**5. Conclusion**

Earth is facing the global warming. Scientifically, there is no longer any doubt that the surface temperature of land, sea surface temperature, and sea levels are increasing. The logical reason of this increasing trend is far beyond the occurrence of natural cause. Despite the different propaganda between the global warming and climate change denier and the advocates, it is of paramount importance to heed for the interest of the humanity and survival of humankind. There is still considerable confusion regarding the exact timing and scale of global warming, as well as the impacts that would result from it, although this is also due as much to human responses to the issue as it is to scientific uncertainties. Growing temperatures, changes in rainfall levels and seasonality; increased frequency of severe weather events such as droughts, floods, and hurricanes; sea level rise; melting of polar ice and glaciers are only a few of the consequences that can be expected. Desertification, loss of tropical forests and coral reefs, decreases in agricultural production, extinction of species, water scarcity, increasing natural disaster losses, and the spread of tropical diseases are likely to be among the ecological and human effects of these changes. Whether the severity of these impacts results in only a slight deterioration in environmental quality and social well-being, or a truly catastrophic collapse that leads to famine, mass displacement, and resource wars, will be determined by how we behave in the coming decades, as well as the probability of an unanticipated response within the climate system to rising temperatures and greenhouse gas emissions.

The polarity of the views with regard to the urgency is demystified by a study in China [28]. The authors reported that on the global scale the average public concern about the GWCC among Chinese citizens are relatively low, further analysis revealed that youth and women with greater post-materialist values had more concern about GWCC than that of their counterparts. Likewise, citizens from provinces with higher economic dependency on carbon-intensive industries were found to have less concern about GWCC than people from provinces with lower carbon dependency. Their study revealed the underlining motive of the GWCC deniers and skeptics. Perhaps, the polarity in views between two school of thought has much to do with national or regional benefit than the actual truth.

Skeptics of global warming are not very convinced of the fact that the change in the climate and the extreme climate, periodically experienced, are the result of the effect of global warming, enraged by the production of greenhouse gases like carbon dioxide. However, they are also equally not able to disregard the voluminous literature which suggests that the climate change is primarily linked with the global warming. Understanding the climate change in totality is sophisticated, owing to the number of players involved in it, which aren't yet fully understood by the experts themselves.

However, the existing literature suggests based on the evidences of increase in the *surface temperature, sea surface temperature, borehole temperature, and sea level*,
