Postdoctoral Fellow on bounding the Earth´s climate sensitivity
Ref. No. SU FV-4074-18
at the Department of Meteorology. Closing date: 21 January 2019.
At the Department of Meteorology at Stockholm University (MISU) we conduct research and education in an international environment within four main areas: Atmospheric physics, Dynamic meteorology, Physical oceanography and Chemical meteorology. In all these areas there is a strong focus on the climate and on processes important for the climate and its development. The department employs some 65 individuals, of which about 30 are scientists, 20 PhD students and 15 in the administration and the technical support. The department is part of the Bolin Centre for Climate Research (www.bolin.su.se) and together with three other departments at the university cover research of most of the important aspects of the climate system.

The Earth's temperature response to increasing CO2 is key to understanding our past changing climate and for projecting into the future. But unfortunately the strength of the response is not well constrained. The latest IPCC report states a likely range of 1.5 to 4.5 degrees equilibrium climate sensitivity (ECS) for a doubling of atmospheric CO2, but with an up to 10 percent likelihood of it being above 6 degrees. In particular the risks involved with Earth possibly having a high equilibrium climate sensitivity are concerning, both scientifically as well as practically.
It is the purpose of the five-year highECS European Research Council (ERC) Consolidator Grant project to rein in the upper bound on Earth's climate sensitivity. The project has a strong focus on what Earth's past can teach us, and seeks to understand what models might be missing, with an overarching goal of a physical reconciliation of the evidence. The project is envisioned, but not bound, to proceed along three lines:
1) Confronting ideas of high ECS with the past. Here a state-of the art climate model is tailored to exhibit various extreme cloud feedbacks, and then run into historical and pre-historical warm and cold climates, in part to test their validity, but with the ultimate goal to build confidence in emergent constraints of ECS. An important component here is the interpretation of proxies as evidence for past climates.
2) Time- and state-dependent feedbacks. Here we seek to build the physical foundation of how climate change feedback mechanisms may be different in warmer or colder climates, and we will strive to quantify how patterns of warming arising when the climate is out of equilibrium (such as currently is the case) may impact the radiation balance.
3) Missing or biased feedbacks. Climate models have strong positive tropical infrared feedbacks, however, they systematically underestimate the infrared emission response to space – as observed from satellites – related to natural variations in surface temperature. In this part we will test ideas of why that might be the case, and relate these short-term biases to the long-term climate feedbacks.
The proposed work can focus on one or more of these topics, or be supportive of the overall goal of the project. As tools fellows have options to use the for example the MPI-ESM1.2 climate model and the ICON global cloud resolving model running on Swedish supercomputers, but are certainly not bound to using these.
Here we are looking for one or two postdoctoral fellows to work within the highECS project team. Candidates are expected to conduct research which contributes to the project objective as described above.
Postdoctoral positions are appointed primarily for purposes of research. Applicants are expected to hold a Swedish doctoral degree or an equivalent degree from another country.
The degree should have been completed no more than three years before the deadline for applications. An older degree may be acceptable under special circumstances, which may involve sick leave, parental leave, clinical attachment, elected positions in trade unions, or similar.
Selection criteria will be on scientific merit and skills relevant to the project.
Terms of employment
The positions involves full-time employment for a maximum of two years, with the possibility of extension within the project. Starting date is preferentially in Winter or Spring 2019, or as per agreement.
Stockholm University strives to be a workplace free from discrimination and with equal opportunities for all.
