Ice bergs are melting,water level throughout the world is increasing, natural habitats are beingdestroyed and to make things worse, flora and fauna is struggling to stayalive. Over many years of countless researches, it is becoming obvious that wehumans are the reason why Earth is becoming hotter and hotter. It is us,humans, that have provoked the past century’s increase in the temperature ofthe Earth, by emitting heat-trapping gases. But why are we humans to be blamedfor the gas that we did not release? In order to fulfil our needs, wants anddesire, technology has developed in such a way that our life is much easier nowcompared to the olden days.
Today, we hardly have to do any work. Most the workis already automated while we just have to keep an eye on the machines whileour work is being done. We can see the direct and obvious results of using suchgadgets but little do we know that these appliances are the ones that areactually killing us. These appliances release harmful gases that will not onlybe trapped in the atmosphere, but will also cause us to suffocate one day. The ultimate result of this is global warming. Globalwarming is used to outline a gradual bloom in the average temperature of Earth’ssurrounding which will eventually cause climate change.
In simpler words, itcan be said that global warming is the rise in the average temperature of theEarth’s atmosphere. There used to be debates and quarrels among manyorganisations, claiming that there is no such thing as ‘global warming’. However,scientists have conducted numerous observations, researches and experiments andhave come to an agreement that indeed, Earth is getting warmer day by day. Somephenomena that correspond to this statement is that the temperature of the seahas risen, ice bergs in polar regions of the world are melting fast, sea levelis rising rapidly and the air is getting drier and drier.
Earth’saverage temperature has increased by 1.1 degree Celsius compared to how it wasin the 19th century. This rise is caused by the amount of carbondioxide in the atmosphere as well as human activities that promote the releaseof heat into the air. In statistics, most of the warming in the climate started35 years ago, which is just getting worse and worse as the day passes by.
Adding to that fact, NASA has declared 2017 as the second hottest year in the worldsince 1880 and the top 5 hottest years in their records are awarded to yearsafter 2010. A statistics graph, Figure 4.0 has been included in the Appendicessection to compare the global temperature since 1880.
