Facing Violence and War
Authors: Becker Eve-Marie
Published: July 2023

Mark 13 marks the transition from Jesus' public ministry in Galilee and Jerusalem to the passion events (Mark 14–15). Jesus' eschatological discourse is at the juncture of the Gospel narrative and is thus fundamental to the Markan interpretation of time and history. By discussing the reading paradigms of traumatology and empire criticism, this article seeks to make sense of Mark's "narrative agenda" from Mark 3:6 to chapter 15 in historical and historiographical terms. I shall ask: in which way does Mark – the creator of early Christian literary memory in a narrative sense – memorize, reflect, and construe contemporary history? And what significance do the topics of violence and war – crucial for Mark 13 – have in this context? In which form and for what purpose does Mark create Zeitgeschichtsschreibung? It will be argued that the way in which the earliest Gospel writer approaches contemporary history is multi-dimensional and manifold. Even if phenomena of sociopolitical crisis and trauma might stay on our list of possible "historical triggers" which illuminate the composition process of the Markan Gospel and Mark's view on contemporary history, the interpretive framework should be broadened.

Abstract. Dimethyl sulfide (DMS), a gas produced by phytoplankton, is the largest
source of atmospheric sulfur over marine areas. DMS undergoes oxidation in
the atmosphere to form a range of oxidation products, out of which sulfuric
acid (SA) is well known for participating in the formation and growth of
atmospheric aerosol particles, and the same is also presumed for
methanesulfonic acid (MSA). Recently, a new oxidation product of DMS,
hydroperoxymethyl thioformate (HPMTF), was discovered and later also measured
in the atmosphere. Little is still known about the fate of this compound and
its potential to partition into the particle phase. In this study, we present
a full year (2020) of concurrent gas- and particle-phase observations of
HPMTF, MSA, SA and other DMS oxidation products at the Zeppelin Observatory
(Ny-Ålesund, Svalbard) located in the Arctic. This is the first time
HPMTF has been measured in Svalbard and attempted to be observed in
atmospheric particles. The results show that gas-phase HPMTF concentrations
largely follow the same pattern as MSA during the sunlit months
(April–September), indicating production of HPMTF around Svalbard. However,
HPMTF was not observed in significant amounts in the particle phase, despite
high gas-phase levels. Particulate MSA and SA were observed during the
sunlit months, although the highest median levels of particulate SA were
measured in February, coinciding with the highest gaseous SA levels with
assumed anthropogenic origin. We further show that gas- and particle-phase
MSA and SA are coupled in May–July, whereas HPMTF lies outside of this
correlation due to the low particulate concentrations. These results provide
more information about the relationship between HPMTF and other DMS
oxidation products, in a part of the world where these have not been explored
yet, and about HPMTF's ability to contribute to particle growth and cloud
formation.

Abstract. Alongside a transition from steerable and centralized traditional electricity generation to intermittent and more decentralized renewable electricity generation from solar panels and wind turbines, Dutch energy transition scenarios project a widespread deployment of heat pumps and electric vehicles towards 2050. While clearly contributing to the decarbonization of the Dutch energy system, these developments impose challenges regarding electricity supply-demand mismatch and grid congestion. Spatially resolved electricity demand and supply profiles are required to gain a better insight into where and when such problems are likely to occur within the different scenarios. The present paper focuses on Dutch solar energy supply and features the construction of geodatabases of scenario-specific, spatially resolved electricity generation profiles for building, land and water-bound PV. Country-level PV capacities are geographically distributed based on spatial variance in roof PV potential and availability of suitable land and water use areas. Corresponding electricity generation profiles are constructed using historical meteorological measurements, a diffuse fraction model and a anisotropic transposition model. Empirically found performance ratio profiles are applied to account for a multitude of performance loss factors, including shading, dust and inverter efficiency. In 2050, building-bound capacity is projected to show only limited overlap with both land-bound and water-bound PV capacity. On the other hand, regions with considerable water-bound PV capacity also tend to show considerable land-bound PV capacity. Compared to the present-day situation, yearly country-level PV electricity generation is projected to be a factor 18.5, 15.7, or 7.7 higher in 2050 when respectively following the Regional, National or International Steering scenarios.

Abstract. The Earth Explorer mission Earth Clouds, Aerosols and Radiation Explorer (EarthCARE) will not only provide profile information on aerosols but also deliver a horizontal context to it through measurements by its Multi-Spectral Imager (MSI). The columnar aerosol product relying on these passive signals is called M-AOT (MSI-Aerosol Optical Thickness). Its main parameters are aerosol optical thickness (AOT) at 670 nm over ocean and valid land pixels and at 865 nm over ocean. Here, the algorithm and assumptions behind it are presented. Further, first examples of product parameters are given based on applying the algorithm to simulated EarthCARE test data and Moderate Resolution Imaging Spectroradiometer (MODIS) Level-1 data. Comparisons to input fields used for simulations, to the official MODIS aerosol product, to AErosol RObotic NETwork (AERONET) and to Maritime Aerosol Network (MAN) show an overall reasonable agreement. Over ocean, correlations are 0.98 (simulated scenes), 0.96 (compared to MYD04) and 0.9 (compared to MAN). Over land, correlations are 0.62 (simulated scenes), 0.87 (compared to MYD04) and 0.77 (compared to AERONET). A concluding discussion will focus on future improvements that are necessary and envisioned to enhance the product.
The weather diary of Georg Christoph Eimmart for Nuremberg, 1695–1704
Authors: Brönnimann Stefan
Published: July 2023

