Climate change is an extreme natural change condition due to global warming that cannot be avoided, and will have a broad impact on various aspects of life, including the agricultural sector. The impact of climate change that occurs in the agricultural sector, namely flood and drought that cause plants to crop failure , is becoming greater, causing significant reduction in agricultural production, especially rice, requiring that farmers have the ability to adapt to climate change. The purposes of this study are to analyze the relationship between the performance level of agricultural extension workers and the capacity level of farmers in regard to climate change adaptation, and to analyze the relationship between the level of farmer capacity in climate change adaptation and rice productivity. The research was conducted in Central Lampung Regency in 2019 using a total of 100 rice farmers. The data analysis method used is Spearman rank correlation analysis. The results show that the performance level of agricultural instructors is significantly related to the level of knowledge capacity, attitude, and skills of farmers in climate change adaptation. Knowledge capacity, attitude, and skills of farmers in climate change adaptation are significantly related to rice productivity.

Russia is the world’s largest gas exporter and Germany is its most important market. Moreover, natural gas is a centerpiece of the Russian economy and the backbone of its energy supply to the Russian population. In terms of its external gas relations, Germany has always kept a special and strategic position, both in terms of volumes, but also in substance. This contribution explores the impact of the energy transition on the bilateral gas relationship. It argues that the bilateral gas relationship has been subjected to various paradigm shifts in the past, but, until recently, the relationship has been seen as in line with the strategic energy triangle of climate change/sustainability, supply security and economic competitiveness. This perception has come into question over two issues: climate change and supply security. Moreover, Germany’s authority over the conduct and the legal framework of bilateral gas relations has been increasingly contested, by Brussels, but also horizontally by other EU member states. At this stage, it is very uncertain whether both sides will manage to maintain and redefine their close energy partnership to address climate change. Decarbonizing the gas value chain would be a centerpiece. This would require a political shift away from securitization to decarbonization, not only in Germany, but even more so in the EU, and in particular, in Russia.

Abstract As climate change continues, anticipating species’ responses to rising temperatures, requires an understanding of the relationship between metabolic rate and thermal sensitivity, which itself may vary over space and time. We measured metabolic rates of three representative marine invertebrate species (hermit crabs Pagurus hirsutiusculus, periwinkle snails Littorina sitkana, and mussels Mytilus trossulus) and evaluated the relationship between thermal sensitivity (Q10) and thermal history. We tested the hypothesis that thermal history drives thermal sensitivity and quantified how this relationship differs over time (short-term to seasonal time scales) and between species. Organisms were collected from tide pools in Sitka, Alaska where we also recorded temperatures to characterize thermal history prior to metabolic rate assays. Using respirometry, we estimated mass-specific oxygen consumption (MO2) at ambient and increased temperatures for one individual per species per tide pool across three seasons. We evaluated relationships between thermal sensitivity and pool temperatures for time periods ranging from 1 day to 3 months prior to collection. For all species, thermal sensitivity was related to thermal history for the shorter time periods (1 day to 1 week). However, the direction of the relationships and most important thermal parameters (i.e., maximum, mean, or range) differed between species and seasons. We found that on average, P. hirsutiusculus and L. sitkana were more thermally sensitive than M. trossulus. These findings show that variability in thermal history over small spatial scales influences individuals’ metabolic response to warming and may be indicative of these species’ ability to acclimate to future climate change.

Climate change is one of the significant and threatening problems worldwide. It has attracted the attention of scientists and politicians as well as writers and critics especially in the western world. Writers have responded by writing climate change fiction despite the challenges of representation. James Bradley, an Australian novelist and critic, is one of those writers who are deeply occupied by the impacts of climate change. He has written Clade (2017) which traces the life of Adam Leith, a climatologist, and his family descendants amid the disastrous consequences of climate change. To analyze this novel, the researcher focuses on solastalgia, and applies the approach of everyday aesthetics. In a nutshell, the paper attempts to highlight the impact of climate change, examine the relationship between the characters and their environment, and explore the possibility of adaptation and detection of aesthetic values in an environment destroyed by climate change.

