Opis:
The site at Orłowo Cliff was used to analyse the stratigraphic position and palaeogeographic interpretations of the properties and depositional conditions of two basal tills from the Late Pleistocene. A multi-proxy approach involved lithofacies, petrographic analysis of the fine gravel fraction, analyses of indicator erratics and till fabric. TL dating of intra-moraine deposits was used to determine depositional time frames of tills. The sediment profile at Orłowo Cliff shows a distinct reduction in number of Pleistocene units. Obtained dating results suggest the presence of Middle and Late Pleistocene fluvial units. The main issue discussed is the stratigraphic position of the older till (Unit O-4). It can be assumed that this till was deposited probably during the Middle Weichselian (MIS4). At Orłowo Horn the till of Unit O-4 reveals incorporation of the erratic material derived from an older till in the surrounded area (according to petrographic composition – probably from MIS 8). The younger till (Unit O-6) was deposited in the Late Weichselian (MIS 2). Moreover, the till of Unit O-6 is characterised by a significant shift towards the south-west in terms of the erratic origin in Unit O-4.

Opis:
This paper outlines the symptoms of contemporary global warming, reviews its possible driving factors and presents some projections for future. Key among the symptoms are those related to temperature, with the increase in average global temperature since 1880 now reaching a value of 0.85°C. While warming has encompassed almost the whole world, the high latitudes have warmed more than the low, and maximum temperature has increased more than average temperature. Warming has been causing sea level rise, thanks to both the thermal expansion of warming water and the melting of ice on land. The other consequence of warming is a change in precipitation pattern, manifesting itself in higher precipitation in certain parts of the world (generally at low and high latitudes), but also lower precipitation in other parts (mainly the Tropics); as well as in changes in the intraannual course characterising precipitation (with more falling in winter and less in summer), and in the frequency and intensity of rainfall (more intense heavy-precipitation events and higher variability where the frequency of precipitation is concerned). Among the possible driving factors, the most important are those related to the increase of CO2 and mixing ratios of other greenhouse gases in the troposphere. Land-use changes and emissions of aerosols to the atmosphere also exert a major impact on temperature. These are mainly anthropogenic factors. While natural drivers also modulate the climate markedly, they tend to warm and cool the globe alternately, stepping up warming when they are in a warming phase, but slowing down or even offsetting warming during a cooling phase. Projections for the future are entirely dependent on socio-economic scenarios of future development. All the (economically) realistic scenarios point to a continuation of the warming trend, with a further intense sea-level rise and precipitation changes, albeit with the rate of change varying in line with the rate of increase in concentrations of the greenhouse gases. The realistic range of values for average rise in global temperature is between 2 and even 6 degrees Celsius.

Opis:
Remains of a vast Roman pottery production complex were found on the shore of the Plemići Bay (Općina Ražanac, Zadar county) in 2012, and confirmed by geophysical survey. Ground-penetrating radar measurements revealed outline of a rectangular building that finds analogies with Roman storehouses (horreum). The area occupied by remains of the Roman pottery workshop was covered by immense soil-debris flows. Three geological exposures located to the north of the remains of the Roman building were documented using lithological and malacological analysis, and magnetic susceptibility measurements. The profiles revealed at least three generations of slope sediments, formed in result ofintensive soil or debris flows in a dry climate, most probably in 5th c. AD. In the next, wet phase sediments were transported downslope and deposited on the Roman structures after 5th c. AD. Environmental conditions at Pelmići weresupply with paleoclimate evidence from the Adriatic region. At ca. 1.5 cal. BP lake levels in the eastern Adriatic area were drastically reduced, probably because of strong decrease in humidity, correlated with the so-called North Atlantic Bond event 3. The drought was followed by a humid episode, also attested at the Plemići archaeological site.

