Climate change impact on eco-biology and socio-economy—A concise discussion

Abstract

Global scientific community has a near unanimous consensus that anthropogenic emission of greenhouse gases and thus their rising atmospheric concentration are causing global warming and other climatic changes. According to the IPCC, global average annual mean surface air-temperature is projected to rise between 1.4 and 5.8 °C by 2100. This rise in temperature will impose various climate related incidents like drought, forest fires, typhoons, more intense hurricanes, and frequent storms. Due to the decrease in air quality, human health related problems in future will be catastrophic. Considering the present climate trend, climate scientists are speculating that new ecosystems will be emerged and existing ecosystems will be wiped out in future and this shift in biomes will be irreversible. The multivariate factors of climate change are supposed to have an effect on all the levels of biodiversity, starting from organism to biome levels. Not only ecosystem destruction but also climate migration is a major issue at present because this migration is directly impacting the socio-economic profile of many countries. Many governmental and non-governmental organisations have predicted that a billion people may be displaced by 2050 as a result of environmental causes, and climate change will be one of the major contributors. It has been found that people are less bothered about climate change and this issue is in their lowest priority list as people think they are not personally responsible for climate change and has seen climate change as a global effect. Ignorance and greed of the people sometimes leads them to violate the natural/environmental rules and as a result negative consequences of climate change are the obvious outcomes of these unethical activities.
