Abstract:
This paper discusses the greenhouse gas emissions which cause the global warming in the atmosphere. In the 20th century global climate change becomes more sever which is due to greenhouse gas emissions. According to International Energy Agency data, the USA and China are approximately tied and leading global emitters of greenhouse gas emissions. Together they emit approximately 40% of global CO2 emissions, and about 35% of total greenhouse gases. The developed and developing industrialized countries together emit 90% of the global CO2 equivalent gases. Due to global warming the ocean levels are increasing, as a result most of the coastal areas will submerge by 2050, and some insects and animals will extinct. Hence immediate steps to be taken to reduce greenhouse gas emissions to safe the future generations. The paper emphasizes on the affects of global warming and different ways to reduce greenhouse gas emissions.Keywords:

A transition from the global system of coal-based electricity generation to low-greenhouse-gas-emission energy technologies is required to mitigate climate change in the long term. The use of current infrastructure to build this new low-emission system necessitates additional emissions of greenhouse gases, and the coal-based infrastructure will continue to emit substantial amounts of greenhouse gases as it is phased out. Furthermore, ocean thermal inertia delays the climate benefits of emissions reductions. By constructing a quantitative model of energy system transitions that includes life-cycle emissions and the central physics of greenhouse warming, we estimate the global warming expected to occur as a result of build-outs of new energy technologies ranging from 100 GWe to 10 TWe in size and 1‐100 yr in duration. We show that rapid deployment of low-emission energy systems can do little to diminish the climate impacts in the first half of this century. Conservation, wind, solar, nuclear power, and possibly carbon capture and storage appear to be able to achieve substantial climate benefits in the second half of this century; however, natural gas cannot.

AbstractAbstractThe origins and operation of the Intergovernmental Panel on Climate Change (IPCC) and some aspects of the greenhouse gas theory of global warming are examined. It is concluded that while it is extremely unlikely that any accurate prediction can be made now of the climate a century hence, and there is doubt that emissions of CO2 from man's activities are a major causative factor in global warming, government initiatives based on acceptance of the theory provide the spur for the steel industry to seek process routes with CO2 emissions much lower than they are today.Keywords: GLOBAL WARMINGCARBON DIOXIDEIRON AND STEEL INDUSTRYEMISSIONS

Agriculture directly contributes about 10%-12% of current global anthropogenic greenhouse gas emissions, mostly from livestock. However, such percentage estimates are based on global warming potentials (GWPs), which do not measure the actual warming caused by emissions and ignore the fact that methane does not accumulate in the atmosphere in the same way as CO2 . Here, we employ a simple carbon cycle-climate model, historical estimates and future projections of livestock emissions to infer the fraction of actual warming that is attributable to direct livestock non-CO2 emissions now and in future, and to CO2 from pasture conversions, without relying on GWPs. We find that direct livestock non-CO2 emissions caused about 19% of the total modelled warming of 0.81°C from all anthropogenic sources in 2010. CO2 from pasture conversions contributed at least another 0.03°C, bringing the warming directly attributable to livestock to 23% of the total warming in 2010. The significance of direct livestock emissions to future warming depends strongly on global actions to reduce emissions from other sectors. Direct non-CO2 livestock emissions would contribute only about 5% of the warming in 2100 if emissions from other sectors increase unabated, but could constitute as much as 18% (0.27°C) of the warming in 2100 if global CO2 emissions from other sectors are reduced to near or below zero by 2100, consistent with the goal of limiting warming to well below 2°C. These estimates constitute a lower bound since indirect emissions linked to livestock feed production and supply chains were not included. Our estimates demonstrate that expanding the mitigation potential and realizing substantial reductions of direct livestock non-CO2 emissions through demand and supply side measures can make an important contribution to achieve the stringent mitigation goals set out in the Paris Agreement, including by increasing the carbon budget consistent with the 1.5°C goal.

This study addresses climate changes issue related to greenhouse gases emissions. Earth suffered in time a series of major changes in climate and we are now in a process of gradual warming, which can have devastating consequences. It is now accepted that greenhouse gases produced by human activities, but not only, are the main cause of this issue because of their high global warming potential. Scientific studies have shown that the substances that act as greenhouse gases adsorbing and emitting infrared radiation are: water vapors (H2O), carbon dioxide (CO2), methane (CH4), nitrous oxides (N2O), ozone (O3) and Chlorofluorocarbons (CFC). The study took into account the climate changes that occurred for processing sets of relevant statistical indicators, in order to analyze and identify appropriate solutions to decrease the impact of greenhouse gas emissions. Have been analyzed the main aspects of the quantity of greenhouse emissions, during 2003-2010, released into the atmosphere both at the global level: in the Romanian Center Region and at local level: in counties of the region. Through processing data obtained from environmental reports, studies and specific documents were formulated conclusions that can be useful in proposing measures and action plans for reducing emissions of greenhouse gases.

A common view is that the current global warming rate will continue or accelerate. But we argue that rapid warming in recent decades has been driven by non-CO2 greenhouse gases (GHGs), such as CFCs, CH4 and N2O, not by the products of fossil fuel burning, CO2 and aerosols, whose positive and negative climate forcings are partially offsetting. The growth rate of non-CO2 GHGs has declined in the past decade. If sources of CH4 and O3 precursors were reduced in the future, the change of climate forcing by non-CO2 GHGs In the next 50 years could be near zero. Combined with a reduction of black carbon emissions and plausible success in slowing CO2 emissions, this could lead to a decline in the rate of global warming, reducing the danger of dramatic climate change. Such a focus on air pollution has practical benefits that unite the interests of developed and developing countries. However, assessment of ongoing and future climate change requires composition-specific longterm global monitoring of aerosol properties.

At least one recent report and numerous news articles suggest that carbon dioxide (CO2) emissions are rising more rapidly than expected. While CO2 emissions associated with human activities continue to rise -- and may be worthy of alarm because of their influence on climate change -- any short-term comparisons between actual emissions and the Intergovernmental Panel on Climate Change (IPCC) scenarios miss the mark. This report analyzes this issue and the issues associated with IPCC scenarios and trajectories. It also describes the importance of monitoring CO2 emissions and analyzing the factors and forces behind increasing CO2 emissions.

It has been recognized worldwide that the utilization of an enormous amount of fossil fuel has created various adverse effects on the environment, including acid rain and global warming. An increase in average global temperatures of approximately 0.56 K has been measured over the past century. This increase is called global climate change or global warming. The gases with three or more atoms that have higher heat capacities than those of O 2 and N 2 cause the greenhouse effect. Carbon dioxide (CO 2 ) is a main greenhouse gas associated with global climate change. Nitrous oxide (N 2 O), chlorofluorocarbons (CFCs), methane (CH 4 ) are other important greenhouse gases. Collectively, they are projected to contribute, directly, about as much potential global warming over the next 60 years as CO 2 . Three trace gases, HFCs, PFCs, and SF6, would be regulated under the 1997 Kyoto Protocol because of their global warming potential and for their potential growth of concentrations in the atmosphere. HFCs have been widely approved as substitutes for CFCs.
