Global climate change is defined as a process that affects all living things and ecosystems globally and is claimed as the most critical problem of the current century. Turkey, which is shown as one of the most affected countries by this process, is among the “countries at risk.” It is stated that the temperature will increase throughout the country until 2100, and this increase may reach 6 ºC. In order to determine the possible effects of global climate change, it is necessary to predict how the climate structure and basic parameters may change. From this point of view, this study is aimed to determine the change of temperature and precipitation, climate types (according to De Martonne, Lang, and Emberger climate classification) which are the most critical climate parameters until 2050 and 2070 in Düzce, one of the important cities of our country. The current situation and possible changes in 2050 and 2070 have been compared using RCP 4.5 and RCP 8.5 scenarios. As a result of the study, the temperature, precipitation, and related climate types would change significantly throughout the province of Düzce, and this change will show itself as a significant temperature increase and change in precipitation regime. In addition, a shift in climate types towards continental climate types is predicted until 2070. In order to avoid the destructive effects of global climate change, it is recommended to take measures on a sectoral basis.

Global climate change is seen as a process that will directly or indirectly affect living things and ecosystems all over the world. In this process, determining the changes in climate parameters and climate types in advance is of great importance in terms of the measures that can be taken and the preparation for the process. In this study, it is aimed to determine the changes that may be caused by global climate change in some climate parameters and climate types in Mersin, which is one of the important cities of our country. Within the scope of the study, the current status of temperature, precipitation and climate types (according to De Martone and Emberger climate classification) and RCP 4.5 and RCP 8.5. It is aimed to compare the possible situations in 2050 and 2070 in the light of scenarios. The results of the study show that temperature, precipitation and climate types will change significantly throughout Mersin province. Today, the temperature varying between -0.4°C and 19°C will change between 4.9°C and 24°C throughout the province in 2070 according to the RCP 8.5 scenario, that is, there will be an increase of around 5°C in the temperature change interval, the precipitation regime will change, Climate types are predicted to shift towards arid climates. This situation shows that climate factors, one of the most important planning criteria, will change significantly in landscape planning studies. Since landscape planning studies continue their effects for many years, it is recommended to take this into consideration in order to make a healthy planning. The results of this study should be used in the planning studies for Mersin province.

AbstractWithin the mountain altitudinal vegetation belts, the shift of forest tree lines and subalpine steppe belts to high altitudes constitutes an obvious response to global climate change. However, whether or not similar changes occur in steppe belts (low altitude) and nival belts in different areas within mountain systems remain undetermined. It is also unknown if these, responses to climate change are consistent. Here, using Landsat remote sensing images from 1989 to 2015, we obtained the spatial distribution of altitudinal vegetation belts in different periods of the Tianshan Mountains in Northwestern China. We suggest that the responses from different altitudinal vegetation belts to global climate change are different. The changes in the vegetation belts at low altitudes are spatially different. In high-altitude regions (higher than the forest belts), however, the trend of different altitudinal belts is consistent. Specifically, we focused on analyses of the impact of changes in temperature and precipitation on the nival belts, desert steppe belts, and montane steppe belts. The results demonstrated that the temperature in the study area exhibited an increasing trend, and is the main factor of altitudinal vegetation belts change in the Tianshan Mountains. In the context of a significant increase in temperature, the upper limit of the montane steppe in the eastern and central parts will shift to lower altitudes, which may limit the development of local animal husbandry. The montane steppe in the west, however, exhibits the opposite trend, which may augment the carrying capacity of pastures and promote the development of local animal husbandry. The lower limit of the nival belt will further increase in all studied areas, which may lead to an increase in surface runoff in the central and western regions.

Abstract. In this study, the impact of global climate change on the temperature and precipitation regime over the island of Cyprus has been investigated. The analysis is based on daily output from a regional climate model (RCM) at a high horizontal resolution (25 km) produced within the framework of the EU-funded ENSEMBLES project. The control run represents the base period 1961–1990 and is used here as reference for comparison with future predictions. Two future periods are studied, 2021–2050 and 2071–2100. For the study area and over the study period, an analysis of the changes associated with the temperature regime and the hydrological cycle, such as mean precipitation and drought duration, is presented. Variations in the mean annual and seasonal rainfall are presented. Changes in the number of hot days/warm nights as well as drought duration are also discussed. These changes should be very important to assess future possible water shortages over the island and to provide a basis for associated impacts on the agricultural sector.

