Climate changes have been observed in Poland the recent decades and more pronounced climate changes are projected for the future. They impact on the natural and built environment of Poland, which has been shaped by both circulation of energy and matter, typical for moderate latitudes, and the properties of the landscape, inherited from the geological past. In the present paper, consequences of climate change (corresponding to model-based projections) for spatial organization of Poland have been reviewed.

The warming of the climate of the Earth has been unequivocal, most notably due to the mancaused increase of atmospheric concentration of greenhouse gases, leading to intensification of the greenhouse effect. Projections for the future explain that we are commited to further, possibly even more intense, warming, whose rate depends on the scenario of socio-economic development and effective climate change mitigation policy. If the global emissions grow in uncontrolled way and carbon sequestration potential decreases, the warming can attain a dangerous dimension. Global warming induces change in all variables of hydroclimatic systems. As demonstrated in the present contribution, the impacts of global climat change – both advantageous and (more often) adverse can be noted in all regions of the globe and in all systems and sectors, some of which are particularly vulnerable. Yet, many of these impacts can be avoided, reduced, or delayed, by effective climate change mitigation.

Recent investigations have demonstrated global sea level rise as being due to climate change impact. Probable changes in sea level rise need to be evaluated so that appropriate adaptive strategies can be implemented. This study evaluates the impact of climate change on sea level rise along the Iranian south coast. Climatic data simulated by a GCM (General Circulation Model) named CGCM3 under two-climate change scenarios A1b and A2 are used to investigate the impact of climate change. Among the different variables simulated by this model, those of maximum correlation with sea level changes in the study region and least redundancy among themselves are selected for predicting sea level rise by using stepwise regression. Two Discrete Wavelet artificial Neural Network (DWNN) models and a Discrete Wavelet Adaptive Neuro-Fuzzy Inference system (DWANFIS) are developed to explore the relationship between selected climatic variables and sea level changes. In these models, wavelets are used to disaggregate the time series of input and output data into different components. ANFIS/ANN are then used to relate the disaggregated components of predictors and predictand (sea level) to each other. The results show a significant rise in sea level in the study region under climate change impact, which should be incorporated into coastal area management.

We are currently in the period of an intensive climate change, resulting from changes in the heat balance of the earth’s surface and causing an increase in the temperature of the lower troposphere levels. According to the latest IPCC report of 2021, it is human activity that has indisputably caused the increase in atmospheric concentrations of greenhouse gases, responsible for this process. The consequences of climate change under Polish conditions, apart from a rise in temperature especially in the spring and winter months, are also changes in the amount and distribution of precipitation totals. A slight increase in precipitation totals is observed, however heavy rainfall is significantly more frequent, interspersed with periods of droughts and heatwaves. Ground frost-free periods are prolonged, and a negative trend in the duration and thickness of snow cover is recorded in most parts of the country. Although extreme phenomena occurring in Poland are permanently inscribed in its climatic conditions, the threat of strong winds has been increasing in recent years, and the intense precipitation that often accompanies them is the cause of peak discharges and flooding. Forecasts for progressive climate change are not optimistic, either on a global scale or for the country in question. The article examines the impact of climate change on the design, construction and maintenance of engineering structures globally and for Poland. Changes in design standards, selected examples of disasters and solutions to adapt and build resilience to climate change have been analysed. For most building disasters, climatic factors were the direct cause of the disaster, although in the course of the analysis it has usually turned out that the disasters exposed human errors in the design, construction and, to a lesser extent, the improper maintenance of engineering structures. However, there is an increasing number of new approaches to creating a climate change resilient built environment, including the latest one, which proposes to use the grey infrastructure of cities to build resilience to climate change.

