However, it may not occur in all regions of the world. Natural climate change is a result of normal atmospheric changes. It may be caused by several factors such as ocean variations, plate tectonics, orbital fluctuations, changes in solar output and tilt of the planet. On the other hand, anthropogenic climate change refers to the production of greenhouse gasses emitted by human activity. Human activities have increased the proportion of greenhouse gasses in the atmosphere over years. Both natural and anthropogenic climatic variations result in Earth’s energy balance. This energy balance describes how the incoming energy from the sun is used and returned to space. All the energy that fuels the earth comes from the sun. To ensure a constant global average temperature is maintained, all of the sun’s radiation that enters Earth’s atmosphere must be sent back to space. Both natural and anthropogenic climate changes lead to global warming. Natural climatic changes cause global warming through variations of carbon dioxide content in the atmosphere. Anthropogenic environmental change causes a dangerous atmospheric deviation through people discharging carbon dioxide transmitted by processing plants to the environment. Natural climatic changes are caused by normal atmospheric changes such as ocean variations, plate tectonic while anthropogenic climatic changes are caused by human activities such as carbon emissions and land use. (Ollhoff, 2010) Anthropogenic Climatic changes can be controlled by human beings since their activities cause them. This is achieved through implementation of strict standards. On the other hand, natural climatic changes cannot be controlled by human beings. Nature regulates them. Global warming and climate changes. 3 Global Warming Global warming is a gradual increase in the average temperature of the global atmosphere and the oceans. It already has a harmful effect on our health. Changes in temperature and precipitation under global warming are likely to lead to other consequences that threaten human health. Dangerous heat waves are becoming very common. These heat waves may cause skins injuries, illness or even death. An example is a vector-borne disease. Warm air, sunlight and pollution from power plants and cars burning coal and gasoline combine to produce smog, which humans experience as poor air quality. Global warming also has an adverse impact on the climate. Scientists in the past had predicted that these effects would result from global climate changes are now occurring. They include accelerated sea level rise, loss of sea ice, and longer, more intense heat waves. For instance, the 2001-2010 decade is the warmest since 1880. (Black & Weisel, 2010) Mitigation strategies for global warming Carbon sequestration Mitigating the damage caused by global warming is a responsibility that requires cooperation globally. Our future carbon dioxide emissions, as well as our future mitigating actions, will determine the degree to which human beings will suffer the consequences of our current behavior. Let us look at mitigation strategies put in place to curb global warming. One of these strategies is the carbon sequestration. It is the capturing of carbon dioxide from the atmosphere or human carbon dioxide from large-scale sources before it is released to the atmosphere. Once it is captured, it is stored in long-term storage. Carbon sequestration has significantly reduced the level of carbon in the atmosphere and also Global warming and climate changes. 4 carbon dioxide released to the atmosphere from human sources. There are two types of carbon sequestration. One is terrestrial sequestration that uses plants to capture carbon dioxide from the atmosphere and then store it as carbon in the stems and roots of the plants and the soil. It is a set of land management practices that maximizes the amount of carbon that remains stored in the ground and plant material for the long term. The other one is geologic sequestration. It is putting carbon dioxide into long-term storage in geologic zones deep underground. Geologic sequestration is the method of storage that is considered for carbon capture and storage projects. (Black & Weisel, 2010) The cost of carbon sequestration ranges between $30 and $90 per ton of carbon dioxide. There is a need to develop methodologies to estimate, monitor and report physical leakage from storage facilities. Measured responsibilities, discharge is exchanging, or other comparative systems need clear principles and strategies for representing outflows and evacuations. Clean coal technology Coal is the dirtiest of every single fossil fuel. At the point when blazed, it creates emanations that contribute to a great extent to a worldwide temperature alteration, water contamination and make corrosive downpour. To keep these impacts, clean coal innovation is put into utilization. It tries to diminish unforgiving ecological impacts by utilizing various changes to clean coal and contain its emanations. Some clean coal innovations cleanse the coal before it blazes. One kind of fuel planning is coal washing. It evacuates undesirable minerals by blending pulverized coal with a fluid. It then permits the pollutions to particular and settle. The other one is wet scrubbers. It is additionally called vent gas desulfurization frameworks. It uproots sulfur dioxide that is a noteworthy reason for a corrosive downpour. This is finished by Global warming and climate changes. 5 showering pipe gas with limestone and water. The blend responds with the sulfur dioxide to shape manufactured gypsum. The cost of implementing clean coal technologies ranges between $2 billion and $4 billion. . The objectives are to encourage and promote research and development that will lead to improved understanding of conventional combustion processes. It also aims at developing techniques that control and reduce solid, liquid and gaseous emissions associated with combustion processes. This is achieved by improving operating efficiency and identifying methods for the efficient utilization of combustion by-products. (Ollhoff, 2010) Proposed policy measures Climate policies need to be taken into account for both short term and long term goals. This will help stabilize the adverse climatic changes. I would propose a near-zero emissions campaign. If each and factories avoid emitting gasses to the atmosphere, it would be easy to deal with natural gasses in the atmosphere. Individuals should note that each increment of emission leads to another increment of warming. If we want to avoid additional warming, we need to prevent other emissions. If we reduce emissions to zero in the simulations, the level of carbon dioxide in the atmosphere slowly go down as carbon sinks such as the oceans and forests absorbed the gas. Based on this policy, the business sectors that should be given strict standards are refineries companies, petroleum firms, and horticulture industries. Global warming and climate changes.
