    Opis:
    In the late 20th century, warming on the Antarctic Peninsula was most pronounced compared to other parts of Antarctica. However, air temperature showed a significant variability, which has become especially evident in recent decades. Thus, the investigation of air temperature trends on the Antarctic Peninsula is important. This study examines the extreme air temperature at the Ukrainian Antarctic Akademik Vernadsky station, located on Galindez Island, Argentine Islands Archipelago, near the Antarctic Peninsula. For 1951 to 2020, based on the daily air temperature data, the temporal trends of extreme air temperature were analyzed, using 11 extreme temperature indices. Based on linear trend analysis and the Mann-Kendall trend test, the TXn, TNn, TN90p, and TN90p indices showed an upward trend, whereas theFD0, ID0, TN10p, TX10p, and DTR indices showed a downward trend. Among them, annually, FD0, ID0, and TN10p significantly decreased by –0.427 days, –0.452 days, and -0.465%, respectively, whereas TXn and TNn increased by 0.164℃ and 0.201℃, respectively. The indices TXx and TNn showed no statistically significant trends. The average annual difference between TX and TN (index DTR) showed a nonsignificant decreasing trend at –0.029℃ year-1 . Thus, for the period of 1951-2020, the Ukrainian Antarctic Akademik Vernadsky station was subjected to warming.

    Opis:
    Extreme rainfall is one of the environmental hazards with disastrous effects on the human environment. Water resources management is very vulnerable to any changes in rainfall intensities. A spatiotemporal analysis is essential for study the impact of climate change and variability on extreme rainfall. In this study, daily rainfall data for 36 meteorological stations in Iraq during 1981–2017 were used to investigate the spatiotemporal pattern of 10 extreme rainfall indices using RClimDex package. These indices were classified into two categories: rainfall total (PRCPTOT, SDII, R95p, R99p, RX1day, and RX5day) and rainfall days (CDD, CWD, R10, and R20). Depending on the mean annual precipitation data, the study area was divided into three climatic zones to examine the time series features of those 10 indices. Results showed a tendency to increase in precipitation toward the northwestern part of Iraq, and more than 70% of stations achieved a positive trend for most indices. The most frequent negative trend appeared in eight stations distributed in the western and southern parts of Iraq, namely (Heet, Haditha, Anah, Rutba, Qaim, Nukheb, Najaf, and Fao). A significant positive trend appeared obviously in PRCPTOT and R95p with a rate of 0.1–4.6 and 0.5–2.7 mm per year, respectively. Additionally, the least trend increasing appeared in all precipitation days indices specifically in R10 and R20. Time series analyses revealed a positive trend in all regions under study, except SDII in the southern region. The most significant rate of change was noticed in regions one and two (northern and middle parts of Iraq), particularly for PRCPTOT and R95p 3.26 and 2.45 mm per day, respectively. Only the northern and eastern regions of Iraq experienced a high probability of significant extreme rainfall.

    Opis:
    Climate change is a major threat to mangrove ecosystems worldwide but particularly those in arid regions that exist near the limit of tolerance to extremes in temperature, precipitation, and salinity. Here we examine Persian Gulf arid mangrove ecosystems from the Nayband and Mond Protected Area in the south-west region of Iran to determine the ability of tidal mangrove forests to respond to rapid urban and industrial development, sea-level rise (SLR), and temperature and precipitation changes. Sea level has been rising by approximately 4 mm yr−1 in this region and might be intensified by subsidence on the order of 1—2 mm yr−1 due to natural phenomena as well as anthropogenic activities associated with fluid extraction. We use remote sensing along with statistical analysis to effectively monitor mangrove area changes over 60 years and infer responses to past environmental trends. Our spatiotemporal analysis demonstrates expansion in some areas and reduction in others. NDVI (Normalized Difference Vegetation Index) results indicate that Nayband mangroves are healthy and expanded between the years of 1990 and 2002 which could be in response to rising temperatures and above-average precipitation. However, NDVI changes after 2002 demonstrate the mangrove health and area have decreased which could be in response to industrial and urban development that occurred immediately after 1997. The natural stresses in this extreme system are been exacerbated by climate change and anthropogenic pressures as such it is essential to develop ways to reduce vulnerability through strategic management planning.

