Introduction. Reducing the negative impact of global warming and adapting to its devastating effects is an urgent global problem. Its decision is actively taken care of by politicians, leading world organizations and the expert community. Problems. Political, financial and economic, innovative, scientific and technical approaches and measures to reduce and / or neutralize climate change are widely discussed. World organizations - IPCC, IEA, WMO, IMF, etc. - are involved in solving the problems. Purpose. Assess the state of the problem, present the results of research and measures and tools for their implementation to reduce the greenhouse effect and / or adapt to its negative impact. Materials and methods. Authoritative literature sources with analysis of approaches, measures and tools to reduce greenhouse gas emissions, including the diversification of the fuel and energy balance of world energy resources, were used. Possibilities of adaptation to climate change are considered. Results. The main approaches and mechanisms of man-caused nature to actually reduce greenhouse gas emissions and global temperature in the 20th century are identified and their estimates for the period up to 2050 are given. The crucial role of RES and energy efficiency in the use of energy resources has been confirmed. Conclusions. It is likely that by the middle of the 20th century the world economy can be brought to a state of low-carbon development primarily through the use of renewable energy, energy efficiency, diversification of primary energy resources and their decarbonization, which will significantly reduce annual emissions of 10 carbon .

Is Implementation

This chapter outlines the challenge facing us. The Paris Agreement sets a target maximum of 2°C global warming and a preferred limit of 1.5°C. Yet, the subsequent combined national pledges for emission reduction suffice only for limiting warming to roughly 3°C. And because most nations are falling considerably short of meeting their pledges, even greater warming may become locked in. Something more drastic and wide-ranging is needed: a multi-pronged strategy. These different prongs to the climate-change solution are introduced in this chapter and explored one by one in the following chapters. First is rapid, massive reduction of greenhouse gas emissions. Second is implementation of ways to remove greenhouse gases from the atmosphere. Third may be increasing the reflectivity of Earth to incoming sunlight, to cool certain places down more rapidly. In addition, we need to protect ourselves from climate-change impacts that have already become inevitable.

Volatile halogenated gases and nitrous oxide used as part of a balanced general anesthetic may contribute to global warming. By avoiding volatile inhalational agent use, regional anesthesia may reduce greenhouse gas emissions and help prevent global warming. We present a theoretical calculation of the potential benefits and a real-life example of how much regional anesthesia may reduce greenhouse gas emissions.

SUMMARYSuitable fertilization is crucial for the sustainability of rice production and for the potential mitigation of global warming. The effects of fertilization on porewater nutrients and greenhouse-gas fluxes in cropland, however, remain poorly known. We studied the effects of no fertilization (control), standard fertilization and double fertilization on the concentrations of porewater nutrients, greenhouse-gas fluxes and emissions, and rice yield in a subtropical paddy in southeastern China. Double fertilization increased dissolved NH4+ in porewater. Mean CO2 and CH4 emissions were 13.5% and 7.4%, and 20.4% and 39.5% higher for the standard and double fertilizations, respectively, than the control. N2O depositions in soils were 61% and 101% higher for the standard and double fertilizations, respectively, than the control. The total global warming potentials (GWPs) for all emissions were 14.1% and 10.8% higher for the standard and double fertilizations, respectively than the control, with increasing contribution of CH4 with fertilization and a CO2 contribution > 85%. The total GWPs per unit yield were significantly higher for the standard and double fertilizations than the control by 7.3% and 10.9%, respectively. The two levels of fertilization did not significantly increase rice yield. Prior long-term fertilization in the paddy (about 20 years with annual doses of 95 kg N ha−1, 70 kg P2O5 ha−1 and 70 kg K2O ha−1) might have prevented these fertilizations from increasing the yield. However, fertilizations increased greenhouse-gas emissions. This situation is common in paddy fields in subtropical China, suggesting a saturation of soil nutrients and the necessity to review current fertilization management. These areas likely suffer from unnecessary nutrient leaching and excessive greenhouse-gas emissions. These results provide a scientific basis for continued research to identify an easy and optimal fertilization management solution.

Changes in seasonal weather cycles, a growing number of extreme phenomena, an upward trend in temperature and changes in the distribution of rainfall, significantly affect the functioning and effectiveness of agriculture. However, agriculture plays a major role in the emergence and intensification of these phenomena. The aim of the article is to present, analyse and evaluate the relations between agriculture and climate, with particular emphasis on greenhouse gas (GHG) emissions from agriculture in these relations. A cause-and-effect analysis was conducted based on literature studies, using the descriptive statistics method and analysis of the development trend. The basis for analysis were data on GHG emissions in the European Union (EU-28). The contribution of agriculture to the EU’s greenhouse gas emissions, albeit slightly but still increasing in recent years. The level of this emission is determined primarily by the type of agricultural activity conducted – animal production is definitely responsible for higher emissions than plant production. It is difficult to present a universal model of agricultural adaptation to climate change and a set of actions limiting the negative impact of agricultural production on climate. This is hindered by both the specificity of the agricultural sector and the large diversity of local conditions and applied farming practices. The opportunity to increase the effectiveness of actions taken may be a better connection between the implementation of objectives including the reduction of the causes and negative consequences of climate change and the objectives of sustainable agricultural development.

