Greenhouse gases have an important role in understanding earth climate history. Based on these studies greenhouse effect which produces heat due to trapping of heat by greenhouse gases in adjusting earth temperature, Climate change refers to the oscillations in earth global or regional climate in time interval and defines those changes that fluctua...

Coal is the major fossil fuel used for power generation in India. From the combustion of coal, the CO 2 emitted in the atmosphere is responsible for the enhanced greenhouse effect. The present communication is an attempt to provide a brief investigation of the schemes introduced by the Government of India to curb the CO 2 emissions. Several other s...
There is fully understood nowadays the fact that the present-day climate changes are a direct consequence of “greenhouse effect” inducing gases quickly accumulating in the atmosphere. Among those gases, carbon dioxide is by far the most important, its main source being the burning of fossil fuels. A central place within the strategies aimed at stab...

... The authors also showed that the high concentration of CO 2 can badly damage the density of marine plankton making seawater acidic. Samimi et al. (2013) also realized that climate change is the effect of rapid GHGs concentration. The authors suggested some techniques such as greenbelt and afforestation to reduce GHGs concentration. ...
Global warming is rapidly warming seawater and introducing acidification that adversely affects marine ecosystems. Consequently, temperature-sensitive fishery resources are under great threat, and if the current situation continues, global marine ecosystems could turn into an ecological desert by the end of the century. In this paper, we first formulate a nonlinear dynamic mathematical model to illustrate the adverse effects of global warming and rapid concentrations of greenhouse gas (GHG) on marine ecosystems. We then develop a control system adopting coastal forestation and plankton nutrients as two control techniques. Here, coastal forestation is adopted to lessen the concentration GHGs by absorbing carbon dioxide through photosynthesis, whereas plankton nutrients are applied to improve planktonic diversity that can provide more food to marine fishes. The purpose of the control system is to increase fish population in marine ecosystems by providing a suitable environment, i.e., proper temperature, low acidity, and sufficient food. The control system and how it can balance the situation are verified by analysis. We confirm the results by examining different cases compared with other articles. Results disclose that the control system can improve marine ecosystems increasing plankton’s density and fishery resources and reduce global warming and GHGs concentration. The results further show that the system is more effective if both control strategies are applied together instead of just one. Overall, this study suggests that fish population in marine ecosystems can be increased and the adverse effects of global warming can be reduced by implementing adequate coastal forestation and plankton nutrients.
... The world climate has been warming significantly due to the emissions of anthropogenic non-CO 2 greenhouse gases; whereas GHGs, especially CO 2 emitted from different combustion of fossil foul, have comparatively fewer impacts on global warming (Montzka et al. 2011). Samimi et al. (2013) discussed that GHGs are responsible for climate change and also added some major effects to the important environmental factors and some controlling techniques were briefly described, and Ledley et al. (1999) briefly discussed the factors of GHGs for which the environment is becoming warmer, and also the interrelation between GHGs and climate change. In particular, a set of alternative projections for future carbon dioxide in Bangladesh was statistically described depending on different growth rates of human population and gross domestic product (Gunter 2010). ...
At present, climate change is a burning issue which is being changed with the rising of atmospheric temperature due to the emissions of greenhouse gases (GHGs) in the environment. Climate change and the increasing amount of GHGs jointly impact the living beings near coastal areas introducing different and destructive natural disasters that confine their consecutive life-style. On the other hand, the forest area on the earth’s surface is decreasing gradually due to different purposes of human population. As a result, the environment and living beings near coastal areas will have to face a comprehensive natural threat at the end of the century. In this study, a non-linear mathematical model has been proposed to briefly describe the potential impact of GHGs on climate change rising atmospheric temperature and their combined harmful effect on living beings near coastal areas. After investigating the proposed model analytically and numerically, the numerical simulations have been performed to illustrate the effect of rapid emissions of GHGs on the other dynamics in support of analytical findings briefly. The article discloses the potential threat of increasing GHGs emissions on the environmental system.

... In this case, we first studied in-depth the relationships between rapid global warming, concentrations of GHGs, and types of coastal ecosystems. Following this, we gathered relevant data and/or environmental factors from research papers, articles, monographs, annual reports, etc., of governmental and non-government organizations [1,2,4,5,6,9,10,13,15,20,21,22,24,27,28]. Then, we did a detailed statistical analysis of the collected data after observing carefully the system, processes, and corresponding data, etc., to obtain the parametric values. ...
Global warming is adversely affecting the earth's climate system due to rapid emissions of greenhouse gases (GHGs). Consequently, the world's coastal ecosystems are rapidly approaching a dangerous situation. In this study, we formulate a mathematical model to assess the impact of rapid emissions of GHGs on climate change and coastal ecosystems. Furthermore, we develop a mitigation method involving two control strategies: coastal greenbelt and desulfurization. Here, greenbelt is considered in coastal areas to reduce the concentrations of GHGs by absorbing the environmental carbon dioxide (CO2), whereas desulfurization is considered in factories and industries to reduce GHG emissions by controlling the release of harmful sulfur compounds. The model and how it can control the situation are analytically verified. Numerical results of this study are confirmed by comparison with other studies that examine different scenarios. Results show that both control strategies can mitigate GHG concentrations, curtail global warming and to some extent manage climate change. The results further reveal that both control strategies are more effective than one control method. Overall, the results suggest that the concentrations of GHGs and the effects of climate change can be controlled by adopting sufficient coastal greenbelt and desulfurization techniques in various industries.

Today distribution method and atmospheric contamination emission muddling is vulnerable in city region because industrial units grow in underdeveloped countries and contaminated produced by this units. Atmospheric contaminated distribution muddling is method for estimate concentration level and contaminated concentration in different interval relative to emission source. This practice is restricted to step after events occurring without proper administering these programs and we have more timely and monetary cost. In this paper investigate concentration distribution study from 2 dimensional and non-permanent states in land surface. If there is barrier in front of chimney ,there is more contaminated gas distribution after chimney and maximum contaminated density is less in earth. When there are 3 chimney, There is no effect on contaminated density maximum distance. But in situation there is barrier in front of chimney, this distance is 1000 meter next to chimney. Earth atmosphere attack all kinds of contaminated due to industrial grow development and citizen grow. Modeling and investigating this contaminated distribution in environment surface uneven and kind of cover has basic role in contaminating distribution method because inhalator this contaminated in soil and ware have non-compensate damage to environment. One of the major concerns of industries is their effects on environment and sustainable development trend.
