1. Introduction Global warming is moderate increase degrees of the earth’s troposphere generallyattributed to the greenhouse effect caused by enlarged level carbon dioxide(CO2), chlorofluorocarbons(CFC),and other pollutants exist. For example, as the development of industryreleases more garbage, it pollutes the environment. As the result, the earth’stemperature gets 0.
8°C warmer than one hundred years ago and temperature will continue to increasesin the future (Bradfordand Pappas, 2017).Since then, people suffer more natural disasters like drought, flood, tsunami, earthquake. Inaddition, Nature is also subject to much damage, Total 63,837 species whichrevealed 19,817 species are threatened with extinction (Red list,2012). Moreover, temperatures rise to make a difference to marine, andexpanding the desertification.
This paper, based on secondary research, withthe aim of raising people awareness global warming, and will discuss thecauses, the effect, and the solutions to this problem.2. Discussion offinding2.1.Some facts about global warmingAt present, the Earthis becoming increasingly hot.
This phenomenon changes in the planet such asenvironment, weather, animal, erosion and people’s life. For example, Ice in theNorth Pole is melting, Until June 2016, ice square in there decreases 1.5million square kilometers (from 12.7 km² to 11.1 km²).
(For the first time in 100,000 years, the ice inthe Arctic could melt completely, 2016). That is the main cause of the decline of the polar bear. In 36 years, this specieshas declined 13.4% per decade from 1979 through 2015.
Future warming isprojected to be highest in the Arctic, well above that of the projectedglobal warming (Polar Bear: WWF Wildlife and Climate ChangeSeries, 2017). In addition, 2016 year has become the hottesttemperature year in the history. Many disasters occurred in 2016. Especially, alot of droughtsspread across much of southern Africa, triggering local food and watershortages that affected millions of people. Wildfires in North America burnedabout 8.9 million acres of western Canada and the United States, including that a particularly destructive fire inAlberta forcedmass evacuation and destroyed 2,400 homes. In addition, Coral bleaching in theGreat Barrier Reef can be died off by warm waters in the Pacific. (Plumber and Popovich, 2017).
Therefore, Globalwarming affected not only people’s life but also the Earth’s environment. Sincethen, humans must work together to minimize damage caused by global warming.2.2.Causes of global warmingFirst of all, main cause of globalwarming is due to an increase in greenhouse gases (carbon dioxide,chlorofluorocarbons, and other pollutants exist), those gases cannot get out ofthe atmosphere where they are concentrated on them, causing the sun to shine onthe Earth, the heat trapped causing the temperature of the Earth to rise. Inaddition, those gases derived from a variety of reasons such as natural andhuman.
Activities of natural are one of the factorscontributing to global warming. In fact, kind of natural phenomenon releases a huge amount ofgreenhouse gases into the atmosphere. For example, disasters such as forestblazes, volcanoes emit carbon-filled smoke,the plume of ash andsmoke goes out into the atmosphere. In addition, water vapor is present in theatmosphere and has a strong effect on weather and climate, since water vapor isa type of greenhouse gas, so more water vapor in the atmosphere leads to moreglobal warming. Moreover, the grayish-black grime that coats urban buildingstraps and holds nitrous oxide, it also releases it concentrated amounts whenthe sun warms the grime (Sonia Madaan, 2016). It can be seen thatglobal warming is a natural phenomenon of the Earth.
On theother hand, if natural causes to create globalwarming, human activities have accelerated the process of global warming. Especially,Activities such as burning fossil fuel, farming, deforestation generates largeamounts of greenhouse gases. For example, Australia has the levelof CO2 pollution per person is nearly double the average of other developednations and more than four times the world average by 73% of their electricitycomes from coal burning and 13% from burning gas. Besides, this country’sagriculture with livestock are grazed at a large scale contributes 16% of ourtotal greenhouse gas emissions. In addition, Plants play an important role inregulating the climate, but up to one-fifth of global greenhouse gas emissionscomes from deforestation and forest degradation. (Causes of global warming, 2017). According toresearch results, “In the period 1994-2010, total greenhouse gas emissions inVietnam (including LULUCF) increased rapidly from 103.
8 million tons of CO2,equivalent to 246.8 million tons of CO2. Equivalent, in which the energy sectorgrew the fastest from 25.6 million tons of CO2 equivalent to 141.1 million tonsof CO2 equivalent and also the largest emitter in 2010.” (UNDP – Human Development Report, and Vietnam’s first announcement ofthe United Nations Framework Convention on Climate Change, 2007/2008).Consequently, global warming is mainly caused byhuman impacts on the environment and nature.2.
3. Effects of global warmingAt the moment, global warming is becoming more and morecomplex and unpredictable. The Earth’s temperature rising lead to many naturalphenomena unusual. A lot of disasters occur more frequently with stronger intensitythan before. For example, in 2017, Vietnam suffered 16 typhoons and 6 tropical depressions,more than in 2013 (with 13 typhoons and6 tropical depression) (TranQuang Hoai, 2016).
Since then, humans see clearly is the change ofenvironment, weather and influence of global warming.Global warming affects not only human’s life but alsoerosion, animal’s life. Especially, ice is melting worldwide, and the Earth’spoles, where phenomena are the strongest.
Moreover, ice sheets covering WestAntarctica and Greenland, and Arctic sea ice are melting. As the result, thesea level has been rising more quickly than the last century and habitat ofspecies of animal decline sharply. Therefore, animals such as penguins onAntarctica where their numbers have fallen from 32,000 breeding pairs to 11,000in 30 years, and some butterflies, foxes, and alpine plants have moved tofarther north or to higher, cooler areas. From the mid-1980s, with less ice on which to live andfish for food, polar bears have gotten considerably skinnier (Effects of Global Warming, 2017).
Besides, if these effects continue to occur, perhaps a lot of animalsand ecosystems on Earth will disappear forever.Moreover, those disappearances causean imbalance in the ecosystem, and it also directly affects humans. Global warmingis the cause of natural disasters all the world. Especially, double disasterstsunami and earthquake in Japan in 2011 had 16,000 people have been killed,more than 2,000 missing and at least 3,200 dead in evacuation. Until now,nearly 230,000 people are still living in temporary and only 19 percent of the30,000 public houses have been built (Thoa Pham, 2015). In addition, having a variety of stronghurricanes was created by abnormal weather condition, they cause severe damageto the humanbeing.
For instance, in 2013, Super Typhoon Haiyan landed in thePhilippines.Consequently, more than 16 million people were affected, 6,000 death toll, 4.1million displaced and 2.5 million missing. Moreover, not only typhoon Haiyanbrings about the damage to people that this stormy destroyed 1.
2 million homesand half that was completely destroyed. The number of homes lost in theaffected area is upto 90 percent (AlyssaCogan, 2013). Since then, it is not surprising that effects of globalwarming have become increasingly apparent, and these effects are bestmanifested in natural disasters and unusual weather conditions. If human does not have a solutionto this problem, they will destroy not only species of animals and ecosystem ofEarth but also human’s life and civilization.3.
ConclusionOver a relatively period of time,global warming is having a clearer impact and it has become one of the mostconcerned phenomena in recent years. Because both natural and human isthe factor that promotes the rapid increaseof temperature in the Earth. Natural phenomenon as forest blazes, volcanoes,…as well as the consequences of industrial development and the living of humanlife released a large of greenhouse gases.
As the result, people and the Earthmust suffer many transform of environment, climate, and it leads to manyspecies of animals and plants extinct due tothe disappearance of ecosystem,and humans suffer life and property damage. Therefore, people must takemeasures to minimize the effects of global warming, and a small act of eachperson also can change the future of all the world.