    Opis:
    Prognozowane zmiany klimatu mogą przyczynić się w krajach europejskich do zwiększenia liczby katastrof, będących konsekwencją zwiększenia częstości występowania ekstremalnych zjawisk meteorologicznych. Celem niniejszego artykułu jest zwrócenie uwagi na zagrożenia i skutki socjoekonomiczne tych zjawisk. Przeanalizowano informacje zawarte w bazie danych EM-DAT, dotyczące katastrof naturalnych w latach 1994-2004. Na tej podstawie stwierdzono zwiększenie częstości występowania katastrofalnych w skutkach zdarzeń, będących konsekwencją ekstremalnych zjawisk meteorologicznych w analizowanym jedenastoletnim okresie. Najczęściej występującym zdarzeniem, powodującym największe straty materialne i ofiary w ludziach, są powodzie, szczególnie często zdarzające się we Francji. Najliczniejsze ofiary w ludziach w Europie są następstwem przede wszystkim ekstremalnych wartości temperatury i powodzi. Ze względu na prognozowane zwiększenie prawdopodobieństwa występowania ekstremalnych zjawisk meteorologicznych na naszym kontynencie należy się spodziewać, że coraz większa liczba jego mieszkańców będzie narażona na znalezienie się w zasięgu tego typu zjawisk.
    Forecasted climate changes will increase of natural disaster numbers in European countries that will be a consequence of increasing variability and frequency of weather-related events. The aim of this paper was to pay attention to threats and socio-economical effects caused by extreme weather events. Information gathered from EM-DAT database, related to natural disasters that took place in Europe in 1994-2004 years, were analyzed. The increasing frequency of weather-related disasters occurrence was observed in considered period. The most frequently occurring phenomena, which caused the most deaths and damage costs were floods, permanently observed in France. The most substantial number of mortal victims in Europe was also notice, besides floods, as the result of extreme temperatures. According to predicted global climate changes, the number of natural catastrophes in European countries will rise as a result of extreme events of weather increase. So, we should consider the fact that major number of habitats of our continent will be put in danger.

    The projected effect of climate change is the increase of both the frequency and intensity of extreme weather events. An attempt has been made to study the extremes in temperature over two regions of India i.e. North-East Region (NER) and West Coast Region (WCR). A detailed analysis indicated that in the NER, ten stations indicate increase in annual extreme minimum but significant at four stations. Post-monsoon season is very predominant where five stations show significant increase. In the WCR, all the stations indicate increasing trend in annual extreme maximum temperature significant at nine stations. Majority of the stations indicate significant increasing trend in all the seasons except monsoon season.

    Opis:
    Science-based knowledge about climate-related hazards is an inevitable part of the knowledge basis needed for many stakeholders’ decision-making. Despite continuous advances in climate science, much of this knowledge is perceived to be hardly accessible, understandable, or relevant to stakeholders. One relatively new field where these aspects may become evident is extreme weather event attribution. It has received much attention in science in recent years, but its potential usefulness to stakeholders has rarely been addressed in the literature so far. This study has therefore developed criteria for evaluating potential climate services from a stakeholder perspective, using the example of findings from extreme event attribution. This is illustrated in an empirical mixed-method study about decision-makers dealing with storm surge risks at the German Baltic Sea Coast and (re)insurance sector representatives. The study builds on interviews and workshops with potential users of extreme event attribution. It reveals that there are three main groups of criteria which matter most to the stakeholders in question: 1) trustworthiness, 2) context-sensitivity and decision-relevance, 3) clarity and comprehensibility. Having appropriate evaluation categories, as well as processes to identify stakeholder-specific criteria, will facilitate the inclusion of values, knowledge contexts, and interests. Many stakeholders emphasized that they need a trustworthy knowledge broker who provides decision-oriented information which is intuitively accessible, understandable, and in their mother tongue. Being independent, scientifically competent, and in a continuous dialogue with both scientists and stakeholders, established regional and sector-specific climate services can facilitate the fulfilment of these requirements. A stakeholder-oriented evaluation will thereby help to make climate services more useful to potential user groups – even if a product is not in use yet, as is the case for extreme event attribution products.

