Our World, Our Climate
Our World, Our Climate
The rise of water levels in our oceans is mainly due to the increased temperatures throughout the world caused by the effect of global warming, due to the gases such as carbon dioxide destroying the layer of ozone which protects the earth from the sun's powerful rays
Although there are other reasons. Global warming has also caused the ice caps to melt, and as these melt into the water the sea's volume becomes larger and therefore increases the sea level.
Such places where the ice is begining to melt are the glaciers in Greenland and the Arctic. but scientists are of the opinion that thermal expansion is the most significant factor.
Scientists have found that the global average sea level will rise by three millimetres (this estimate was made by the IPCC the intergovernmental Panel on Climate Change). This rise is expected to increase, and by the end of the century the world's average global sea level could rise by anything from twenty eight to forty three millimetres.
The estimation varies from place to place due to the different land deposits and form of the sea bed which could also change the sea-level.
A rise in water will create many problems for the coastal life,this includes not only the wildlife but the people who live there.
The dangers that they face could include wave attack and flooding which can be caused by a rise in the sea level. One such place that could possibly suffer such dangers is Bangladesh. Any sea level rise could cause this area to be submerged .
The ecological aspects that could arise from sea level rises could well be a large reduction in fresh water due to pollution and its increased salinity, making it too salty to be drunk without filtration. This could also affect crops and cattle which would result in a decrease of local resources and could make it harder for growing crops. Together with the added fact that over two thirds of the country's population works in the agricultural sector harvesting plants for export to earn money.
Rice is the main crop grown across Bangladesh, a sea level rise could devastate this industry. Rice is its main export and the yield would be greatly reduced due to lack of available land.Over half the population rely on the local industry for their survival.
Fishermen who farm shrimps would benefit from an increase in sea water on their land. Shrimps need salt water to live and with an increase in salinity the water would reach the required levels for an increase shrimp farming. This would actually provide job vacancies and there would be more opportunities for people who farm shrimps.
Most people living in rural areas make their living from the sea. Approximately, that is one million fisherman work who full time and eleven million work part time. However these figures take into account fresh water fishing, and with the salinity increase, sea fish could become a smaller resource.
The social implications for people who live by the coast, means that they would have to move out of their homes in order to continue working and to find new homes. With many people moving at the same time this could create major problems, particularly with the estimated one million people that would have to be moved due to the possibility of floods.
It is important to take into account that if no action is taken, then an area such as Bangladesh could easily lose thirteen percent of it's land due to flooding from sea level rises. This would cause a estimated thirteen million people that would need to be rehomed.
An environmental issue due to the increase in sea levels could be the salinity increase of the soil and rivers at the coastline, which would make the area almost inhabitable making the land's soil too salty. An increase in salt water would greatly affect the survival of the animal life and freshwater fish.
