Abstract

Because of extreme heat during the last few years, absorption of heat in ocean water is continuously on the rise and due to additional melt water from icebergs the phenomenon of sea level rise is gradually coming to an alarming level. The present scenario based on the proposed mitigation measures to restrict the rise in temperature hardly commensurate with the decisions in Paris Agreement. Currently although geo-engineering, which is a mechanism to limit extraordinary sea level rise, has attracted scientific interest as per the current state of drastic changes in climate change, standard mitigation measures may not be enough to stop sea-level rise. This paper examines the various approaches. and options under Geo-engineering and compares effectiveness of traditional and modern geo-engineering techniques vis-à-vis other conventional mitigation measures. It is opined that conservative and groundbreaking techniques can decrease the ongoing rise in sea-level, however most befitting results would be accomplished through the combination of approaches.