    Opis:
    Daily precipitation data from 40 stations are used to investigate the temporal variability of precipitation extremes in Estonia. The period covered is 1961–2008, characterized by a uniformity of observational practice. Precipitation extremes are quantified by yearly and seasonal values of two different parameters: daycount indices based on 95th and 99th percentile thresholds. Trend significance was assessed with the Mann-Kendall test. Results show that the frequency of both indices has increased. No significant negative trends were found. An increase of 15.8 events over the 99th percentile per decade was observed for Estonia. The indices selected for this study may be called ‘soft’ climate extremes, but the number of such events is large enough to allow for meaningful trend analysis in a roughly half-century long time series.

    Opis:
    Two-third of the area of the Netherlands is flood prone. Storm surges at the North Sea , floods in the rivers, failure of secondary dikes, as well as heavy rainfall may cause flooding. Most of the flood prone areas rely for their existence on drainage by pumping, because their surface level may be permanently or during floods up to several metres below the surrounding water levels. During the past decades climate change is generally felt as a reason for major concern. However, the impacts of climate change on increase in extreme conditions may be up to 45% per century. If we look at the man-induced changes in land use, due to increase in population and rapid increase in the value of public and private property, then one may observe an increase of 100-1,000% per century. One should therefore wonder what would have to be our major concern. In the paper the relevant processes are described, based on some characteristic data on water management and flood protection in the Netherlands . It is shown that impacts of climate change on water management and flood protection may be expected, but that such impacts can easily be accommodated during improvement works on water management systems and flood protection provisions that from time to time will be required. It will be much more important to take carefully into account the risk of flooding in the planning of land use development, especially for valuable types of land use like urban and industrial areas, green houses and recreation areas.
    Dwie trzecie powierzchni Holandii jest narażonych na powodzie. Sztormowe spiętrzenia wód na Morzu Północnym, wysokie stany wody w rzekach, awarie obwałowań rowów czy obfite opady mogą powodować powodzie. Użytkowanie obszarów narażonych na zalewanie zależy od stałego odwodnienia i od pompowania wód, ponieważ ich powierzchnia może (trwale lub tylko w czasie zalewu) znajdować się do kilku metrów poniżej poziomu otaczających wód. W ciągu ostatnich dziesięcioleci zmiany klimatu są postrzegane jako główny powód do niepokoju. Jednakże, wpływ zmiany klimatu może spowodować straty w wyniku wzrostu zjawisk ekstremalnych do 45% na stulecie. Jeśli spojrzymy na wywołane przez człowieka zmiany w użytkowaniu ziemi spowodowane przyrostem zaludnienia i gwałtownym wzrostem wartości infrastruktury to stwierdzimy, że przyrost strost może wynieść od 100 do 1000% na stulecie. W związku z tym należy zapytać, co powinno być przedmiotem naszej szczególnej troski? W oparciu o charakterystyczne dane dotyczące gospodarki wodnej i ochrony przeciwpowodziowej w Holandii opisano w pracy wyniki analiz prognostycznych. Wykazano, że można oczekiwać wpływów zmian klimatu na gospodarkę wodną i ochronę przeciwpowodziową, ale te wpływy dadzą się łatwo uwzględnić przy pracach związanych z usprawnianiem systemów gospodarki wodnej czy środków ochrony przeciwpowodziowej, które od czasu do czasu trzeba będzie podejmować. Daleko bardziej istotne będzie zwrócenie szczególnej uwagi na ryzyko powodziowe w planowaniu przestrzennym, zwłaszcza w odniesieniu do zagospodarowania cennych obszarów takich jak tereny miejskie czy przemysłowe, obiekty ekologiczne czy tereny rekreacyjne.

    Opis:
    It is widely known and accepted that the global climate is changing with unprecedented speed. Climate models project increasing temperatures and changes in precipitation regimes which will alter the frequency, magnitude, and geographic distribution of climate-related hazards including flood, drought and heat waves. In the mining industry, climate change impacts are an area of research around the world, mostly in relation to the mining industry in Australia and Canada, where mining policies and mitigation actions based on the results of this research were adopted and applied. In Poland, there is still a lack of research on how climate change, and especially extreme weather events, impacts mining activity. This impact may be of particular importance in Poland, where the mining industry is in the process of intensive transition. The paper presents an overview of hazardous events in mining in Poland that were related to extreme weather phenomena. The needs and recommended actions in the scope of mitigating the impact of future climate change on mining in all stages of its functioning were also indicated. The presented analyses and conclusions are the results of the first activities in the TEXMIN project: The impact of extreme weather events on mining activities, identifying the most important factors resulting from climate change impact on mining.
