Global Warming Cause and Mitigation

GlobalWarming: Cause and Mitigation

GlobalWarming

Theoccurrence of climate change can be attributed to natural factors aswell as human activities. Examples of the natural causes includevolcanic activities and an increase in solar output (Khan, 2012).Some of the key examples of human causes include industrial emissionsand deforestation. Most of the natural causes occur in the form ofspecific events that take a given period of time. The human causes,on the other hand, are continuous. However, the fact that somenatural (including volcanic activities) and human factors (such asindustrial operations) result in emission of greenhouse gases is oneof the key similarities between the two kinds of the causes of changein climate.

Evidenceof the Global Warming

Thetruth about the occurrence of global warming has been questionedseverally, but there is sufficient evidence to show that it is a realglobal phenomenon. Scientists have established a correlation betweencarbon dioxide concentration in the atmosphere and a change in thelevel of temperature (Collider, 2011). In addition, the melting ofpolar ice is a clear proof of the fact that temperatures have beenincreasing with time. Skeptical scholars should understand that arise in the temperature takes many years, which makes it difficult tonotice the change.

MitigationStrategies

Thereare two major strategies that are being used to contain the rate atwhich global warming is taking place. Carbon sequestration isconsidered as an effective measure that can be used to reduce thequantities of greenhouse gases that are released each year into theatmosphere. It is estimated that the sequestration of one ton ofcarbon dioxide costs $ 50 (Collider, 2011). However, sequestrationcan only be effective if the stakeholders will establish long-termpolicies. Long-term policies are required in order to ensure that thequantity of greenhouse gas that leaks every year is less than onepercent. Therefore, policies will focus on the provision ofguidelines and resources to finance sequestration as a long-termproject.

Carbontaxing is currently considered as the most cost-effective approachthat can be applied in minimizing emissions that result from thehuman activities. This strategy is implemented by levying some taxeson each type of fuel depending on its carbon content. The strategyfinances its enforcement and implementation processes since itinvolves the collection of funds. Its effectiveness is associatedwith the fact that it discourages people from using fuels that havehigh carbon content (Congress of the U.S., 2013). This strategy iscost-effective because expenses are mainly incurred during theformulation of laws. It affects the government policies by forcingthe stakeholders to establish guidelines that will encourage peopleto consume fuels with less carbon content.

PolicyChanges

Policychanges should focus on the establishment of the limits on carbonfootprint for each country and develop alternative energy sources.These policy changes should mainly target the transport and themanufacturing sectors, since they are the largest contributors ofcarbon emissions in the modern world (European Commission, 2015). Theproposed limits on carbon footprint should target China, the U.S.,the EU, and India since they emit 30 %, 15 %, 9.6 %, and 6.6 % of thetotal greenhouse gases released each year into the atmosphere(European Commission, 2015). The aforementioned economic sectors andcountries should be targeted because they are the global leaders interms of emission, which implies that limiting them through policieswill result in a significant reduction in the rate at which climatehas been changing.

Inconclusion, global warming is currently among the most debated issuesin the world. Although its occurrence can be attributed to human andnatural factors, there are measures that can be taken to contain it.However, policy measures should weight between the economic benefitsof different human activities and the impact of limiting the carbonthat they emit. Carbon taxing and sequestration are some of the mostcost-effective approaches that the stakeholders in the environmentalprotection sector should consider.