This paper presents the results of a classification of the Tatra lakes based on the duration of their ice cover, altitude, volume, and potential incoming solar radiation (PISR). It is embedded in the context of the impact of current climate change on the mountain environment. A digital elevation model, morphometric data, satellite imagery from the winter seasons of 2015-2017 and the Wrocław taxonomy method were used in the study. It was found that the order of freezing and thawing of the lakes investigated may change from year to year. The relationship between ice cover duration and altitude is clearly weakened by variations in lake volumes, with insolation having a noticeably lesser effect. Determining the duration of ice cover of the lakes over several seasons facilitates identifying the similarities and dissimilarities between them. Five groups of lakes displaying similar characteristics were identified as well as 2 groups of lakes with highly individual characteristics. Based on the data obtained, it can be concluded that the duration of ice cover on the Tatra lakes has been shortening noticeably over the last 100 years. Small high-altitude lakes seem to be most vulnerable to climate change.

This paper aims to analyze the relationship that may exist between climate change and cereal yield in Morocco. In order to study this correlation between variables, we used the most common form of regression model which is the multiple linear regression model. There are two main uses of multiple linear regression model. The first one is to quantify the weight of impact that the independent variables had on the dependent variable. The second use is to predict not only the relationship that may found between variables but also their impacts. In our case, we have chosen temperature and precipitation as an independent variables and cereal yield as dependent variable.

The negative effects of global climate change and the impact of rising surface air temperatures are already evident. Among the many echoes of these processes are the melting of glaciers, the reduction of the ice cover of the northern seas, the gradual disappearance of permafrost, sea level rise, soil erosion, and extreme weather events such as floods, hurricanes, droughts, and forest fires. As a result, the world's freshwater resources, public health and the well-being of the environment are under threat. Annually renewable fresh water resources, represented by the annual flow of rivers, are of undoubted value. Our goal was to identify the relationship of meteorological parameters, such as surface air temperature and precipitation in the high-altitude region of the Central Caucasus, with water consumption in the lowland territory of the Caucasus on the example of the river.Terek (art. Kotlyarevskaya). These studies are particularly valuable from the point of view of the relationship between climate change and its further impact on the hydrological cycle of the lowland regions of the Caucasus. In the course of the research, the relationship was revealed, indicating that the distribution of river flow over the territory of the Caucasus corresponds to the distribution of the annual amounts of surface air temperature and the annual amounts of atmospheric precipitation.

Climate change is an emerging issue particularly in agricultural research as it is observed that the climate change has unfavorably distressed the agricultural production in different regions in India. Therefore, the present study has empirically examined the relationship between climate change and agricultural production in the selected districts of Odisha, India using a Panel Autoregressive Distributed Lag (PARDL) model over the period 1993 to 2019. The study found that the climate variables have adversely affected the crops production in the districts of Odisha. In order to minimize the impact of climate change on crops production in the state, there must have implementation of various policies and adaptive strategies by the government and farmers.

The knowledge of climate change effects on variations of winter wheat yields are crucial for productions. Our objectives were to investigate the relationship between yield-related indices of winter wheat and the related climatic variables (selected using variance inflation factors) at the 20 sites of Xinjiang, China over 1981–2017. The background of climate and yield changes was analyzed from temporal and spatial respects. The number of independent climatic variables was selected with the variance inflation factor method to remove the multicollinear feature. The Pearson correlation was conducted between the first difference values of climatic variables and yield-related indices of winter wheat (namely plant height, growth period duration, 1000-kernel weight, kernel number per ear, biomass and yield) to find the key climatic variables that impacted winter wheat growth and yields. The multi-variate linear and nonlinear functions were established step by step using the selected key climatic variables. The best function was determined for each site (significant for p < 0.05). From the results, there were general wetter and warmer trends of the climatic variables. Correspondingly, shortened winter wheat phenology and increased growth and yields were observed for most sites. Still, the climatic trends had mixed effects on winter wheat yields. The effects of precipitation, mean air temperature and relative humidity on plant height and growth period duration agreed well. Different sites had different major climatic drivers for winter wheat growth or yields, and the best functions of growth and yields could be linearly or nonlinearly, mostly described by multi-variate functions. The winter wheat growth or yield indices were also found to be closely connected with the soil water content status at the eight sites. The relationship between winter wheat growth or yield and climate provided useful references for forecasting crop production and for projecting the impact of future climate changes.