Global climate change will affect all living things on this planet. For many species, the change in their environment may mean extinction. However, there is one organism, the mosquito, that may benefit from changes in the climate. This paper addresses the possible effects of climate change on mosquitoes, including longer breeding seasons and increased hatch rates of populations. The enlarged population will cause mosquitoes to seek more territory, and the warmer climate will in turn make more territory available. If mosquitoes increase in population, there may be an amplification of mosquito-borne diseases such as malaria, yellow fever, Chikungunya virus, St. Louis encephalitis, West Nile virus, and the Zika virus. This trend of increased range because of climate change has already been observed in dengue fever. This information can be used as an engaging segue into teaching students about climate change and vector-borne disease.

The concern about the climate issue has been increasing since climate change influence the water resources system. For this reason, this study sought to identify the presence of trends in the historic series of two meteorological variables: total annual precipitation and number of rain days, in the state of Bahia, Brazil, in order to verify if the precipitation regime is being affected by the global climate change. Two trend tests were applied: Mann-Kendall and Linear Regression, with significance levels of 5% and 10%, in the historical series of 32pluviometric stations distributed throughout the state. The results of the two testes were similar, which guarantees that both can be used for detection of changes in rain pattern. The study confirms that in a specific region of Bahia, more specifically in the central and eastern areas, there is a reduction trend in the historical series of annual precipitation. Regarding the number of rain days, no trend conclusions were observed.

AbstractUrban trees provide vital ecosystem services such as mitigating heat island, improving air quality by removing various air pollutants, capturing rainwater, and acting as topsoil carbon storage. The aesthetic value of urban trees is also another feature that has to be considered in the context of urban greening. Classical criteria for the selection of urban trees have to respond to new challenges imposed to the cities in a near future. Global climate change factors increase the harshness of our cities, and thereby the plant resilience to abiotic stresses has also to be seriously considered for planning the urban greening. Red-leafed species, characterized by the permanent presence of foliar anthocyanins, show a greater tolerance to different environmental cues than green-leafed species commonly used in our cities. In addition, red tree species own a great aesthetic value which has been underestimated in the context of urban areas, especially in the harsh Mediterranean cities. In this study, we emphasize the “privilege of being red” from different point of view, in order to drive the attention to the possibility to increase the use of red-leafed species for urban “greening”. Some possible negative aspects related to their use are rebutted and the direction of future researches are proposed.

A investigação das tendências climáticas e das possíveis mudanças do comportamento climático associado aos registros de alterações climáticas globais auxilia na redução da vulnerabilidade às oscilações do regime de precipitação. Este trabalho teve como objetivo avaliar as tendências climáticas da precipitação pluviométrica e dos índices de extremos climáticos no município de Garanhuns, Pernambuco - Brasil. Foram utilizados dados diários de precipitação no período de 1961 a 2014, fornecidos pelo Instituto Nacional de Meteorologia-INMET. Para atingir o objetivo proposto foi utilizado o software Climap para analisar a tendência da precipitação e dos índices de extremos climáticos, assim como o teste sequencial de Mann-Kendall para verificar o ano aproximado em que as tendências tiveram início. Os resultados indicaram que não houve tendências nas séries dos totais anuais e nos índices de extremos de precipitação. Porém, constatou-se uma possível alteração na série de precipitação total anual a partir de 2003, e a predominância da alta variabilidade anual da precipitação pluviométrica na região.  ABSTRACT   The investigation of climate trends and possible changes in climate behavior associated with records of global climate change helps in reducing vulnerability to fluctuations in precipitation regime .

Abstract. After focusing on the changes in Hungarian temperature and preeipitation during this Century, possible hydrological, agricultural and ecological consequences of a future climate change are described. These results have been obtained using a modified version of empirical downscaling techniques, developed to analyse the local effects of global climate change in a twofold concentration of atmospheric greenhouse gases scenario. In addition, regional changes in temperature and precipitation were examined with the help of the more specific stochastic downscaling method. The climate of Hungary has become warmer and drier over the last Century. It is to be expected that an increasing concentration of atmospheric greenhouse gases will enhance the tendency towards aridification.
