an expert in uncertainty and risk. Karoliina is working on values in science. In previous work, she has especially focussed on the role of values in the development of the periodic system of chemical elements.

Frida and Sabine are climate scientists at the Department of Meteorology at Stockholm University (MISU) and working on aerosol-cloud-climate interactions and how choices in how they are represented in global climate models translate into model-derived projection uncertainty. Frida is an expert in aerosol-cloud interactions and corresponding satellite data-climate model intercomparison, further involved in other interdisciplinary projects, and engaged in a range of outreach activities. Sabine has previously applied statistical methods to detect anthropogenically forced signals in observations and to constrain future projections, and analysed climate projections for adaptation purposes in cooperation with social scientists and stakeholders.

Together, the four think about values in climate modelling.

Please register here for the workshop, by February 1, 2021.

Note that registration is required for both days, but if you are interested in joining the discussion (day 2) in addition to the talks (day 1 and/or 2), please add a sentence motivating your interest by Feb 1 2021.

Confirmation of a space in the discussion will be emailed out in early February and links shortly before the workshop. An Final Agenda in pdf-format will also be provided at that time.

If you are finding this workshop advert after Feb 1 and are interested in attending the talks, please get in touch by email and we will try to enable that.
