Usuallypeople pay attention on daily weather changes and how the weather will bethrough the week or the month, but do we pay attention on climate change how itaffects our lives. Did we ask ourselves what are the causesof climate change? How climate change impacts our activities? Can we dosomething to solve this big issue before to turn to a big disaster? These questions make me think deeply how wework to solve this problem because the earth is the only place so far we can liveon it. Climate change has become aworldwide problem and this issue affects human lives, environment, social andeconomic. The change in climate has serious impacts on our natural ecosystemand as human we should face it before causing great catastrophe such as wateravailability, agriculture, rising sea levels and health.
Manystudies recognize that sign of change is increasing in average temperatures,snow and rainfall, patterns are shifting, and extreme climate events arebecoming more common in our days. These changes are expectedto grow if we don’t solve the issues or the causes of climate change. Firstwhat is climate change? Climate change is an imbalance in typical climaticconditions such as heat, wind patterns and precipitation that characterizeevery region on earth. Whenwe talk about climate change at the global level, we mean changes in theEarth’s climate in general. Thepace and magnitude of long-term global climate changes have enormous impacts onnatural ecosystems.Second,what are the causes of climate change? Natural phenomena suchas volcanic eruptions or variations in the intensity of solar radiation areprobable causes. However; The presenceof natural cover of greenhouse gases in the atmosphere keeps the planet warmenough for life, as we know it, but the emission of greenhouse gases caused byhuman made the cover thicker, so stores heat and leads to global warming.Fossil fuels are the single largest source of man-made greenhouse gases.
Theburning of coal, oil and natural gas releases billions of tons of carbon eachyear, which would otherwise have been hidden in the ground, as well as largeamounts of methane and nitrous oxide. More carbon dioxide is released whentrees are cut down and no trees are planted. At the same time, large chunks oflivestock are emitted from methane, methane is also emitted from rice farms andlandfills, and nitrous oxide is produced from the use of fertilizers.Long-lived gases such as CFCs, HFCs and PFCs used for air conditioning andrefrigeration are produced by industry and ultimately enter the atmosphere.
(The Intergovernmental Panel on ClimateChange).Certain human activities are today the first cause of this increase ofthe phenomenon. The buildings and the exaggerated consumption of energyare the main ones. In areas such as the Polar Regions, energy is usedextensively for home heating. Human Influences on Global WarmingHuman influence has been a very serious issue now because human do not takecare the earth.
Older engines, especially those used in developing countries inparticular, emit a lot of gases that contribute to the destruction of the ozonelayer. These are all parts of society whose operations need to berethought. Thirdly, what are the consequences of climate change?Climate change is not a small difference in climate patterns.
Temperatureswill lead to changes in weather patterns such as wind patterns, the amount ofprecipitation and species,as well as the types and frequency of several possible climatic events. Climatechange in this way can have profound environmental, social and economicconsequences and is unpredictable. Somepossible consequences are:1. Lossof drinking water stock Within 50 years, the number of people suffering fromdrinking water shortages will increase from 5 billion to 8 billion people. 2. The declineof the agricultural crop It is obvious that any change in the overall climateto be affected by local agriculture and thus reducing the stock of food. 3. Decreasingsoil fertility and worsening erosion: Changingplant habitats, increasing drought and changing precipitation patterns willexacerbate desertification.
Theuse of chemical fertilizers will be automatically increased indirectly andtoxic contamination will be exacerbated. 4. Pestsand diseases: Hightemperatures are favorable conditions for the spread of pests and insectscarrying diseases such as mosquitoes carrying malaria.
5. Highsea level: Thewarming of the world will extend the mass of ocean waters, in addition to themelting of large glaciers such as Greenland, which is expected to raise the sealevel from 0.1 to 0.
5 meters by the middle of the century. This potential risewill pose a threat to coastal communities and their cultivation, as well asfreshwater resources on the coast and the presence of some islands that will beflooded. 6. Frequentclimatic disaster: Thehigh frequency of droughts, floods, storms and others harms communities andtheir economies. Humanityhas never faced such a huge environmental crisis.
Ironically, developingcountries with less responsibility for climate change will suffer the worstconsequences. Weare all responsible for seeking to stop this problem immediately. Ifwe fail to take action now to stop global warming, we may suffer irreversibleconsequences.Finally the solution to stop climate change, sincethe burning of fossil fuels is the main source of greenhouse gases; we shouldreduce our dependence on oil as a primary source of energy.
Alternative solutionsexist: “peaceful” renewable energy and rational use of energy. Natureoffers a range of alternative options for energy production. Asenergy conservation is rationalized, renewable energy resources such as sun,air, waves and biomass provide efficient, reliable and environmentally friendlysources to generate the energy we need and the quantities we want. Theimplementation of these solutions will not require any concession by citizensto their lifestyles, but will enable them to enter a new era of energy thatwill bring them economic prosperity, employment opportunities, technologicaldevelopment and environmental protection.Wewill focus on alternative solutions available to suppliers with the mostadvanced technologies in this fieldTheEarth receives enough solar radiation to meet the growing demand for solarsystems. Theproportion of sunlight that reaches the Earth’s surface is enough to providethe world’s energy needs 3000 times.
Eachsquare meter of land is exposed to the sun, on average, enough to generate 1700kWh of energy each year. Thesun is converted to electricity and the direct current that is generated is stored inbatteries or converted to a current on the grid through an electricaltransformer.Magnificentmirrors focus the sunlight in a single line or point. The heat produced isused to generate steam. Hotsteam is used to run turbines that generate electricity.
In sun-flooded areas,solar thermal power plants provide large amounts of electricity. Astudy conducted by Greenpeace under the title “Solar thermal power plants2020” in cooperation with the European solar thermal industry concludedthat the amount of solar energy produced around the world could reach 54billion kWh by 2020. In 2040, it is possible to generate more than 20% of totalelectricity demand.
Theuse of wind power has reached advanced stages. Air power is acomprehensive phenomenon and the most renewable sources of renewable energybased on modern technology clean, effective, sustainable, and no pollution. Thecurrent wind turbines are very sophisticated technology – they are adjustable,easy to install and operate, and are able to generate more than 200 times thepower of the world today.Inconclusion, we need to take part and try to stop global warming and othereffects on climate change. If the earth’s temperatures continue to rise in thefuture, living things on earth would become extinct due to the hightemperatures. If humans contribute to control global warming, this world wouldbe cooler and the high temperatures we currently have would decrease.
Ifeverybody as one take stand and try to end most of the climate changes that areoccurring, this world would be a safer place to live on.
