Climate Change and Rising Sea Level

A new threat to global security is now becoming the point of attention among world leaders, calling all nations worldwide to cooperate and be part of the solution instead of adding more weight to this serious problem. This new threat of global security that will bring the world to doom, if not further contained, is climate change.

Mother Nature is finally doing its strike.  It is not new to many that climate change has now become one of the most potent threats of global security as it remains irreversible despite the endless efforts painstakingly exerted by world leaders just to contain the havoc brought by it.  The creation of the Intergovernmental Panel on Climate Change is one great manifestation on the concerted efforts of member countries of the United Nations (UN) and the World Meteorological Organization (WMO). IPCC primarily focuses its research and analysis to the deeper understanding of the threats posed by climate change and how such can be prevented to further damage the world.

One of the ill effects of global warming and climate change which is giving utmost focus by some nations today is the increasing sea level which, according to experts, will eventually bring some nations to sink.  According to the IPCC report, an increase in sea level by 19-58 cm by 2100 is highly possible with the ongoing problem of global warming and climate change. Furthermore, the continuous melting of polar ice hastens the increasing sea level with Antarctica’s polar glacier projected to contribute 60-meter of the sea level rise if melted entirely, and Greenland to contribute 7-meter in the global sea level rise.


What are the effects of rising sea level?

Some might not consider the rising sea level, for the meantime, as threatening because they have not yet felt the full-bloom catastrophe brought by it.  But experts and scientists have considered the rising sea level as something not an imminent threat anymore as such an occurrence is happening already in some parts of the globe.  The rising sea level can put many land areas below sea level as such can be construed by the intense flooding incidents in some areas even with just a slight rainfall, bringing many people homeless. This also badly affects the agricultural sector of a place since floods can destroy root crops and other agricultural products, which serve as sources of income by many people residing thereat.

Increasing sea level also adversely affect coastal areas as coastal erosion and inundation are now prevalent in island countries worldwide.  This, in return, will have a negative impact most especially to developing countries where its residents mostly rely on fishing and marine resources as their source of income.  Another cited bad impact of rising sea level is the intrusion of salt water to the waterbeds which, in effect, salinates the groundwater.  This will have a major effect in the long run as groundwater serves as the major source for drinking and other domestic uses by humans. Furthermore, intake of salinated water will adversely affect the health of the one drinking it.

Meanwhile, some areas in the world that are deemed to be in sinking due to rising sea level include: Bangkok, Thailand; Kiribati in the Pacific; Philippines; Japan; Egypt; India; Vietnam; Dhaka, Bangladesh; Jakarta, Indonesia; and some parts of USA such as New York and Los Angeles.
