The term “global warming”refers to an abrupt increase in the earth’s temperature, beyond the tolerablelimit.
Both human and natural causes might be accredited for the rise in theglobal surface temperature. This issue has become a major concern, worldwide. Thegradual rise in the Earth’s temperature leads to melting of ice-caps in the PolarRegions. As a consequence,the earth’s water level increases beyond the optimal level. That poses lifethreat.
Extreme heat causes a violent disruption in the Earth’s ecologicalbalance. The ecologists and the biologists of the major nations have gonethrough an in-depth research work and analysis to find out the actual causesand possible outcomes of global warming. This would also help us to reverse theprocess of warming up.
“Thetruth is, as most of us know, that global warming is real and humans are majorcontributors mainly because we wastefully burn fossil fuels”- David Suzuki. Thuswe see that the human activities might be primarily held responsible for thisdrastic change in global temperature. There can be enormous causes that mightlead to this problem. Our planet iscovered with a blanket of gases which keep the earth’s atmosphere warm and enablessustenance of lives on earth. Now this blanket of gases is getting thicker dueto the deposit of greenhouse gases-released due to burning of fossil fuels,used in energy production, electricity and transport (Hardy, 2003). The majorgreenhouse gases are Carbon Monoxide, Methane and Sulphur dioxide.
Theseharmful gases do not allow the heat to radiate out of the earth’s surface whichinvariably raises the temperature. The major source of greenhouse gas emissionmight be volcanic explosion. A huge amount of CO2 might be released from asingle volcano, which raises the temperature to a high level. Again the heatcannot escape the, it gets trapped within by the greenhouse emissions. Methaneis also an important greenhouse gas that can hold back approximately 25 timesmore heat that CO2. Cattle dungs, landfills, natural gas, petroleum extractionprocess, coal mining, mobile explosion, or industrial waste process are thepossible sources of methane gas formation.
Since the origin of human species, we have undergonedifferent stages of evolution that have brought about major transformations inthe earth’s constitutions. For the sake of living and inhabitations, the humanbeings have resorted to cutting down of trees to make land for houses andbuilding. For the sake modernization, we have almost depleted natural resourceslike coals, oil and petroleum (UK, Essays, 2017). The industrial revolution and hugetechnological development have led to deforestation, burning of fossil fuels,mining, carbon emissions, automobile emissions and pollutions which haveviolently disturbed our ecological balance to a considerable degree. The trees andother greeneries around us are the only source of oxygen for all the livingbeings, on earth. Reckless cutting down of trees, lead to the crisis of thismajor life saving gas. Besides, the level of poisonous gas like CO2,CO and methane are increasing everyday due to atmospheric pollution (Hardy, 2003).
The leading greenhouseagent in the US is gasoline, the burning of a single portion of which mightproduce more than 20 pounds of CO2. Burning of oil, coal, petroleum isthe primary origin of fossil fuels. The extraction of oil and petroleum inmines and industries produces huge amount of such pollutants which destroy theatmosphere, gradually. The burning of coal for electricity is the one of theprimary contributor of fossil fuels. As per the report of International EnergyAgency, coal is the base material of half of the electricity produced andconsumed in the US and the rest of the world (Biello, 2007). This is increasing at an alarming ratewhich jeopardizes the living conditions.
The worst situation is that we don’thave any better alternative to coal, for producing electricity and help intransportation. This is because the close substitutes, nuclear power, emitradioactive wastes and carbon neutral biofuels might lead to elimination offorests which consequently causes deficit in the food supply.The industrialized nations are worst affected by theeffusion of poisonous gases like CO, CO2, ethane and methane; from automobilesand the outlets used in factories and industries. These carbon emissions arethe causes warming up of the global temperature and deterioration of lives onearth. In the UK around 45% of our carbon emissions come from business houses,around 30% are from vehicles and 25% are from household activities (Hardy, 2003). The atrocity ofthe situation could be severe for the existence of human and animal lives.
Itcan even lead to extinction of lives on earth. As a result of this, thetemperature increases. It makes the planet unfavorable for lives. The depletionof forests leads to soil erosion which might trigger off land sliding andearthquakes. Apart from rising temperature, these denizens of pollutants mightcause serious health issues related to respiratory problems, thus affecting theliving condition of the people. Hence, deforestation should be minimized;afforestation should be encouraged. The glaciers are fast disappearing; sealevels are rising, seasons changing, coral reefs dying and extreme weatherevents becoming more pertinent.
The impacts of climatic change are alreadyresponsible for killing an estimated four lakhs people every year and damagingour biodiversity (Scottish Environment Protection Agency, 2017).The extreme rise in the Earth’s temperature might lead to various healthhazards. The melting of ice-caps, loss in biodiversity, and collapse of humanand animal lives are the major after effects of global warming.
The increase inthe rainfall and excess of humidity in air might pose a threat to certainanimal and plants. Diseases become more apparent. As temperatures goes up,condition of drought has increased in the U.S.
The whole forests have begun todisappear including tens of millions of trees in Colorado’s Rockies. As theoceanic temperature rise, the occurrence of hurricane becomes stronger and thatbe severe for the costal nations. The increased occurrence of flood is a commonconsequence of global warming which would destroy crops, harvest, cattle andhuman lives. The diabolicaleffects of the global warming deserve immediate attention. The solar energy, thewind energy, the tidal energy are the best alternatives to the greenhousegases. A proper power grid system might be installed to trap energy from theseinexhaustible sources of nature. Installation of biogas plants might bereplaced with coal economy. This would help cut down greenhouse gases, and arecost-effective and boost up the country’s economic growth.
Petrol drivenvehicles should be replaced with vehicles run on LPG or biogas. The use ofgasoline might be replaced with biodiesel. Hybrid vehicles, cycling, walkingare good alternatives to cars run by gasoline (Biello, 2007). Recycling is a good approach toreducing global warming. The plastic materials, bottles, papers might be convertedin re-usable substances. This prevents the wastes of potentially usefulmaterials, which might lower the greenhouse emissions. Certain human practiceslike switching off electricity when not in use, planting of trees around yourhouses, proper disposal of wastes, use of energy saving products, woulddefinitely lessen the release of CO2 in the atmosphere.
The agencies likeUNFCCC, Kyoto Protocol, European Climate Change Programme, the Department ofEnergy and Climate change, committee on change, climate change Scotland Act2009, are some of the government regulations, strategies and organizationsthose are playing a major role in carving greenhouse effect; thereby globalwarming (Scottish Environment Protection Agency, 2017). Even a commonhouseholder might convey the concerns regarding global warming in the ScottishGovernment website or Greener Scotland. “Global warmingis a fact. Now it’s up to liberals to make it a reality. Hence there is crucialimportance in preventing powerful, greedy free market forces from getting inthe way of worsening storms and rising sea levels. The Kyoto Accord is goodfirst step”- P.
J. O’Rourke. Hence this is the crucial time that we fix ourattention on this issue with wartime emergency. If we consume less and concernmore that might help a lot to save our planet from the diabolical effects ofglobal warming.
