Indices of the radiation-and-temperature regime in the Steppe zone of Ukraine in the period of 1986 through 2005, as compared to the expected changes in these indices, calculated in accordance with the two climate change scenarios, RCP4.5 and RCP8.5, for the period of up to 2050, are under consideration in the paper. RCP4.5 is a scenario of stabilization of greenhouse gas emissions into the atmosphere, while RCP8.5 is the one of very high greenhouse gas emissions. To characterize the radiation and thermal resources in the Steppe zone of Ukraine in the period of 1986 through 2005 (the basic period), and the change in the period of 2021 through 2050 calculations of average long-term values for the first group of environmental factors were performed: the duration of daytime, the total daily solar radiation, the intensity of photosynthetically active radiation (PAR), the accumulated PAR, the radiation balance of the vegetation cover, and the temperature regime. The following principal agro-climatic characteristics of the temperature regime were considered: dates of stable rise of the air temperature above 0, 5, 10, 15 °C in spring and autumn, duration of the period with air temperatures above 0, 5, 10, 15 °C, the accumulated positive air temperatures for the period with air temperatures above 0, 5, 10, 15 °C, the average air temperature in January and July, and the amplitude. It is pointed out that in the period of up to 2050, according to the calculations in both scenarios, increased indices of the radiation-and-temperature regime will be observed. The values of the radiation regime parameters will predominantly increase in late summer and early autumn. As a result of the inflow of increased accumulated solar radiation, the accumulated temperatures in the period with air temperatures above 5 °C will also rise. The expected increase in the accumulated temperatures will nevertheless not exceed 200 °C. A rise in the total temperature will contribute to better heat supply for the crops.

AbstractThe risk of kidney stone presentations increases after hot days, likely due to greater insensible water losses resulting in more concentrated urine and altered urinary flow. It is thus expected that higher temperatures from climate change will increase the global prevalence of kidney stones if no adaptation measures are put in place. This study aims to quantify the impact of heat on kidney stone presentations through 2089, using South Carolina as a model state. We used a time series analysis of historical kidney stone presentations (1997–2014) and distributed lag non-linear models to estimate the temperature dependence of kidney stone presentations, and then quantified the projected impact of climate change on future heat-related kidney stone presentations using daily projections of wet-bulb temperatures to 2089, assuming no adaptation or demographic changes. Two climate change models were considered—one assuming aggressive reduction in greenhouse gas emissions (RCP 4.5) and one representing uninibited greenhouse gas emissions (RCP 8.5). The estimated total statewide kidney stone presentations attributable to heat are projected to increase by 2.2% in RCP 4.5 and 3.9% in RCP 8.5 by 2085–89 (vs. 2010–2014), with an associated total excess cost of ~ $57 million and ~ $99 million, respectively.

Article in question investigates indicators of the moisture-temperature regime for the period of 1986 - 2005 (base period) and compares them to their expected changes calculated for different scenarios of climate change GFDL-30 %, A1B, A2, RCP4,5 and RCP8,5 for the period of 2021 - 2050 on the territory of Ukraine. Calculations reviled that most abrupt changes in moisture-temperature indicators in different soil-climatic zones of Ukraine can be expected in case of scenarios GFDL-30 %, А1В and А2. In case of scenarios of climate change RСР4,5, RСР8,5 thermal indicators are expected to be at the level of multilevel averages in all natural and climatic zones of Ukraine, except for Southern Steppe, where they are expected to grow. The greatest changes in all areas are expected under scenario GFDL-30 %, and they will increase from north to south. Under scenario А1В the greatest difference between calculated values and average multi-year values will be observed in the Forest-Steppe zone and in the Southern Steppe. Under scenarios RCP4,5 и RCP8,5 significant changes in the temperature regime are predicted only for the south and east of Ukraine. At the same time, according to the scenario of RCP4.5, a significant increase in seasonal winter air temperatures is forecasted. Analysis of the results of calculations for different climatic scenarios of water availability indicators for different natural and climatic zones of Ukraine for the period from 2021 to 2050 reviled that the most drastic changes in the climatic parameters of humidification are expected in the case of the scenarios GFDL-30 %, A1B and A2. In case of climate change scenarios RCP4.5, RCP8.5, no quick changes in the distribution of precipitation over the territory of Ukraine should be ex-pected. The greatest amount of precipitation for the year and in average for the seasons of the year is projected for the western regions of the country, the least one - for the southern regions. At the same time, for most regions the trend to increase the amount of precipitation is most likely in the case of the development of the GFDL-30 %, A1B and A2 scenarios. However, according to the scenarios RCP4.5 and RCP8.5, rainfall is expected to decline for the year as a whole and especially in the summer season in comparison with the actual for 1986 - 2005.

<p><b>Abstract </b></p> <p>While the pedagogical benefits of fieldtrips have long been recognised our ever increasing understanding of the impacts of flying on climate change is presenting educators with a poignant dilemma; the many benefits long associated with international fieldtrips are at odds with the world community’s needs in limiting/halting climatic change. In response, the paper presents the concept of a VR-based virtual fieldtrip as an innovative and carbon-sensitive type of (educational) travel. The paper not only makes the case for virtual fieldtrips as a meaningful learning tool but also explores both the virtual fieldtrip’s impact on Greenhouse Gas emissions and climate change-related learning. On both accounts the initial findings in this paper are very encouraging. More in-depth research is now required to not only develop a deeper understanding of the full breadth of benefits, but also of the diverse weaknesses presented by virtual fieldtrips and how to negotiate them.</p>

Waste management has an influence on the greenhouse gas (GHG) formation. The emissions of greenhouse gases vary between the EU countries depending on waste treatment practices and other regional factors such us composition of waste. The aim of this paper was to examine, from a life-cycle perspective, Municipal Solid Waste (MSW) management in the context of greenhouse gas formation and to evaluate the possible reduction of climate change potential of alternative waste management options in Estonia. The paper summarises the results of a case study in Estonia, assessing the climate change impact by 2020 in terms of net greenhouse gas emissions from two possible management scenarios. As a result it can be concluded that better management of municipal waste and diversion of municipal waste away from landfills could significantly reduce the emissions of GHG and, if high rates of recycling and incineration with energy recovery are attained, the net greenhouse gas emissions may even become negative. It means that these waste management options can partly offset the emissions that occurred when the products were manufactured from virgin materials and energy was produced from fossil fuels. This is especially important concerning the climate change impact.
