The Fourth IPCC Assessment Report shows high confidence that the world is warming. Small island countries, developing countries and Least Developed countries remain most vulnerable to the impacts of climate change. For countries like the Marshall Island, with atoll islands situated just a few meters high from sea level, any uncontrolled sea-level rise has the potential to submerge land areas. Furthermore, climate change impacts could include increased tropical cyclone activities and coastal erosion. Coral bleaching and ocean acidification due to warming also have the potential to affect tourism, fisheries and agriculture, and the ability of the corals to regenerate. Sovereignty claims over natural resources and territory could increase, as maritime zones shrink due to the ambulatory nature of baselines.
The problem of climate change refugees and resettlement also pose challenges. Competition for scarce marine and natural resources could intensify, leaving countries like RMI - in dire straits. Loss of maritime zones, domestic, regional and international security, population migration and resettlement are issues closely tied to the impacts from a changing climate.
Ambulatory nature of baselines/ Loss of Maritime Zones
Though not indicated in UNCLOS, scholars such as Rayfuse, Caron and Soon have concluded that baselines are ambulatory. Thus, when baselines move, the outer boundary of the maritime zones (territorial sea, contiguous zone and exclusive economic zone) also move. Applying this theory, all coastlines and conversely maritime zones of states affected by sea level rise would move. That change would be most acute for low-lying states facing inundation.

They note that without coral bleaching, reefs would possibly be able to grow apace with rising sea-levels, but they are not expected to be able to sustain themselves with the combined impact of projected sea level rise, projected increases in bleaching episodes, and with the additional stressors such as increased land-based sources of pollution and increased atmospheric concentration of CO2.

Coral Reefs are said to be the “tropical rainforest” of the sea. They are home to over 25% of all marine life (http://coralreefalliance.org.stories/storyReader$77). Over the past few decades they have been subjected to destructive anthropogenic practices. Some of the major threats to coral reefs include sedimentation, water pollution, harmful recreational activities, and global warming. All of these things cause stress on corals and can potentially cause mortality. Corals are made up of two parts, a polyp and zooxanthellae. A polyp is a calcerous body that grows from a hard part of the ocean floor. Zooxanthellae is a photosynthetic algae which lives in the polyp and provide energy for themselves and the coral. In many cases, corals undergo “bleaching,” which is a process where corals lose the zooxantheallae or chlorophyll pigment, and turn white (Wilkinson et all). After bleaching corals can survive for several months. It is possible for corals to recover by hosting more zooxantheallae, but it can take between 5 and 50 years for them to recover completely (Wilkinson et all, 1999).
This website gives a large historical overlook and possible conclusion to the issue of coral reef bleaching. Since the 1980’s episodes of coral reef bleaching and death have occurred almost every year in one or more of the world's tropical or subtropical seas. Bleaching happens in episodes, with the most severe typically accompanying coupled ocean–atmosphere phenomena. Bleaching episodes have resulted in loss of coral
Climate change is on the international policy agenda primarily because of warnings from scientists. Their forecasts of a potentially dangerous increase in the average global temperature, fortuitously assisted by unusual weather events, have prompted governments to enter into perhaps the most complicated and most significant set of negotiations ever attempted. Key questions - the rapidity of global climate change, its effects on the natural systems on which humans depend, and the options available to lessen or adapt to such change - have energized the scientific and related communities in analyses that are deeply dependent on scientific evidence and research.
Nowadays climate change is the biggest problem of the human being. It is already happening and represents one of the greatest environmental, social and economic threats facing the planet. Climate change, also known as global warming is the seasonal change for a long geological period of time in the world that is attributed directly or indirectly to human activity, altering the composition of the global atmosphere. Australia faces significant environmental and economic impacts from climate change across a number of sectors, including water security, agriculture, coastal communities, and infrastructure.
With the rising sea level it has already submerged a northwest island in the Hawaii region. This island goes by the name of whale skate. This island has disappeared and the rest of the islands up in that region are at steak for being under water. The islands are housing wildlife that are found nowhere in the world except these islands and most of these animals are endangered.
The vulnerability of fast growing corals as they are bleached has environmental consequences. Corals that are more vulnerable to bleaching are those fastest to use space to colonize and only live for a short period of time. These corals dominate any open space and put slower growing species to death. It’s been thought that bleaching influences the diversity of coral reefs by preventing the more aggressive corals from taking over (Marshall and Baird 2000).

