“…As a result of the coastal areas being submerged by the sea, fast increasing waves have significant effects on them. A place will have to be abandoned if it cannot afford the expenses of putting protection and adaptation measures in place, which would cause social, economic, and environmental losses [13]. In response, research into newer and more unconventional strategies in slowing rise in sea level has increased over last few decades.…”

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.

“…Due to the accelerating rise in sea levels, coastal ecosystems (such as marshes and mangroves) could be lost, exacerbating climate damages. Thus, humanity's primary goal in deploying SRM may not be stabilizing temperatures but holding back the sea (Irvine et al, 2012;Zhao et al, 2017;Wolovick & Moore, 2018;Li et al, 2020;Lockley et al, 2020).…”

“…To reverse SLR, substantial regrowth of ice sheets will be necessary. SLR reversal may require long-term overcooling, perhaps accompanied by targeted interventions to directly manipulate either ice sheets or input precipitation (Lockley et al, 2020). Due to current knowledge gaps in ice sheet dynamics, the speed and extent of possible ice sheet regrowth simulated by models would be highly uncertain.…”

Solar geoengineering, also known as Solar Radiation Modification (SRM), has been proposed to alter Earth’s radiative balance to reduce the effects of anthropogenic climate change. SRM has been identified as a research priority, as it has been shown to effectively reduce surface temperatures, while substantial uncertainties remain around side effects and impacts. Global modeling studies of SRM have often relied on idealized scenarios to understand the physical processes of interventions and their widespread impacts. These extreme or idealized scenarios are not directly policy-relevant and are often physically implausible (such as imposing global solar reduction to counter the warming of an instantaneous quadrupling of CO2). The climatic and ecological impacts of politically relevant and potentially plausible SRM approaches have rarely been modeled and assessed. Nevertheless, commentators and policymakers often falsely assume that idealized or extreme scenarios are proposed solutions to climate change. This paper proposes 18 scenarios that appear to be broadly plausible from political and Earth System perspectives and encompass futures that could be both warnings or perhaps desirable. We place these scenarios into four groups following broader strategic contexts: (1) Global Management; (2) Regional Emergencies; (3) Coordinated Regional Interventions; and (4) Reactive Global Interventions. For each scenario, relevant model experiments are proposed. Some may be performed with existing setups of global climate models, while others require further specification. Developing and performing these model experiments – and assessing likely resulting impacts on society and ecosystems – would be essential to inform public debate and policymakers on the real-world issues surrounding SRM.

“…Governments and donors are now promoting the development of extreme scientific and technological solutions for the express purpose of adapting to climate change and delaying the worst possible outcome (for example, social and ecological collapse). Contemporary examples include unproven technologies such as carbon capture and storage 39 alongside geoengineering and bioengineering stopgaps, such as warm-water berms for glaciers, site-specific solar radiation management for coral reefs, and cryopreservation for temperate forest species [40][41][42][43][44][45] . These illusory forms of so-called radical solutions have received substantial support from fossil fuel nations, industries and organizations 46 .…”
