Global carbon cycle
The newest assessment of the global carbon cycle from the Global Carbon Project can be found in the Global Carbon Budget 2025, for which I coordinated the component on CO2 emissions from land-use change.
In an article published in the journal One Earth I investigated how emissions from land use, land-use change, and forestry estimated by different datasets can be reconciled at the country-level (Schwingshackl et al., 2022). The article shows that the reconciliation is generally successful for various countries, and identifies potential reasons for remaining differences. I also contributed to a related study focusing on global estimates (Grassi et al., 2023).
Land use and land-use change
In a shared first-authored perspective in the journal Nature Reviews Earth & Environment, my colleague Wolfgang Obermeier and I investigated uncertainties and differences in CO2 fluxes from land-use change, and we identified promising improvements to lower uncertainties and make different estimates better comparable.
This blog post on Carbon Brief summarizes and discusses CO2 emissions from land-use change in six countries/regions with large emissions. It gives a comprehensible overview on the drivers of CO2 emissions from land-use change.
Heat stress
Urban areas are hotspots of heat stress due to the high population density in cities and the urban heat island effect. To analyze the future development of heat stress in European cities under climate change we used high-resolution simulations from regional climate models (EURO-CORDEX) and calculated different day-time and night-time heat indicators (Schwingshackl et al., 2024).
A group of bachelor students that I supervised in the project seminar Heat stress in cities developed a method that can be used to monitor the effectiveness of measures to mitigate urban heat islands based on Landsat satellite data. They published the results using the city of Stuttgart as a case study (Seeberg et al., 2022).