Abstract. Data from weather diaries have long been used to reconstruct past climate.
However, they could also be used to reconstruct past weather. Weather
reconstructions could help us to better understand the mechanisms behind, and
impacts of, climatic changes. However, reconstructing the day-to-day weather
requires many diaries from different regions covering the same period,
ideally combined with instrumental measurements. In this paper, I describe
the weather diary of Georg Christoph Eimmart from Nuremberg, covering the
period 1695 to 1704, which was particularly cold in Europe. The diary was
imaged from the Russian National Library in St. Petersburg and then
digitized. It contains twice-daily weather conditions in symbolic form, wind
direction details, and information on precipitation and temperature in text form.
Symbols changed during the first 2 years, after which a much-reduced (and
stable) set of symbols was used. Re-coding all days according to the later
set of symbols, I find no signs of inconsistency over time in symbols, wind
direction, and precipitation information extracted from the text.
Comparisons with other sources confirm the day-to-day weather information in
the diary. For instance, the wind direction in Nuremberg agrees with the
daily pressure gradient between Jena and Paris. Three case studies further
confirm the meteorological reliability of the information. This is shown on
behalf of an 8 d sequence of stormy weather in 1702, a study of the
severe winter of 1697/98, and a study of the summer of 1695, which was cold and wet,
possibly related to tropical volcanic eruptions. The examples underline the
consistency of the weather diary with other information and suggest that
weather reconstructions as far back as the late 17th century might
become possible. However, the spatial information is limited, and any
approach arguably needs to make good use of the temporal sequence of
information.
Implications for the Resilience of Modern Coastal Systems Derived from Mesoscale Barrier Dynamics at Fire Island, New York

Abstract. Understanding coastal barrier response to future changes in sea-level rise rate, sediment availability, and storm intensity/frequency is essential for coastal planning, including socioeconomic and ecological management. Identifying drivers of past changes in barrier morphology, as well as barrier sensitivity to these forces, is necessary to accomplish this. Using remote-sensing, field, and laboratory analyses, we reconstruct the mesoscale (decades-centuries) evolution of central Fire Island, a portion of a 50-kilometer barrier island fronting Long Island, New York, USA. We find that the configuration of the modern beach and foredune at Fire Island is radically different from the system’s relict morphostratigraphy. Central Fire Island is comprised of at least three formerly inlet-divided rotational barriers with distinct subaerial beach and dune-ridge systems that were active prior to the mid-19th century. Varying morphologic states reflected in the relict barriers (e.g., progradational, transgressive) contrast with the modern barrier, which is dominated by a tall and nearly continuous foredune and is relatively static except for erosion and drowning of fringing marsh. We suggest this state shift indicates a transition from a regime dominated by inlet-mediated gradients in alongshore sediment availability to one where human impacts exerted greater influence on island evolution from the late 19th century onward. The retention of some ‘geomorphic capital’ in Fire Island’s relict subaerial features combined with its static nature renders the barrier increasingly susceptible to narrowing and passive submergence. This may lead to an abrupt geomorphic state shift in the future, a veiled vulnerability that may also exist in other stabilized barriers.

Abstract. Atmospheric processes and climate are closely linked to the carbon cycle in the Amazon region as a consequence of the strong biosphere-atmosphere coupling. The radiative effects of aerosols and clouds are still unknown for a wide variety of species and types of vegetation present in Amazonian biomes. This study examines the effects of atmospheric aerosols on solar radiation and their effects on Net Ecosystem Exchange (NEE) in an area of semideciduous tropical forest in the North of Mato Grosso State. Our results show a reduction in the NEE with a decrease in incident solar radiation of ≈ 40 % and relative irradiance between 1.10–0.67. However, an average increase of 35–70 % in NEE was observed when pollution levels (Aerosol Optical Depth) were above ≈ 1.25. The increase NEE was attributed to the increase of up to 60 % in the diffuse fraction of Photosynthetically Active Radiation. These results were mainly attributable to the biomass burning organic aerosols from fires. Important influences on temperature and relative humidity of the air, induced by the interaction between solar radiation and high aerosol load in the observation area, were also noticed; an average cooling of ≈ 3.0 °C and 10 %, respectively. Given the long-distance transport of aerosols emitted by burning biomass, significant changes in CO2 flux can occur over large areas of the Amazon, with important effects on the potential for CO2 absorption on ecosystems of semideciduous forests distributed in the region.
