Der vorliegende Beitrag geht der Frage nach, ob die schweizerische Demokratie bereits ab der Bundesstaatsgründung im Jahr 1848 eine ausgeprägte Konsensusdemokratie war. Zur Beantwortung dieser Fragestellung bedient sich die Studie des Konzepts von Arend Lijphart (2012) mit der Unterscheidung von Mehrheits- und Konsensusdemokratie. Anhand von Literatur- und Dokumentenanalysen wurden Lijpharts Indikatoren für den schweizerischen Bundesstaat von 1848–1874 codiert. Die Ergebnisse zeigen, dass das politische System der neu gegründeten Schweiz auf Lijpharts Demokratiekarte insbesondere auf der horizontalen Machtteilungsdimension wie erwartet sehr nahe an der Position der USA zu liegen kommt.

We describe the recovery of three daily meteorological records for the southern Alps (Domodossola, Riva del Garda, and Rovereto), all starting in the second half of the nineteenth century. We use these new data, along with additional records, to study regional changes in the mean temperature and extreme indices of heat waves and cold spells frequency and duration over the period 1874–2015. The records are homogenized using subdaily cloud cover observations as a constraint for the statistical model, an approach that has never been applied before in the literature. A case study based on a record of parallel observations between a traditional meteorological window and a modern screen shows that the use of cloud cover can reduce the root-mean-square error of the homogenization by up to 30% in comparison to an unaided statistical correction. We find that mean temperature in the southern Alps has increased by 1.4°C per century over the analyzed period, with larger increases in daily minimum temperatures than maximum temperatures. The number of hot days in summer has more than tripled, and a similar increase is observed in duration of heat waves. Cold days in winter have dropped at a similar rate. These trends are mainly caused by climate change over the last few decades.

Herbert E Wright Jr was one of the foremost Quaternary scientists of the last century. He made wide ranging contributions to our understanding of the late-Quaternary of North and South America, Europe, Asia and Africa. This was based largely on reconstructing palaeoenvironments from lake sediments and included the important implications for glacial, vegetational, fire and climatic history, geoarchaeology and conservation. Many of his inter-disciplinary research projects involved fieldwork with his graduate students and co-workers from the University of Minnesota where he created and led the renowned Limnological Research Center. Perhaps his most outstanding contribution was as an instigator of the Co-operative Holocene Mapping Project (COHMAP). This triggered a paradigm shift in Holocene climatic research involving the comparison of climate-model simulations of past climates with palaeoclimatic data.