Some islands right in our backyards are slipping away before our eyes. According to Conservation International the concentration of carbon dioxide (CO2) in the atmosphere, as of 2016, is the highest in 3 million years. Global warming will melt many Glaciers that will affect sea level and the Islands around the world including the Chesapeake Bay. Many Islands will no longer exist due to sea level rise and flooding’s. Global warming is when the temperature gradually increases, generally accredited to the greenhouse effect caused by increased levels of carbon dioxide, chlorofluorocarbons, and other pollutants. Pollutants will cause acid rain which will pollute the water and kill off the animals that drink the water.
Due to global warming, the frequency of coral bleaching is predicted to continue to increase (Baker et al., 2008; Spillman et al., 2013) Numerous reefs across the world experience coral bleaching rather than just one reef. Coral bleaching can have a devastating effect on a region 's tourism industry and can cause not only coral mortality, but the death of other animals that rely on coral to survive. Higher ocean temperatures not only result in more frequent coral bleaching, but can increase other threats to the survival of coral. Furthermore, repeated bleaching increases the chance of fatal bleaching events (Baker et al., 2008). Moreover, despite coral surviving higher sea temperatures in the past, there are many other factors contributing to coral bleaching. Coral recovery depends on how often bleaching events occur and global warming increases this and worsens conditions for reproduction which is essential to survival. Coral bleaching due to global warming is more concerning than many people

Climate change has been affecting coral reefs in a negative way. If the climate continues to get warmer more of our coral reef become bleached, the structure of the reefs will become weak, and algae that keeps coral healthy will die. In the essay, “A framework for understanding Climate change impacts on Coral Reefs” by Joshua Clinner (2016), he emphasizes our climate change has become one of the long-term threats to coral reef. The article “Climate change and human impacts are damaging the world’s coral reefs”, which didn’t include an author (2001), states that the sea temperatures throughout the tropics has increased dramatically leaving much of the coral unhealthy. Spencer Hall (2008), discussed in his article “Coral Reefs and Climate Change”, how the increase in climate change puts a lot of stress on coral reefs because they are very sensitive to the change of temperature. Rigel B (2003) states in his essay, “Climate Change and Coral Reefs”, that coral reef has already been negatively impacted by
There is little doubt that the current international regime is not effectively protecting coral. The statistics speak for themselves. 19 percent of the earth’s coral reefs have already been “seriously degraded or lost.” Over 60% are under “immediate and direct threat.” 90% are expected to be at risk by the 2030s. And by 2050, nearly all coral reefs will be in danger.
According to the World Bank Development Report 2013 there has been an increase in global surface temperature of 0.4 to 0.9 Celsius (C) in the past 100 years. This change in temperature largely caused, according to the IPCC, by the release of GHGs through human activities. There are several effects associated to the change in global temperature, mainly affecting ecosystems and populations worldwide. Among these effects or consequences are sea-level rise, drought, floods, loss of mangroves, and the intensification of storms and climate processes such as El Nino and La Nina. Recent studies have focused on sea-level rise and the global effects. Over the past 100 years, sea levels have increased by 10 to 20 centimeters (World Bank, 2003). Moreover, arctic sea-ice has continued to shrink up to 10 percent or more of its total mass and by 40 percent of its thickness. Glaciers and small ice caps are rapidly melting, causing several changes in the flows of rivers and ecosystems, as well as adding to the increase of sea levels. Sea level rise will most likely severely affect unprepared, developing countries and their populations. Concomitantly, developed industrial countries with higher levels of GDP are likely to cope more efficiently with the effects of sea level rise. This paper will focus on the prognosticated socio-economic costs of s...
One of the major effects of global warming is the rise of sea level due to thermal expansion of the ocean, in addition to the melting of land ice. Now there are dozens of land areas that sit well below sea level and the majority of those land areas are very well populated. At least 40 percent of the world 's population lives within 62 miles of the ocean, putting millions of lives and billions of dollars ' worth of property and infrastructure at risk. (Juliet Christian-Smith, 2011) This means if the sea level rises to the projected level of 25 meters (82 feet) half of the world will retreat back to the ocean. (Rohrer, 2007) Also rising sea levels means higher tides and storm surges riding on ever-higher seas which are more dangerous to people and coastal inf...
Climate change is an inevitable phenomenon that is being experienced globally in various forms such as temperature rise. Sea level rise, droughts, floods, hurricanes, landslides, etc. According to the forth assessment report of the IPCC project even with immediate implementation of mitigation strategies global climate change will continue for decades. Climate change is inflicting serious consequences on human wellbeing and will continue to inflict damages in the future. It is estimated that mean global temperature will rise by 1.8 ºC - 4.0 ºC by end of the 21st century (Izaurraade, 2009). A new global climate model predicts that in the coming decade the surface air temperature is likely to exceed existing records (Smith et al., 2007). Growing season temperatures in the tropics and subtropics by end of the 21st century will exceed the most extreme temperature recorded in the history (Battistic and Rosamond, 2009).
