His interdisciplinary research aims to inform evidence-based climate policy. The focus will be on the scientific evaluation of international climate agreements, identifying and responding to major knowledge gaps for effective and resilient climate policy, and developing new concepts that would bridge the gap between the social and physical sciences.

Agricultural risk assessment of climate change in the 21st century in a global comparison of Gridded Crop model. Proc. Natl Acad. Sci. United States 111, 3268-3273 (2013). The origin of the 1.5oC Paris Agreement stems from the concern of vulnerable countries about the negative consequences of a warming of 2oC. In 2014, the UNFCCC established a process to determine whether Cancun`s long-term goal of keeping warming below 2 degrees Celsius is sufficient to avoid dangerous climate change and to consider « strengthening the long-term global goal based on the best available scientific knowledge, including an average global temperature increase of 1.5 degrees Celsius. » This process ended in 2015 with the final report of its scientific arm (Structured Expert Dialogue), which concluded that the use of the global warming limit of 2oC as a « protection barrier » was not safe and that governments should instead aim for 1.5 degrees Celsius. It was found that the 2oC limit was not in line with the convention`s ultimate goal of « preventing dangerous anthropogenic intervention in the climate system. » This was an important contribution to the ongoing negotiations on the Paris Agreement at the time and ultimately led to the long-term goal of the Paris Agreement on temperature in Article 2.1, as described above.
