Topic: Key Impacts on Sea Level Rise on the Small Island
Sea-level rise highly impacts on entire coastal areas with different-different extents. It
indicates a major ongoing change of climate at global level, especially for small island states. It
has been estimated that level of sea rises continuously with constant annual rate of about 0.05 m
(Latai‐Niusulu, Binns and Nel, 2020). The physical impact of such rise results is disappearing of
the low-lying islands; submerging and increasing flood conditions on coastal land; increased
erosion; and so on. However, climatic change and socio-environmental implications are
uncertain, but vulnerability of low-lying island states towards hazardous events, is more likely to
increase significantly. In this regard, considering the uncertainty of global warming and climatic
changes as well as its implications, a report is being prepared, to analyse vulnerability of small
islands due to natural hazards especially, rise in levels. For this purpose, IPCC Third Assessment
Report (TAR) is critically evaluated under present essay, which entails similarities shared by
small islands that reduces resilience towards climatic variability of them.
A rise in the sea-level continuously on its own, indicates that people are experience more
frequent and extreme sea-level events, which is rise above the estimated fixed reference point.
However, variation about the mean doesn’t change, but frequency of this extreme events has
increased various times, even for modest changes within mean sea level (Hafezi and et. al.,
2020). Over the twenty-first century, it has estimated that sea-level events extremely have risen
by near about 0.5 m, where most of the locations of islands of Australia has good tidal records,
from last thirty years. But due to last few years, sea-level rise is more likely to increase with high
frequency especially in the areas of Brisbane Sydney, Bass Strait and more. Furthermore, as
tropical cyclones have become more intense as per IPCC report, so, it has brought higher storm
surges with cyclones, that directly affect the extremeness of sea-level, especially in northern
parts of Australia (Hil, 2020). In addition to this, it has also analysed that tracks of such storms
may also move towards south poles from north, which may bring changes in surge and wind
events around the southern Australia.
Rise in sea-level usually leads to erosion as well as causes shoreline for retreating landwards
or shoreline recession, around sea areas including sandy coasts (McGregor and YERBURY,
2019). It has estimated that around 70% of beaches of entire are eroding, where less than ten
percent are extending seawards. So, it has indicated that shoreline recession is happened with
100 times more rate then rise in amount of sea-level. So, it equates that around 50 m erosion of
