“…From 1993 to 2013, the Strait of Malacca exhibited a SLR rate of 4.1 ± 1.9 mm/yr. as revealed by altimeter analysis [85]. Malaysian sea levels have been rising at a spatially variable rate ranging from 1.4 to 4.1 mm/year throughout the period 1993-2008 [86].…”

Tide gauge records and satellite altimetry have demonstrated that the sea level is rising on global and relative (regional/local) scales. Globally, the rate of sea-level rise (SLR) in the past two decades is faster than at any time. During the most recent era, 2006–2018, the global SLR rate was 3.7 mm/year, i.e. nearly three times faster than during 1901–1971 (1.3 mm/year). This is mainly attributed to two main reasons: (1) seawater thermal expansion due to climate change and global warming, and (2) ice melting of the Arctic and Antarctic regions. Additionally, the vertical land movement (subsidence/rise) can impact the calculated relative SLR rates. SLR is projected to continue if global warming will continue. SLR has a destructive impact on coastal cities, especially coastal low-lying areas. Factually, it is not only human infrastructures that are at risk from the SLR and coastal flooding, but also coastal environments such as coastal wetlands, seagrass beds, rocky shores, and sandy beaches are vulnerable to such a rise and flooding. This chapter aims at highlighting the SLR issue on global and relative scales, by using both tide gauges and altimeter tools.

“…Meanwhile, in Southeast Asia (SEA) sea level rise poses a particular danger to an archipelago and densely populated country like Indonesia. [46] conducted a study on sea level in Dumai Indonesia rise between 4.80 to 5.61 mm/yr. Sea levels in the tropical Western Pacific area east of the Philippines rose by 5-7 mm/yr between 1993 and 2015, which is about twice the global rate in rising sea level [47].…”

Sea level rise has currently become a major issue for climate change. It has globally drawn attention because as time passes, global sea levels will continue to rise at an accelerating rate in the 21st century. It will cause a serious impact on environmental problems such as coastal inundation, salt intrusion, coastal erosion, and other phenomena. These scenarios lead to earth problems in which land and oceans continue shifting due to climate change, posing a threat to the very existence of all living beings in the coming years. As a result, climate monitoring is critical for tracking the change. Therefore, this paper reviews the physical factors that contribute to sea level rise. The main contributors for sea level rises, such as ice melting from land into the ocean, thermal expansion, a slowing of the Gulf Stream, and land sinkage, are being discussed. This paper also emphasises the studies of regional sea level, and sea level rate changes. Finally, this review will be discussed in order to clarify the causes of sea level rise issues for human society.

“…Several studies have been conducted, for e.g. [7] on sea level rise and coastal flooding in Dumai City [8]. Taking several explanations from the Open-ended Intergovernmental Expert Working Group on Indicators and Terminology to Disaster Risk Reduction (OEIWG) regarding the definition of critical infrastructure, [9] describes that critical infrastructure is the physical structure, facilities, networks and other assets that provide important services for the social and economic functions of the community, including the following: 1) energy (network/power generation including nuclear, oil and gas), 2) health facilities, 3) educational facilities, 4) transportation infrastructure (airports, ports, stations, roads), 5) government facilities, 6) defense and security, 7) telecommunication networks, 8) water and sanitation service networks, 9) financial services, and 10) agricultural infrastructure.…”

Based on Climate Resilient Development Policies on 2020-2045, there are four priority sectors threatened by climate change, namely marine and coastal, water, agriculture, and health. Indonesia still depends on oil and gas energy that will threats to infrastructures that support the sustainability of production that can have an impact on people’s lifelines. This study investigates the risk distribution shift of climate change impacts in Dumai, which generally have oil refineries and ports. Risk is calculated by using hazard and vulnerability components. A uniform weighting approach is used to calculate each indicator indices. Using the RCP 8.5 hazard scenario with threats in the form of sea-level rise, moderate flooding, and high-end results in the projection year, this research results in significant differences in affected areas and at risk. The main factors affect the increasing of element at risk are the inundation and the spatial changes. An increase in the risk area means there will be an increase in losses. Moreover, disasters in oil and gas cities have the possibility of collateral hazards and even disruption of the national energy system. The government must take several adaptation steps such as adding eco-buffer zones, walls around refineries, and periodic monitoring of critical infrastructure.
