Naturaland Anthropogenic Climate Change
Climatechange involves the alteration in the distribution of the normalweather patterns especially when such events occur for an extendedperiod. In most instances, the weather conditions or time variationof the meteorological situations become different. Climate change iscaused by several factors which can either be natural or humanactivities. Biotic processes, disparities in solar radiation, platetectonics and volcanoes are also causes of climate change.Apparently, human activities are recognized as the most significantcauses of the recent global warming effects. Anthropogenic climatechange mainly refers to the emission of greenhouse gasses. Theseemissions include carbon dioxide, methane, and nitrous oxide. Aconsiderable amount of anthropogenic climate change is due to theburning of fossil fuels namely coal and petroleum. Likewise, land usechange such as deforestation and agricultural activities alsoincrease the emission of components that are associated with globalwarming. Examples of naturally occurring effects include changeswithin the sun itself, such as its intensity and variations in thetrajectory and angle of the earth’s axis that causes fluctuationsof sunlight in various regions. Other natural causes includeemissions from volcanic eruptions, movement of crustal plates, andthe El-Niño Southern Oscillation[ CITATION Cae12 l 1033 ].
Is Taking Place?
Thequestion as to whether global warming is real or not has raised hugeunending debates in various countries and communities. However,despite the state of denial in some individuals, it is now clear thatthis happening is existent. Apparently, the extent of shiftingweather and climate is dependent on the amount of greenhouse gassesthat are emitted by human activities and to a lesser extent bynatural occurrences. Substantial evidence points that indeed globalwarming is taking place. First of all, both lab and atmosphericassessments have shown the greenhouse gasses have the capability ofabsorbing heat. There is also a significant increase in globaltemperatures of about 0.850Cand a rise in sea level by almost 20cm over time. Additionally,assessment of events including sunspots and volcanoes do notsufficiently explain the warming trend. There have been changes suchas reduced snowfall in the Northern Hemisphere, glacier retreats andshrinking of permafrost covered areas. Other events includealterations in the weather patterns, major flooding, and heat waves.Continuous tracking shows that every year, overall temperaturesincrease and the year 2015 is approximated to be the warmest everrecorded period [ CITATION Mar15 l 1033 ].
Thisapproach is based on the application of alternative energy sourcesthat are cleaner compared to the existing ones. Such strategiesinclude the use of gas instead of coal, implementation of nuclearpower, use of renewable sources of energy for instance hydropower,solar, wind geothermal and bioenergy. Combined heat and electricityis also another technique that can be effective. Furthermore, carbondioxide can be tapped for use early and stored. Mostly, the totalamount of greenhouse gasses and other pollutants that increase theprogression of global warming are significantly reduced. Newtechnology offers a more workable approach to producing the requiredenergy without necessarily causing harm to the environment. Thisstrategy is likely to be efficient since the contemporary technologyhas shown the promise of delivering high outputs of energy withminimal pollution. However, the cost of running such projects isrelatively costly. Nuclear power, for example, is a very expensiveventure [ CITATION Wor16 l 1033 ].
HigherFuel Efficiency Standards
Fuelproficiency means minimal emissions of the gasses responsible forglobal warming. This mitigation method can be achieved by enhancingand encouraging the production of more fuel-efficient vehicles, theuse of hybrid cars, biofuels, shifting to alternative modes oftransport such as rail or public transport. Non-motorized movementsuch as walking and cycling can be emphasized. Transportationplanning, high-efficiency airplanes, electric vehicles andutilization of powerful and reliable batteries help in reducingemissions in the long-term. Competence regarding fuel consumption isan important aspect in the battle against global warming. By ensuringthat fuel utilization is as adept as possible, then the rate ofprogress of global warming and climate change can be considerablyreduced. This strategy can be a bit costly regarding infrastructure,but it is much easier to implement. For example, encouraging publictransport, use of trains and minimizing personal vehicle use areactivities that can be achieved without too much hassle [ CITATION Wor16 l 1033 ].
Thismethod is one of the best ways of reducing emissions. The systemsneed to be developed in a way that the manufacturers, industries, andvehicles with higher emissions are taxed heavily. This move is likelyto compel vehicle production companies to improve their products toconform to the stipulated conditions (Bosetti et al., 2012).
MoreInclination to Clean Energy
Thereare other alternative sources of energy. As such, relevantregulations need to be put in place that prescribes the maximumallowable use of these resources. For instance, petroleum imports canbe reduced to minimal levels or completely abolished. This change islikely to take effect in the countries that produce oil as well asthose companies which refine it [ CITATION Wor16 l 1033 ].
