The paper deals with the growing threat of erosion to the south Baltic coast, caused by the intensification of a wind-induced wave climate and sea level rise, which is expected to continue until 2100 as a result of climate change. In the analysis, a deep-water wave prognostic point is located about 13 km north-east of the Hel Peninsula, situated in the NW part of the Gulf of Gdańsk. The study comprises the analyses of wind velocity, storm surge, wave height, wave set-up and wave run-up. A significant predicted increase in wave heights during extreme storms, compared with the wave climate reconstructed for 1958–2001, combined with anticipated higher storm surges, is expected to result in a lower resilience of the sea shore to erosion and flooding. Although nourishment operations conducted along the open sea shore of the Hel Peninsula have proved efficient and successful, nourishment needs will have to be adequately recalculated in future to ensure sufficient protection of this coastal segment.

<p>The contemporary morphogenetic system of the South Baltic Sea is clearly changing, both in the annual and long-term weather cycle. Morphogenetic seasons are subject to change, both in terms of duration and types of morphogenetic processes and related forms of relief. The duration of the late-autumn and early-spring season is clearly increasing, which is associated with the occurring climate change and related hydrometeorological conditions. All this means that the morphodynamic types of the South Baltic coast are subject to change, the nature of which is conditioned by geological structure, relief, land cover and, hydrometeorological conditions. Undoubted individuality of the geo-diversity of the South Baltic coast in Poland are postglacial cliff coasts (50 km long).</p><p>Systematic geomorphological mapping of cliff coasts carried out since 1975 which have recently been supported by GIS methods, allow the recognition of cliff coast development mechanisms, emerging landforms and associated morphodynamic types of the South Baltic coast.</p><p>Based on repetitive geomorphological mappings, the following morphodynamic types of the South Baltic cliffs can be distinguished: landslide-type, rock fall-type, talus-type, slump-type and flow-type.</p><p>The basis for the typology of morphodynamic types of cliff coasts was the dominant types of relief forms, including lithology, exposure, land cover and hydrometeorological conditions. It can be unequivocally assumed that the morphodynamic types of the cliff coast is a good indicator feature of monitored morphogenetic systems and their space-time variability.</p><p>The effect of the observed climate change is the increasing frequency of storm surges that initiate denudation processes of an extreme nature. Another consequence of the observed climate changes is the increasing variability of morphodynamic types of the South Baltic cliff coast in the analyzed morphogenetic seasons with a greater share of landslide and rock fall-types.</p>

The subject of this publication is to determine what environmental and climatic factors can significantly affect the value of real estate. As a research object, there was chosen area surrounding the Gulf of Gdansk, which, like the entire coast, is attractive for investment and constitutes an interesting object as a space with a special focus on tourism, including short-term rental. Progressing climate change is particularly affecting this sector. It is safe to assume that unfavorable environmental conditions can significantly change the attractiveness of this area. Therefore, the research hypothesis about the correlation between climate aspects distinguishing the coastal belt and the distribution of real estate prices in the selected area has been verified. The area of the Gulf of Gdansk Coast and the technical and protective belt were analyzed. The weather situation on the coast is different from that prevailing in the rest of the country. There are strong and gusty winds, local floods, but at the same time a natural landscape, proximity to the sea and clean, iodized air. Other possible climatic factors have also been tracked, i.e. temperature, sea level and possible changes that may occur over the next years. The analyzes were based on the data of the KLIMAT project entitled "The impact of climate change on the environment, economy and society", and the Government Project KLIMADA and SPA analyzes. An in-depth analysis of the problem of combining planning documents for the maritime sector influencing the Study of Spatial Development of Polish Marine Areas with Local Spatial Management Plans, introduced Flood Risk Maps and Flood Risk Maps was also conducted.

In the Vistula Lagoon, storm surges are induced by variable sea levels in the Gulf of Gdańsk and wind action. The rising of the water level in the southern part of the basin, exceeding 1.0 m above mean sea level, can be dangerous for the lowland area of Żuławy Elbląskie, causing the inundation of the polders adjacent to the lagoon. One of the potential possibilities to limit the flood risk is to decrease the water level in the lagoon during strong storm surges by opening an artificial canal to join the lagoon with the Gulf of Gdańsk. The decision to build a new strait in the Vistula Spit was made in 2017. In order to analyze the impact of the artificial connection between the sea and the lagoon during periods of high water stages in the southern part the lagoon, mathematical modelling of the hydrodynamics of the Vistula Lagoon is required. This paper presents the shallow water equations (SWEs) model adapted to simulate storm surges driven by the wind and sea tides, and the numerical results obtained for the present (without the new strait) and future (with the new strait) configuration of the Vistula Lagoon.

Anticipated acceleration of sea level rise in combination with expected higher set-up of storm surges will require strengthening of coastal protection structures. Dykes e. g. must then be heightened according to the existing design rules taking only hydrodynamical loads into consideration. Alternatively the development of new design rules taking both hydrodynamical loads and the strength of the available soil for the construction of a dyke might allow the explo-ration of up to now undetected safety margins. In order to explore these possibilities the German Coastal Engineering Research Council has provided the funds for a research project targeting these aims. First results of this project are presented in this paper on the background of achieved improvements for the determination of design wave run-up on coastal and estuarine sea dykes.

Holocene diatom biostratigraphy of the SW Gulf of Gdańsk, Southern Baltic Sea (part III)The palaeoenvironmental changes of the south-western part of the Gulf of Gdańsk during the last 8,000 years, with reference to the stages of the Baltic Sea, were reconstructed. Diatom analyses of two cores taken from the shallower and deeper parts of the basin enabled the conclusion to be drawn that the microflora studied developed in the three Baltic phases: Mastogloia, Littorina and Post-Littorina. Moreover, the so-called anthropogenic assemblage was observed in subbottom sediments of the study area.

Much of Buster Keaton’s slapstick comedy revolves around his elaborate outdoor sets and the crafty weather design that destroys them. In contrast to D. W. Griffith, who insisted on filming in naturally occurring weather, and the Hollywood norm of fabricating weather in the controlled space of the studio, Keaton opted to simulate weather on location. His elaborately choreographed gags with their storm surges and collapsing buildings required precise control of manufactured rain and wind, along with detailed knowledge of the weather conditions and climatological norms on site. Steamboat Bill, Jr. (1928) is one of many examples of Keaton’s weather design in which characters find themselves victims of elements that are clearly produced by the off-screen director. Keaton’s weather design finds parallels in World War I strategies of creating microclimates of death (using poison gas) as theorized by Peter Sloterdijk.


Climate justice requires sharing the burdens and benefits of climate change and its resolution equitably and fairly. It brings together justice between generations and justice within generations. The United Nations Sustainable Development Goals summit in September 2015, and the Conference of Parties to the Framework Convention on Climate Change in Paris in December 2015, brought climate justice center stage in global discussions. In the run up to Paris, Mary Robinson, former president of Ireland and the UN Secretary General’s Special Envoy for Climate Change, instituted the Climate Justice Dialogue. The editors of this volume, an economist and a philosopher, served on the High Level Advisory Committee of the Climate Justice Dialogue. They noted the overlap and mutual enforcement between the economic and philosophical discourses on climate justice. But they also noted the great need for these strands to come together to support the public and policy discourse. This volume is the result.
