Consequences of Climate Change at World Level: a Theoretical Review

Abstract

IPCC defines climate change as any “change in the state of the climate that can be identified (e.g., using statistical tests) by changes in the mean and/or the variability of its properties, and that persists for an extended period, typically decades or longer. It refers to any change in climate over time, whether due to natural variability or because of human activity” (IPCC, 2007a, p. 30). Climate change phenomena is very threating which impacts the lifeforms and our livelihoods on this earth. The world has been experiencing frequent extreme environmental conditions. This phenomenon is not a frequent/instant event, it is a consolidated outcome of so many years due to anthropogenic and natural causes. The present paper reported the various causes and consequences of climate change at the world level. In fact, many organisation/committees/conferences were established to overcome the adverse effects of climate change and for the survival of the living organisms, respectively. Secondary data is used to identify variability of climatic features and the same information from various reports, research articles, and other sources. This review is an assessment of climate change phenomena at the worldwide level. It is found that the government participation is necessary for the development processes. There should be some rules and regulations for developed and developing countries to overcome the variability of climate change. To sum up, mitigating the impacts of climate change must be of the utmost importance, and hence, this global threat requires global pledge to report its horrible consequences to safeguard global sustenance.