W latach 2010 i 2011 wystąpiło w Polsce kilka miesięcy o temperaturze poniżej średniej z wielolecia. Jednak, w skali globalnej, cały rok 2010 był rekordowo ciepły i zakończył najcieplejsze dziesięciolecie w historii bezpośrednich obserwacji temperatury. Był to 34. kolejny rok o temperaturze globalnej wyższej niż średnia z XX w. Temperatura globalna rośnie od 40 lat, a począwszy od lat 1960. każda dekada była cieplejsza od poprzedniej. Zmiany nie są jednak regularne w czasie i przestrzeni - na zaobserwowany trend wzrostowy nakłada się silna zmienność naturalna. Zmiany klimatu nie są niczym nowym, bowiem w historii Ziemi okresy chłodniejsze wielokrotnie przeplatały się z cieplejszymi. Mechanizmy historycznych zmian klimatu były całkowicie naturalne. Obecnie ziemski klimat ociepla się najprawdopodobniej przede wszystkim z powodu wywołanego przez ludzi wzrostu stężenia atmosferycznego gazów cieplarnianych. Projekcje na przyszłość przewidują dalsze, jeszcze bardziej intensywne, globalne ocieplenie i ta tendencja wydaje się przesądzona co najmniej na kilkadziesiąt lat. W istocie z temperaturą zmieniają się wszystkie elementy sprzężonych systemów klimatu i zasobów wodnych, a w konsekwencji - także wielu systemów fizycznych, biologicznych i ludzkich (społeczno-ekonomicznych). Konsekwencje - zarówno korzystne, jak i negatywne - można dostrzec, i spodziewać się ich w przyszłości, we wszystkich regionach świata oraz we wszystkich sektorach i systemach. Zaistnienie i wielkość konsekwencji zależą od scenariusza rozwoju społeczno-ekonomicznego, który ma wpływ na emisję gazów cieplarnianych, oraz od realizowanej polityki przeciwdziałania zmianom klimatu. Prawdopodobieństwo dotkliwych konsekwencji zmian klimatu rośnie wraz ze wzrostem szybkości i amplitudy zmian. Ocenia się, że przy znaczniejszym ociepleniu straty przeważałyby globalnie nad korzyściami. Skoro działalność człowieka jest odpowiedzialna za większą część obecnego ocieplenia, to poprzez właściwe kształtowanie ludzkiej działalności można próbować ograniczać ocieplenie w dalszej perspektywie. Ponieważ jednak globalny system klimatyczny cechuje się znaczną bezwładnością, więc nie jesteśmy w stanie skutecznie wpływać na klimat najbliższych dziesięcioleci. W efekcie można oczekiwać globalnego ocieplenia rzędu 0,2 stopni Celsjusza na dekadę. Natomiast wielkość ocieplenia w następnych dziesięcioleciach będzie można ograniczyć poprzez skuteczną politykę ochrony klimatu, tzn. redukcję emisji gazów cieplarnianych i zwiększenie ich wiązania, podjęte odpowiednio wcześnie. Bez efektywnej polityki klimatycznej poziom ocieplenia w horyzoncie roku 2100 będzie zapewne znacznie wyższy niż względnie bezpieczny wzrost o 2 stopnie Celsjusza ponad temperaturę z okresu przedprzemysłowego. Człowiek zaadaptował się do już istniejącego klimatu, więc każda zmiana wymaga dostosowania się do nowych warunków i generuje koszty. W Polsce zmiany klimatu niosą szanse - bardziej przyjazną, wyższą temperaturę wody w Bałtyku, a zimą - mniejszą zachorowalność i śmiertelność oraz oszczędność na opale. Są jednak i zagrożenia: wzrost częstości fal upałów, opadów intensywnych, powodzi i osuwisk, ale też suszy w sezonie wegetacyjnym, silnych wiatrów i wzrost poziomu morza. Per saldo, Polska na pewno nie będzie wielkim przegranym w zmieniającym się klimacie, jednak np. problemy z okresowymi deficytami lub niszczącymi nadmiarami wody mogą się nasilić. Trzeba będzie optymalnie "zagospodarować" zmiany korzystne, a skutecznie zaadaptować się do zmian niekorzystnych. Konieczna jest wielka rozwaga i dyplomatyczna zręczność, by wynegocjować w Unii Europejskiej takie warunki zobowiązań dotyczących polskiego wkładu w przeciwdziałanie zmianom klimatu, które nie przyhamują społeczno-gospodarczego rozwoju Polski. Nasz kraj "węglem stoi", więc perspektywa wysokiego opodatkowania emisji dwutlenku węgla i zagrożenie tzw. "wyciekaniem węgla", a w konsekwencji utrata miejsc pracy w Polsce na rzecz krajów, które nie uczestniczą w światowym przeciwdziałaniu zmianom klimatu, mogą być powodem do obaw. Nie może być tak, że dla Polski kuracja jest gorsza od choroby. Nasza wiedza na temat przyszłych warunków jest jednak bardzo ograniczona i obarczona znacznym elementem niepewności.

