Global warming Speech
Accordingto the scientific community, if the emissions of greenhouse continueincreasing, the planet earth will reach a point of no return. Globalwarming will turn to be catastrophic as well as irreversible. In hisconference speech of 2005, Tony Blair, the prime minister of Britainnoted, “Global warming is too serious for the world any longer toignore its danger or split into opposing factions on it"(Theguardian,2017).
Searchfor the phrase ‘’Global Warming’’ in any search engine suchas Google, Bing, and Yahoo and to your amazement you will get oversixty-five million pages of results. Global warming has been asubject of debate that has attracted a lot of attention fromdifferent stakeholders across the globe. What is global warming? Whatare its causes? What impacts does it have on the environment? Whatmeasures should be taken to reduce global warming? These are the mainquestions I would like to address in this my short, informativespeech.
Whatis global warming?
Itis the gradual increase in the earth’s atmospheric temperature.Global warming results in the heating of earth’s surface and itsenvironment including ice caps and oceans (Peters et al., 2013). Theglobal increase in atmospheric temperature has been experienced overthe last few years. The face of the earth temperature has increasedby about one degree Celsius in the last decade. In addition, it isprojected that the global temperature may increase by about 3 degreesCelsius in the next century (Casper, 2013). Although this appears tobe a tiny figure, the trend is worrying.
Manyfactors cause global warming. Some causes are human made while someare natural. Greenhouse gasses are the main cause of global warming(Wang et al., 2016). Certain natural process and human activities areresponsible for the production of greenhouse gasses. The drasticincrease in industries and population has contributed to the releaseof different greenhouse gasses into the earth’s atmosphere.
Anotherleading cause of global warming is the depletion of ozone layer,reduction of the ozone layer over Antarctica. The increasing releaseof chlorofluorocarbon gas has resulted in the constant declination ofthe ozone layer (Casper, 2013).
Theozone layer protects the surface of the earth by preventing harmfulsunrays from reaching the earth. Currently, some harmful sunrays areentering the biosphere. The greenhouse gasses absorb these rays thusincreasing global warming (Haldar, 2012).
Whatare the effects?
Globalwarming is linked to the drastic change of the world climate such asdecreasing winter season, jet stream, increasing summer season,shifts in air circulation patterns, melting ice caps, increasingtemperature, drought, flood, cyclones, heavy storms, and othereffects (Haldar, 2012).
Whatmeasures should be taken to reduce global warming?
Wecannot repair the already destroyed part of the ozone layer. However,we can minimize or prevent its further depletion. We need to reducegreenhouse gasses emission to the atmosphere and adopt the laidprograms aimed at minimizing the effects of climate change. We shouldresolve to use clean energy such as the wind or solar energy (Peterset al., 2013). Reducing the use of petroleum, and coal in industries,and replacing it with electricity can reduce the global warming. Weare also encouraged to plant more trees and avoid deforestation.
AsI conclude, I urge you all to join hands to address this issue beforeit destroys the earth. Global warming is grave issue if assumed canultimately destroy the earth. Thank you.
