THE RISING SEA LEVEL 5
TheRising Sea Level
Therising sea level
Overtime, geological aspects have been changing due to a wide range offactors that could either me natural or man-made. Winds and weatherconditions have brought about weathering and soil erosion while humanpractices such as farming, building and construction, landreclamation and other activities have also led to dramatic geologicaland environmental changes. It is clearly evident that climaticconditions as well as weather patterns are not static and this couldbe related to the actual geological changes taking place.
Inthe past, events have been told about the rising levels of the sealevels. As it can be observed, the water levels have gone up over theyears. History provided by the older inhabitants and residence depictthat in the past, water levels were lower. An explanation to thisgeological happening could be global warming that has lead to massmeltdown of glaciers thus increasing the volume of sea water. Inaddition other factors such as the gradual sinking of the surface ofthe earth as a result of movement of earth materials, as well asmining and removal of large volumes of groundwater play a part inthese effects. Furthermore the increase in sea level has otherpossible effects on the frequency as well as the intensity of storms.
Landsubsidence as described above a significant contributing factor tothe rise in the sea levels and the causes of this phenomenon arethose that are somewhat important. A good example is the removal ofhuge water volumes from the underground. Water is necessary for thesurvival of the population, yet in the process of acquiring the same,the resulting consequences are quite astounding. In other words theacquisition of some resources plays a vital role in the movement ofthe earth downwards. This downward movement of land could be avirtual indication of increase of sea level in that, it could bepossible that the sea level has not increased as much but due to thesubsidence the water level could be observed as risen while in thereal sense it hasn’t.
Earthdisturbances bring about potential hazards which if not containedearly, may lead to mass destruction of property as well as loss oflives. Due to this, it is evident then, that foundations of buildingswill most probably be affected. The weight exerted by theseconstructions could also be having an effect on the overall movementof the earth and the subsequent movement compromises the stability ofsuch buildings. This is further exaggerated by the ever increasingneed for the development of land and water resources thus initiatingnew land subsidence problems. The parallelism in this situation issimply the problem. The more the need for water and infrastructuredevelopment rises then the greater the possibility and levels ofearth disturbances and the outcome increases the possibility of highsea levels as well as land subsidence.
Theincrease in sea levels has been associated with severe hazards whichcould happen spontaneously or gradually. Therefore, there is the needto address such possible hazards based on the geological observationsidentified. In this context one cannot fail to notice that apart fromthe rising sea levels, the tide levels as well as the extent of waveuprush on the shores. This situation has some implications includingerosion of bluffs and in the long term complete dismantling of thebluff may occur. This occurrence is quite a big threat especially inhabours and residents who live near to beaches and shores. Inaddition the likelihood for flooding also increases significantly aswell as the possibility of collapsing of buildings.
Thesea level is a good indicator of the past, the present and thepossible future. The study and monitoring of these levels can be ofhelp in order to determine the previous levels, the current levelsand the future outcomes. In addition the effects that are associatedwith this increase such as land subsidence, seiches and storm surgeswhich are tsunami-like phenomenon can be good indicators of thepresent situation in terms of risk to these hazards. It is clear tome that, future prediction is key to the prevention and containmentof hazards in case of sudden occurrence. It is possible that furthercontinuation of such happenings would increase to levels that cannotbe easily contained. The interrelationship is direct, that isincreased activities such as underground water removal and landsubsidence tend to increase the sea level which in turn increaseschances of flooding and destruction of property and loss of lives.
Ageologist or rather I, can therefore be able to utilize theseobservations and use them effectively for the proper and efficientplanning for the control of the effects and ensure that residents,commercial investments as well as other recreational facilities havebeen protected. High sea levels have much more possible risks thanbenefits and since controlling the volume of the sea is a feat deemednext to impossible, then the best way to deal with this phenomenon isto structure out ways that would help prevent occurrence of hazardssuch as flooding as well as reduce the progression of the effectsincluding the erosion of buff especially in habours and areas withresidential settlement.
Asexemplified above, geological facets have been changing a lot. Inthat regard, I learnt how various activities have contributed tothese alterations. For instance, rising sea level is attributed tothe changing ecological temperatures. The changing temperatures aremainly caused by greenhouse gases that are produced when burningfossil fuels. The gases then trap heat in the atmosphere henceleading to global warming. The adverse temperatures lead to warmingof water bodies and since warm water occupies more space than coolerwaters, sea levels rise. I have seen people who reside in someislands relocate fearing floods emanating from the rising sea levels.
Anothervital lesson learnt entails disturbances of natural systems and theeffects to the ecological system. As pointed out by research, thesun’s intensity has never changed. Global warming cannot betherefore attributed to the changing intensity of the sun. However,as I come to learn, disturbances of natural systems are mainly due tohuman activities such as deforestation, combustion of fossil fuelsamong others. Though conservation agencies have been championing useof clean energy like wind and solar, it is not the case with manycountries. Generally, human activities cause most of the changesexperienced in the ecological system.
