Postdoc (m/f/d) in climate uncertainty and CDR interlinkage assessment using Earth system modelling and statistical analyses

Deadline: 17th July 2022

The research unit Marine Biogeochemistry of the research division Biogeochemical Modelling (GEOMAR Helmholtz Centre for Ocean Research Kiel) is offering a postdoc position starting on September 1st, 2022. The research will involve working as part of an interdisciplinary team where the scientist is expected to provide expertise on modelling CDR approaches. Initial work will involve usage of the newest version of an Earth system model of intermediate complexity (UVic ESCM) to perform a biogeochemical and physical parameter perturbation experiment for temperature stabilisation scenarios to assess the uncertainty space in these underexplored scenarios. Furthermore, the Postdoc will assess the impact of various CDR measures by explicitly including them in these simulations. Finally, the interlinkages (i.e., additionality and trade-offs) of CDR measures will be assessed using statistical analysis tools.


Postdoc (m/f/d) in assessment of climate forcing impact of CDR measures using IAM data and Earth system modelling

Deadline: 1st July 2022

The research unit Marine Biogeochemistry of the research division Biogeochemical Modelling (GEOMAR Helmholtz Centre for Ocean Research Kiel) is offering a postdoc position. The postdoc will utilise integrated assessment modelling data and newest literature findings of emerging Carbon Dioxide Removal (CDR) measures to conduct life cycle assessments of the complete forcing footprints of currently proposed CDR measures. The assessment includes greenhouse gas and aerosol emissions and other climate forcing impacts of CDR measures. Using this forcing data, the climate forcing footprints of the CDR measures are estimated using an Earth system model of intermediate complexity. Assessing the overall climate impact of CDR measures over time allows us to understand their overall efficacy and their ability to compensate other anthropogenic activities.


Koweek (2022): Expected Limits on the Potential for Carbon Dioxide Removal From Artificial Upwelling

David A. Koweek IN: Front. Mar. Sci., 29 June 2022,

This work examines the question: Can pumping of nutrient-rich water from the deep ocean to the surface draw down CO2? The modelling study concludes that artificial upwelling is probably not likely to drawdown much CO2, resulting in very small estimates of CDR potential. Moreover, additional production supported by bringing new nutrients to the surface is almost completely offset by the release of CO2 from deep ocean water.


Frontier facilitates carbon removal purchases


„Earlier this year, Stripe, Alphabet, Shopify, Meta, and McKinsey Sustainability launched Frontier, an advance market commitment to accelerate the development of carbon removal technologies. A few months later, after careful review from an advisory panel of 19 scientists and industry experts, Frontier has facilitated its first purchases—from AspiraDAC, Calcite-Origen, Lithos Carbon, RepAir, Travertine, and Living Carbon—on behalf of Stripe.“

Science – Seddon (2022): Harnessing the potential of nature-based solutions for mitigating and adapting to climate change

Nathalie Seddon IN: SCIENCE, 23 Jun 2022, Vol 376, Issue 6600, pp. 1410-1416; DOI: 10.1126/science.abn9668

This article gives an overview of recent research on the benefits and limits of nature-based solutions, including how they compare with technological approaches, and highlight critical areas for future research.


Jaschke and Biermann (2022): The policy discourse on negative emissions, land-based technologies, and the Global South

Gregor Jaschke and Frank Biermann IN: Global Environmental Change, Volume 75, July 2022, 102550,

This article analyzes the nascent policy discourse on negative emissions with a focus on land-based technologies (afforestation and reforestation, bioenergy with carbon capture and storage, biochar, soil carbon sequestration). The authors conclude that this policy discourse is largely centered in the Global North (mostly in the United States, the United Kingdom, and Germany), with only five organizations directly linked to the Global South. While the earlier policy discourse on negative emissions was linked to a more general “geoengineering” discourse, this link has loosened in the last years. Overall, in the documents that were studied, negative emissions technologies seem to become more accepted, and parts of the discourse shift towards deployment.
