The microbial aspect of climate change

Abstract

Global warming and climate change are the most prominent issues of the current environmental scenario. These problems arise due to higher concentration of greenhouse gases in the atmosphere which exert a warming effect. Although much attention has been given to anthropogenic sources and impacts of these gases, the significance and implications of microorganisms have remained neglected. The present review brings to light this overlooked aspect (role and responses of microbes in this context) in both terrestrial and aquatic ecosystems. Through existing literature, it attempts to assess the mechanisms that cause microbes to emit and absorb greenhouse gases. The consequent effects as well as feedbacks have also been studied. It was then found that microbes play a major role with respect to climate change. Thus, microbes should never be deprived of their due importance in climate change models as well as discussions on the matter. In addition, the review also identified the necessity of proper research in this aspect as there is a lack of adequate understanding on this facet of climate change.
