The periods of warming and cooling of the weather on Earth followed one another with great irregularity and caused significant variations in air temperature but allowed the existence of life and especially of the human species. In this paper we have analysed the variation of air temperature in Oltenia in the period 1961-2021. A number of our other works have analysed the variability of the climate in this part of Romania. After the warm period of 1945-1955, a gradual cooling of the weather followed in summers and during the period 1966-1984 (for 20 years). In summers, no thermal maximum of ≥40°C was registered. The period 2000-2021 (22 years) was the warmest of all the meteorological observations in Oltenia and many annual, monthly and daily climate records were surpassed. At the same time, during the analysed interval, the melting rate of the ice in the polar areas intensified a lot and exceptional thermal maxima were registered. The heat waves during the summers were more and more intense, more frequent and longer in duration. The paper is useful to all those interested in climate variability in Oltenia.

The preliminary determination of the article is to investigate the effects of pollution and climate change. In this regard, the authors want to highlight that this real and critical issue must take seriously because each of us contributes to pollution and climate change, which is very real, and which will be aggravated by not taking action. Global warming currently involves two major problems for humanity: on the one hand, the need to dramatically diminish greenhouse gas emissions to stabilize the concentration of these gases in the atmosphere to prevent anthropogenic influence on the climate system and enable ecosystems, contrastingly the need to accommodate to the consequence of climate change, given that these effects are already visible and inevitable due to the activity of the climate system, regardless of the outcome of emission reduction actions. The main problem with pollution is air quality, which has fallen considerably, especially in urban areas. The" World Health Organization" approximates, more than seven million people die each year from air pollution. The authors also conducted a case study on the local effects of climate change - Timișoara and its peri-urban area. Therefore, we concluded that if Timișoara is successful in reducing greenhouse gas emissions, this will create a test market for Romania's ecological technologies and help the environmental industries to locate in Timișoara.

Weather changes significantly affect people's lives. Climatic data recorded so far indicates a progressive warming of the weather. Agriculture is one of the most affected branches due to its dependence on the evolution of the weather throughout the entire plants growing season. Agroecology can be one of the correct and concrete answers to the challenge of climate change, as this type of agriculture respects the natural balance of Earth, reducing human impact as much as possible. The current research presents the situation of agroecology in our country, as well as the evolution of organically grown crops areas. Although over the last 10 years, in Romania, the trend has fluctuated slightly with both decreases and increases, starting with 2017 the evolution of organic cultivated areas follow a positive trend. Organic farming follows the same positive trend in European Union and also worldwide. As concerns the types of organic crops grown in Romania in 2019 the largest area is occupied by cereals (32.09%), followed by permanent crops of meadows and hayfields (29.2%), then by industrial crops (19.82%). The smallest ratios of organically cultivated areas are represented by tuberous and root plants, as well as vegetables. Wheat is the most widespread crop, followed by maize, sunflower and barley. Other organic crops in our country, but cultivated on smaller areas, are rye, triticale, oats, rice, soybeans, potatoes and sugar beets. The increase of the surfaces on which the agroecology extends corresponds to the necessity of the humanity to return to the natural state, just how agriculture was from its beginnings, in order to slow down the climatic changes.

This paper presents 22 indicators used to highlight the actual global warming trends. The indicators are the outputs of a detailed research activities performed by scientists from all over the world. These 22 indicators were divided into eight separate categories: atmosphere and climate; glaciers, snow and ice; marine systems; terrestrial ecosystems and biodiversity; water; agriculture; economy; human health. Some specific mountain area aspects are relieved with Mountain Low in Romania. [ABSTRACT FROM AUTHOR]

Global warming is an unanimously accepted phenomenon by the international scientific community, being already highlighted by the analysis of observational data over long periods of time, with an increase in temperature of over 1 °C. Climate change in Romania is part of the global context, taking into account the regional conditions, with an increasing trend of arid summer. While the link between high temperatures, climate change and rainfall has been modeled in detail, the situation is not the same for plant water accessibility. The period of time between 1898 and the present, corresponding to the annual records of precipitation and evapotranspiration, overlapped with important political and administrative changes in the studied area, and with extensive hydro-amelioration works. The aim of the paper is to statistically follow the evolution over time of precipitation, namely of evapotranspiration measured in Western Romania, which would allow the expression of conclusions regarding the improvement directions of the water regime. In order to follow the evolution in time of these data, the interval of 1898–2019 was divided into three periods: 1898–1950, 1951–1989 and 1990–2019, respectively. The increase in temperature, especially during the vegetation period and the large number of years in which evapotranspiration quantitatively exceeds the precipitation, indicating the need for effective measures to regulate the water balance.

The present paper examines the evolution of Romanian seaside tourism between 2008–2018 to find the connection between climate change and the number of total tourist arrivals. The vicious cycle of greenhouse gas emissions and climate change has become one of the most critical topics discussed due to its negative effect on the wellbeing of the planet and its impact on sustainable economic development in the long run. Various economic activities, including tourism, could be subject to dramatic changes due to global warming. Depending on the geographical location of tourist destinations, and the degree of fluctuation in climate indicators, there have been dramatic shifts in visitor flow. This situation has been aggravated as countries that were once famous for their summer season and seaside holidays are now affected by high temperatures. Such temperatures can hardly be tolerated by tourists, particularly those from the Nordic countries. By comparison, there are countries that have been known to have only two or three full summer months suitable for tourism at the seaside and which in the last years have had a more extended summer season. This situation could turn into a significant competitive regional economic advantage for countries such as Romania, at least in the short- and medium-term. In this context, we aim to investigate whether there are climatic conditions, such as the extension of the tourist season on the coast (in the case of destinations that have four seasons and are known for having a shorter number of summer days), that can be turned into advantages. In this regard, we have conducted exploratory research to analyse if there is a statistically significant correlation between the indicators regarding climate change and tourism arrivals on the Romanian seaside, namely Constanta county. For our study, we used secondary data, provided by the Romanian National Meteorological Administration and the National Institute of Statistics, and accumulated a detailed profile of Romanian seaside summer tourism in the context of actual climate changes and challenges. Climate change may have significant consequences on the tourism industry and economic growth as well. Information on the direct effects higher temperatures could have on tourism is lacking. Improving policy analysis is necessary to reduce uncertainties, further understanding, assess implications and enable the tourism industry to adapt to changing circumstances. [ABSTRACT FROM AUTHOR]
