Glacier-Atmosphere Interactions and Feedbacks in High-Mountain Regions - A Review
(2025)ESS Open ArchiveMountain glaciers are among the most vulnerable natural systems to climate change. However, their interactions with the atmosphere are complex and not fully understood. These interactions can trigger rapid adjustments and climate feedbacks that either amplify or attenuate atmospheric signals, influencing both glacier response and large-scale atmospheric circulation. Observing this functional coupling in nature is challenging because the ...Working Paper -
Micro-Meteorological Impact of Glacier Retreat and Proglacial Lake Temperature in Western Norway
(2024)ESS Open ArchiveGlaciers are retreating worldwide, yet, little is known about the influence of these changes on local weather and climate in glacial landscapes. Changes in glacier extent and proglacial lakes alter the thermodynamic forcing in glacier-lake-valley systems that may be of similar or greater importance for future microclimate than direct effects of global warming. To study the impact of these changes, we combine the first set of high-density ...Working Paper -
KI in der Wärmepumpenberatung
(2024)Wärmepumpen sind in der Schweiz die aktuell meistverkaufte Wärmequelle und bereits in rund 20% der Gebäude installiert. Wärmepumpen reduzieren den Verbrauch fossiler Energieträger, erhöhen aber den Bedarf an elektrischer Energie. Entsprechend wichtig ist ein effizienter Betrieb der Geräte nicht nur auf dem Prüfstand, sondern auch in der Praxis – und dies auch noch viele Jahre nach der Installation. Für Installateure stellen die Auslegung ...Report -

The TAPIR framework: A new tool to assess climate and energy demonstration projects
(2025)Addressing the climate and energy crises is an urgent priority. As emissions rise and energy supplies become less secure, governments and industries seek new solutions that can be deployed quickly and at scale. Synthetic fuels stand out as promising substitutes for fossil fuels that need minimal infrastructure changes and solve storage issues often raised by intermittent energy sources. However, their current production levels fall far ...Report -
Co-investment with Payoff Sharing Benefit Operators and Users in Network Design
(2024)arXivNetwork-based complex systems are inherently interconnected, with the design and performance of subnetworks being interdependent. However, the decisions of self-interested operators may lead to suboptimal outcomes for users. In this paper, we consider the question of what cooperative mechanisms can benefit both operators and users simultaneously. We address this question in a game theoretical setting, integrating both non-cooperative and ...Working Paper -
“One Person, One Vote”: The Effect of Direct Elections on U.S. Senators
(2025)Center for Law & Economics Working Paper SeriesThe 17th Amendment to the U.S. Constitution, ratified in 1913, introduced direct elections for the U.S. Senate, substantially democratizing the existing system of indirect selection by U.S. state legislatures. This paper analyzes the impacts of this reform on measures of each senator’s policy priorities constructed from the texts of their floor speeches and records of roll call votes. Using a difference-in-differences strategy comparing ...Working Paper
