<p>The occurrence of severe haze events remains a serious problem in Beijing. Previous studies suggested that the frequency of weather patterns conducive to haze may increase with global warming. The new Shared Socioeconomic Pathways (SSPs) cover a wide range of uncertainties in aerosol and greenhouse gases emissions. Global and Chinese aerosol emissions are projected to decrease in most SSPs, while increases in greenhouse gases and global warming will continue for the rest of the century. The future, therefore, remains unclear.</p><p>We quantified the air pollution over Beijing and associated weather patterns using multiple indices calculated from the SSPs</p><p>We show that the occurrence of weather patterns conducive to the formation of haze significantly increases by the end of the century due to increases in greenhouse gases. Aerosol reductions also cause an increase in their occurrence, but reduce the severity of haze, and overall reducing aerosol emissions will be beneficial.</p>

<p>Historical changes, spanning 1971–2016, in the Athens Urban Heat Island (UHI) over summer were assessed by contrasting two air temperature records from established meteorological stations in urban and rural settings. When contrasting two 20-year historical periods (1976–1995 and 1996–2015), there is a significant difference in summer UHI regimes. The stronger UHI-intensity of the second period (1996–2015) is likely linked to increased pollution and heat input. Observations suggest that the Athens summer UHI characteristics even fluctuate on multi-annual basis. Specifically, the reduction in air pollution during the Greek Economic Recession (2008-2016) probable subtly changed the UHI regime, through lowering the frequencies of extremely hot days (T<sub>max</sub> > 37 °C) and nights (T<sub>min</sub> > 26 °C).</p><p>Subsequently, we examined the future temporal trends of two different UHIs in Athens (Greece) under three climate change scenarios. A five-member regional climate model (RCM) sub-ensemble from EURO-CORDEX with a horizontal resolution of 0.11° (~12 × 12 km) simulated air temperature data, spanning the period 1976–2100, for the two station sites. Three future emissions scenarios (RCP2.6, RCP4.5 and RCP8.5) were implanted in the simulations after 2005. The observed daily maximum and minimum air temperature data (T<sub>max</sub> and T<sub>min</sub>) from two historical UHI regimes (1976–1995 and 1996–2015, respectively) were used, separately, to bias-adjust the model simulations thus creating two sets of results.</p><p>This novel approach allowed us to assess future temperature developments in Athens under two different UHI intensity regimes. We found that the future frequency of days with T<sub>max</sub> > 37 °C in Athens was only different from rural background values under the intense UHI regime. There is a large increase in the future frequency of nights with T<sub>min</sub> > 26 °C in Athens under all UHI regimes and climate scenarios; these events remain comparatively rare at the rural site.</p><p>This study shows a large urban amplification of the frequency of extremely hot days and nights which is likely forced by increasing air pollution and heat input. Consequently, local mitigation policies aimed at decreasing urban atmospheric pollution are expected to be also effective in reducing urban temperatures during extreme heat events in Athens under all future climate change scenarios. Such policies therefore have multiple benefits, including: reducing electricity (energy) needs, improving living quality and decreasing heat- and pollution related illnesses/deaths.</p><p> </p>

The nitrogen balance made on a national, regional and/or farm basis provides valuable information about the surplus of nitrogen in agricultural production. This surplus of nitrogen is dispersed into the environment, causing water pollution with nitrate and other compounds of nitrogen, air pollution with ammonia and nitrous oxide. The nitrogen balance in Polish agriculture has undergone vast changes during the last few years, according to economic and social transformations after the collapse of the communist system. The surplus of nitrogen decreased from about 90 kg N/ha in 1989 to about 60 kg N/ha in 1991. More than 30% of nitrogen surplus is volatilized into the atmosphere in the form of ammonia, while similar amounts find their way into the water, particularly groundwater. The amounts of nitrogen losses due to denitrification are difficult to estimate.

The article refers to the issues of various instruments of agricultural income support. They apply in the situation of risk occurrence in agricultural production and are regulated by both EU and Polish legislation. The article particularly concerns the proposal made by domestic legislator which aims to establish several income support funds. They would be a source of farmers’ remedies and support when the crises’ situation appears. The author states that the formulated income stabilization tool is the complementary one to the proposed EUs’ solutions and may contribute to the economic situation of some farmers in the future.

Problems associated with the growing shortage of natural resources and the relevance of the development of organic agriculture are revealed, as well as put forward proposals for solving these problems. Data on statistical and analytical sources are given. The information on biological and chemical methods of agricultural land cultivation in Uzbekistan was used. The information of authors from different countries on the greening of agricultural production is used. In conclusion, it is concluded that in the future, the development of organic agriculture should become one of the most important areas of agricultural policy.