In the years 2010 i 2011, there have been several months in Poland with temperature below the long-term monthly mean. However, in the global scale, the year 2010 was record-warm and terminated the globally-warmest decade in the history of direct temperature observations. It was the 34-th consecutive year with global temperature exceeding the 20th century average. Global temperature has been growing for 40 years and since 1960s, each decade is warmer than the former one. However, changes are not regular in time and space - there is a strong natural variability superimposed on the growing trend. Climatic changes have occurred many times in the history of the Earth - there were many cooler periods interspersed with warmer periods. However, mechanisms of earlier climatic changes have been totally natural. Presently, it is very likely that the Earth climate warms up primarily due to anthropogenic increase of atmospheric concentration of greenhouse gases. Projections for the future foresee further, and more intense, global warming and this tendency is projected to last for at least several decades. In fact, temperature changes are accompanied with changes of all elements of the coupled systems of climate and water resources, and in consequnce - many physical, biological, and human (socio-economic) systems. Climate change impacts, both advantageous and disadvantageous, can be observed already, and are expected in the future, in all regions, sectors, and systems. They depend on the scenario of socio-economic development that drives the emissions of greenhouse gases, and on the climate change mitigation policy. Probability of severely adverse impacts grows with the level and rate of warming. It is estimated that for a larger warming, negative effects would dominate over positive effects. If human activity is responsible for the most part of the recent warming, we can try to restrict the warming in a longer perspective by changing the human behaviour. However, due to the inertia of the climate system, we cannot influence the climate of the nearest decade or two, so that the warming of 0.2 centigrade per decade is expected. The amplitude of warming in 2050-2100 can be restricted by an effective climate mitigation policy, i.e. reduction of emission of greenhouse gases and increase of carbon sequestration, undertaken sufficiently early. Without effctive climate policy, the global warming in the time horizon of the year 2100 will be much higher than the relatively safe increase by 2 centigrade above the pre-industrial temperature. People have already adapted to the existing climate, hence every change of climate requires adaptation to new conditions and generates costs. In Poland, climate change bring opportunities, such as higher, hence more enjoyable water temperature in the Baltic Sea, and in winter - lower morbidity and mortality, and savings on heating. However, there are also threats: increase of frequency of heat waves, intense precipitation, floods and landslides, but also droughts in vegetation seasons, strong winds, and sea level rise. All in all, Poland will not be a big looser in the changing climate, even if problems with temporary deficits or destructive abundance of water can become more severe. It is necessary to benefit of positive changes and to adapt to negative changes. Prudence and diplomatic skills are needed in negotiations with the European Union. The obligations on the Polish contribution to climate mitigation cannot inacceptable delay the socio-economic development. Our country "sits on coal", hence the perspective of high tax on emission of carbon dioxide and the threat of carbon leakage, and in consequence loss of jobs in Poland to countries that do not partake in the global climate policy can be reasons for concern. It would be inacceptable that in Poland the cure is worse than the disease. However, our knowledge about future conditions is very limited and loaded with a considerable uncertainty.

A crucial part of every adaptation planning and disaster risk reduction is estimation of vulnerable areas and risk in the future. Only a well-developed monitoring system could bring valuable information to create possible scenarios to set up adaptation plans. Monitoring systems of meteorological conditions, surface water, groundwater, landslides, seacoast, agricultural drought as well as their standards and methodologies, are crucial for establishing an effective warning system of every country, and thus are the subject of research conducted by national institutes. Therefore, the conditions of this national research (getting trained staff, equipment etc.) is essential to provide reliable information for a national adaptation plan and for economic assessment of climate change impacts. Poland has significant experiences in monitoring systems, data collecting and visualizing, as well as in the development of scenarios and risk maps. Methodologies and capacity building, necessary for their use, along with experiences and lessons, learned to get valuable information for disaster risk reduction, were presented by the authors from the research during the 24th session of the Conference of the Parties to the United Nations Framework Convention on Climate Change (COP 24) in Katowice (December 2018). The presentation contributed to the global adaptation process through experience sharing that is important for the relevant research conducted in the least developed countries.