Introduction. Despite the global pandemic, reducing the negative effects of global warming and adapting to its devastating effects remains a pressing global problem. Its solution is actively taken care of by politicians, the world's leading scientific organizations and the expert community. Problems. Political, economic, innovative, scientific, technical and social approaches and measures to reduce and/or neutralize climate change and adapt to warming are widely discussed. World organizations - IPCC, IEA, WMO, etc. are involved in solving the problems. Goal. Assess the state of the problem, present the results of research and measures and tools for their implementation to reduce greenhouse gas emissions and/or adapt to their negative impact, in particular, in the energy sector - the largest producer of emissions. The main emphasis is on improving the energy efficiency of energy end-use, in particular, disseminating the experience of operational O&M (operation and maintenance) maintenance of passive buildings "zero-energy" in their energy supply from RES, as well as economic and financial leverage to reduce greenhouse gas emissions. Materials and methods. Authoritative recent literature sources with analysis of approaches, measures and tools to reduce greenhouse gas emissions are used. Weather-dependent (climatic) maintenance of the diagnostic-demonstration passive house of the "zero-energy" type with continuous system monitoring of parameters of engineering systems and building constructions and meteorological environment is organized. Results. Experience has been gained in the development and use of innovative energy-efficient technologies for energy supply of a demonstration passive house with O&M service by means of monitoring weather indicators and adaptation measures to climate change. Conclusions. The accumulated experience in the development of innovative energy efficient energy supply technologies and adaptation measures to climate change in O&M maintenance of zero-energy ITTF building of the NAS of Ukraine can be used in energy, in particular in municipal energy, and for the development of low-carbon energy. The use of approaches related to the taxation of excessive greenhouse gas emissions, or taking into account the decarbonization of the economy of production of goods and services in export-import operations, will also help reduce global warming.

On the one hand, this paper examines the costs directly caused by climate change, also com- paring the possible costs for preventing damage; on the other hand, it compares the effects of the radiation propulsion caused by anthropogenic greenhouse gas emissions on anthropogen- ic heat generation through the use of all types of fuels. In addition to the global warming ef- fect caused by anthropogenic heat radiation, there are also local heat islands that are affect- ed by a much greater rise in temperature. Purpose: A cost comparison of the damage caused by climate change and a quantitative com- parison of the direct heat development through the use of fuels with the radiative forcing through anthropogenic greenhouse gas emissions.Design / methodology / approach: In both cases, the research method is based on the analysis of public databases such as the International Energy Agency (IAE), as well as published lit- erature on global energy supply and the Federal Statistical Office. Results: The expected consequential damage caused by climate change will probably present most states with insoluble financial burdens. The radiation propulsion from anthropogenic greenhouse gas emissions makes an 80 times greater contribution to global warming than the anthropogenic heat generation from all types of fuels. Research / practical implications: Future research should show the consequences for the economy and the acquisition of money on the one hand and on the other hand include the ef- fects of global warming and the heat islands, both of which lead to a loss of habitat. Originality / Value: This paper has both the expected follow-up costs in view as well as the causes and effects of anthropogenic greenhouse gas emissions.

The 2007 Bali conference heard repeated calls for reductions in global greenhouse gas emissions of 50 per cent by 2050 to avoid exceeding the 2°C threshold. While such endpoint targets dominate the policy agenda, they do not, in isolation, have a scientific basis and are likely to lead to dangerously misguided policies. To be scientifically credible, policy must be informed by an understanding of cumulative emissions and associated emission pathways. This analysis considers the implications of the 2°C threshold and a range of post-peak emission reduction rates for global emission pathways and cumulative emission budgets. The paper examines whether empirical estimates of greenhouse gas emissions between 2000 and 2008, a period typically modelled within scenario studies, combined with short-term extrapolations of current emissions trends, significantly constrains the 2000–2100 emission pathways. The paper concludes that it is increasingly unlikely any global agreement will deliver the radical reversal in emission trends required for stabilization at 450 ppmv carbon dioxide equivalent (CO 2 e). Similarly, the current framing of climate change cannot be reconciled with the rates of mitigation necessary to stabilize at 550 ppmv CO 2 e and even an optimistic interpretation suggests stabilization much below 650 ppmv CO 2 e is improbable.

Abstract. Climate has changed over the past century due to anthropogenic greenhouse gas emissions. In parallel, societies and their environment have evolved rapidly. To identify the impacts of historical climate change on human or natural systems, it is therefore necessary to separate the effect of different drivers. By definition this is done by comparing the observed situation to a counterfactual one in which climate change is absent and other drivers change according to observations. As such a counterfactual baseline cannot be observed it has to be estimated by process-based or empirical models. We here present ATTRICI (ATTRIbuting Climate Impacts), an approach to remove the signal of global warming from observational climate data to generate forcing data for the simulation of a counterfactual baseline of impact indicators. Our method identifies the interannual and annual cycle shifts that are correlated to global mean temperature change. We use quantile mapping to a baseline distribution that removes the global mean temperature related shifts to find counterfactual values for the observed daily climate data. Applied to each variable of two climate datasets, we produce two counterfactual datasets that are made available through the Inter-Sectoral Impact Model Intercomparison Project (ISIMIP) along with the original datasets. Our method preserves the internal variability of the observed data in the sense that observed (factual) and counterfactual data for a given day remain in the same quantile in their respective statistical distribution. That makes it possible to compare observed impact events and counterfactual impact events. Our approach adjusts for the long-term trends associated with global warming but does not address the attribution of climate change to anthropogenic greenhouse gas emissions.