Opis:
The archaeological site Tell el-Retaba in north-eastern Egypt, about 35 km to the west of Ismailia city, is located in the middle of Wadi Tumilat, a shallow valley running from the Nile Delta to the Bitter Lakes, along which flows the Suez Canal. In ancient times the valley was a route between Egypt and Syro-Palestine, strongly fortified in the New Kingdom times (16th–11th century BC). Mud bricks were analyzed from two parts of the Wall 1 (core of grey-brown bricks and inner extension of green bricks) in a fortress which existed during the Ramesses II times. Grain-size composition of the studied bricks was almost identical in both parts of the wall, suggesting the same source material for a production of brick. However, significant differences were observed in physical and mechanical properties (uni-axial compressive strength) in both types of bricks. Bricks from the core had lower bulk density, higher porosity and soak faster, whereas their resistance parameters were much lower than those of the bricks from the inner extension. The reason for such large differences in brick properties was a technology of their production, particularly proportion of components, water volume added during brick formation or density degree. Brick preparation and in consequence, physical-mechanical properties had direct influence on preservation of defensive structures during environmental changes related to changes of groundwater and surface water levels or of precipitation. Ancient Egyptians responsible for construction works in mud brick structures of the fortress must have had good knowledge and experience. This could be observed particularly for the heaviest and most important construction element that is the defensive wall, founded on well-densified deposits. It was also testified by higher resistance of green bricks from the inner extensions, which probably originated slightly later and were intended to reinforce a weaker core built of grey-brown bricks.

Opis:
This study presents the results of a comprehensive geoarchaeological study implemented at an archeological site covering ca. 5 ha near the city of Csorna on the NW part of the Danube Plain, NW Hungary. The site itself exposed a complex fluvial system of an ice age creek with near bank and overbank areas (levee, point bar, back swamp). Spatial distribution of archeological features allowed for the interpretation of differential use of the fluvial landscape by different cultures. According to our data, the referred fluvial system must have emerged during the Late Glacial. At this time, creeks originating from hills to the SE followed a uniform NW trajectory. From the Holocene, small creeks were beheaded turning into inactive flood channels. It was the time when the gradual infilling of the floodplain started. Alternating layers of floodwater coarses and floodplain fines mark recurring floods at our site. These could have been correlated with cooler, wetter climatic phases of the North Atlantic, Western Europe and high stands in Central European lakes. Highest floods are recorded during the Late Bronze and Iron Ages besides the Neolithic. Pollen data enabled us to make inferences on the vegetation as well.

Opis:
The development of civilisation is linked inextricably with growing demand for electricity. Thus, the still-rapid increase in the level of utilisation of natural resources, including fossil fuels, leaves it more and more urgent that conventional energy technologies and the potential of the renewable energy sources be made subject to re-evaluation. It is estimated that last 200 years have seen use made of more than 50% of the available natural resources. Equally, if economic forecasts prove accurate, for at least several more decades, oil, natural gas and coal will go on being the basic primary energy sources. The alternative solution represented by nuclear energy remains a cause of considerable public concern, while the potential for use to be made of renewable energy sources is seen to be very much dependent on local environmental conditions. For this reason, it is necessary to emphasise the impact of research that focuses on the further sharpening-up of energy effi ciency, as well as actions aimed at increasing society’s awareness of the relevant issues. The history of recent centuries has shown that rapid economic and social transformation followed on from the industrial and technological revolutions, which is to say revolutions made possible by the development of power-supply technologies. While the 19th century was “the age of steam” or of coal, and the 20th century the era of oil and gas, the question now concerns the name that will at some point come to be associated with the 21st century. In this paper, the subjects of discussion are primary energy consumption and energy resources, though three international projects on the global scale are also presented, i.e. ITER, Hydrates and DESERTEC. These projects demonstrate new scientifi c and technical possibilities, though it is unlikely that commercialisation would prove feasible before 2050. Research should thus be focused on raising energy effi ciency. The development of high-effi ciency technologies that reinforce energy security is presented, with it being assumed that these new high-efficiency technologies are capable of being applied globally in the near future.

