Late-Holocene
Early studies on the evolution of glaciers argue that the warm Early Holocene transitioned into a Late-Holocene Neoglacial, with numerous glacial advances due to decreasing solar forcing in the boreal summer. The assumption of decreasing temperatures based on the glacier studies was supported by several proxy-based reconstructions as well as by simulations. Under the keyword “Holocene temperature conundrum” this fact is questioned. In particular,…
European summer temperatures since Roman times
The spatial context is criticalwhen assessing present-day climate anomalies, attributing them to potential forcings and making statements regarding their frequency and severity in a long-term perspective. Recent international initiatives have expanded the number of high-quality proxy-records and developed new statistical reconstruction methods. These advances allow more rigorous regional past temperature reconstructions and, in turn, the possibil…
Implications arising from models of solar irradiance
Models of solar irradiance have been revised recently, leading to the current view that previous estimates of maximum total solar irradiance (TSI) in the 18th and 19th centuries were too low and should be adjusted upwards to be comparable with values in the 20th century. This adjustment is small (~0.03%) but implies a greater amplitude of irradiance change over recent centuries. This has no bearing on our concept of a Medieval Quiet Period
The Medieval Quiet Period
For several centuries in early Medieval times the climate system was relatively unperturbed by natural forcing factors, resulting in a unique period of climate stability. We argue that this represents a reference state for the Common Era, well before anthropogenic forcing became the dominant driver of the climate system
Continental-scale temperature variability during the past two millennia
Topoclimatological case-study of Alpine pastures near the Albula Pass in the eastern Swiss Alps
Alpine grasslands are an important source of fodder for the cattle of Alpine farmers. Only during the short summer season can these pastures be used for grazing. With the anticipated climate change, it is likely that plant production – and thus the fodder basis for the cattle – will be influenced. Investigating the dependence of biomass production on topoclimatic factors will allow us to better understand how anticipated climate change may influe…

Historical Climatology In Europe – The State Of The Art
European Seasonal and Annual Temperature Variability, Trends, and Extremes Since 1500
Multiproxy reconstructions of monthly and seasonal surface temperature fields for Europe back to 1500 show that the late 20th- and early 21st-century European climate is very likely (>95% confidence level) warmer than that of any time during the past 500 years. This agrees with findings for the entire Northern Hemisphere. European winter average temperatures during the period 1500 to 1900 were reduced by ∼0.5°C (0.25°C for annual mean temperature…
Dynamic and socioeconomic aspects of historical floods in Central Europe

Alpine Landscapes in New Zealand and Europe
Based on inventories of similarities and differences, a comparative approach to high mountains can yield surprising insights that highlight which aspects are unique in both cases and make “old things look new.” Insights are determined by the parameters of comparison. In this issue, the raw geographical elements of both high mountain areas have been the points of departure of the articles in the Development as well as the Research sections. Both h…
Interannual to century scale climate variability in the European Alps
Die Klimavariabilitat im europaischen Alpenraum auf der Zeitskala von Jahren bis Jahrhunderten Neue Zeitreihen von Proxydaten und friihen Instrumentenmessungen aus den Alpen erlauben eine prazisere Interpretation der Klimavariabilitat sowie der dahinter verborgenen Prozesse. Die Studie zeigt, daB wahrend Phasen mit unterschiedlichen Antriebscharakteristiken (forcings) des Klimasystems spezifische Temperatur- und Niederschlagsanomalien auftreten. …
Low frequency variability of atmospheric circulation over Europe between 1785 and 1994
A decadal analysis of monthly sea level pressure fields over Europe and the adjacent North Atlantic with a correlation-based classification scheme results in 12 classes. These classes show a high variability in the frequencies of their occurrence and also in the combination between the different classes. The range of the frequency changes from one decade to another can differ up to a factor 2. The class 1 high index situation with high positive v…
Das Ausbreitungsklima der Innerschweiz
The aim of this study is to determine the spatiotemporal structure of the dispersion climate over Central Switzerland. For that reason the investigations have been divided into two parts. The first part deals with the analysis ofthe temperature stratification which is an important indicator of the vertical diffusion. It was carried out by using IR satellite data as well as temperature measurements and fog observations. The second part is concemed…
Nebelkarten der Schweiz
The analysis of fog distribution over Switzerland consists of two different studies: The first deals with the spatial determination of fog frequencies and fog types for the early morning. It was realized by using the daily observations of 320 stations. This point by point information was spatially interpolated with the aid ofthe information (mean fog cover frequency) of 94 typical fog distributions detected from NOAA satellite data. The derived f…