It is rotational movement of the Earth that decides on the climatic zonation of natural resources, as modifi ed by the positions of the continents and oceans and the irregular spread of fossil fuels. Intensive human activity poses threats to the development of natural geoecosystems. The last century also brought growing civilizational threats to the environment on the global, regional and local scales. The author characterise the prospects in regard to global changes, and discuss the solutions needing to be pursued if human geoecosystems are to be protected (through management and education).

This article presents religion’s potential where the promotion and implementation of the concept of sustainable development are concerned. First inspired by Lynn White in the 1960s, discussion on religion’s role in the ecological crisis now allows for an honest assessment of the ecological potential of various religious traditions and their contribution to the building of a sustainable world. This article on the one hand points to the religious inspirations behind the concept of sustainable development, and on the other highlights the joint action of representatives of religion and science in the name of sustainable development, as well as the involvement of religions in the concept’s implementation.

Opis:
An overview of systematic observations of the trace-gas composition of the atmosphere over southern Poland is presented, against the background of data available for other greenhouse gas (GHG) monitoring stations in Europe. The results of GHG monitoring for three major greenhouse gases (CO2, CH4, N2O) are discussed. Measurements were performed at two locations of contrasting characteristics, i.e. (i) the high-altitude mountain station of Kasprowy Wierch in the High Tatras, representing atmospheric conditions relatively free of local infl uences, and (ii) an urban station located in the Krakow agglomeration. The GHG data available for the Kasprowy Wierch station were compared with relevant data available for two marine reference stations (Mace Head, Ireland and Terceira Island, Azores), and two continental stations (Hohenpeissenberg, Germany and Pallas-Sammaltunturi, Finland). The growth rates for the CO2 mole fraction recorded at these fi ve stations reveal only small temporal changes that almost coincide, leading to a quasi-linear increase of the CO2 mixing ratio over the European continent over the past 20 years. While N2O observations also reveal a steady increase over this time period, the mole fraction accounted for by CH4 is increasing again, after a period of stagnation in the years 2001–2007. The impact of continental sources of CH4 and N2O is seen clearly in the Kasprowy Wierch records. The mean departure between the CH4 mixing ratios recorded at Kasprowy Wierch and at the marine reference stations in the period 1994–2014 is of 27.3 ppb, and stems from continental emissions of this gas originating mainly from anthropogenic activities (leaking natural-gas distribution networks, landfi lls and livestock). For N2O, a departure of 1 ppb was observed for the period 2009–2014. Comparison of quasi-continuous measurements of CO2, CH4 and N2O mixing ratios made in the urban atmosphere of Krakow and at the regional reference site Kasprowy Wierch (located approximately 100 km away), allows for a deeper insight into the mechanisms controlling daily variations in atmospheric mixing ratios of these gases at the two sites. The development of a nocturnal inversion layer in the atmosphere above the city leads to local enhancements of CO2, CH4 and N2O mole fractions in the Krakow atmosphere during the night hours, with these exceeding the baseline level signifi cantly.

Opis:
The purpose of this article is to identify and assess environmental risks that may have the greatest impact on the future of humanity. They were divided into two basic groups, i.e. for natural processes and resources. In addition, climate change is described as different group. The authors decided, that a holistic approach to this issue is more desirable than dividing it into two above-mentioned groups. The comparison of various threats was possible due to the application of identical assessment criteria, such as: the harmfulness, rate of spread, scope and moment of occurrence of a given group of threats. Each of the listed criteria has been evaluated on a fi ve-point scale, where 1 has the smallest and 5 the largest impact force. The obtained results show the leading importance of natural processes in maintaining the existing Earth system. In addition, the authors point to a greater risk of problems related to renewable resources than non-renewable one. As a result, it can be assumed that the current degradation of natural processes and excessive use of resources is likely to lead to the risk of global disasters.
