What Is Sea Level Rise ?  

       Local mean sea level (LMSL) is the average height of the sea measured over a period of time. Increase in the water levels of the sea above the Local mean sea level due to global warming and the melting of glaciers and icebergs and excessive rains etc is called sea level Rise.


It is usually caused by the presence of man-made chemicals. Such chemicals can enter the soil through different modes like rupture of underground storage tanks, application of pesticides, percolation of contaminated surface water into the soil, oil and fuel dumping, leaking of wastes from landfill sites or discharge of industrial wastes directly into the soil. The occurrence of soil contamination has strong ties with the extent of industrialisation and intensities of chemical usage. More...


Sea Level Rise Statistics

Sea Level Rise Statistics             We live in the world where the climate is being modified substantially by our activities. These changes lead to various impacts and one of them is sea level rise at an unexpected rate in the last few decades. The climate has changed throughout the earth’s history and in last 400 000 years four glacial cycles have been followed by our climate. Incoming solar radiations time and amount has changed significantly due to this.3 meters per century was the rate at which the sea levels rose 21,000 years ago. The sea levels rose at the rate of only 0.2 meters between 1000 BP to the late 19th century. During the 20th century there was an average increase in sea levels by 0.17 meters.

If we check the statistics since 1900 the sea levels rose to 50 meters above the normal sea level in 50 years by the year 1950. Between the years 1950 and 2000 the sea levels rose at a much faster rate. In the year 2000 the sea level was 175 mm meaning it rose at the rate of 75 meters in these 50 years. From the year 2000 to 2010 it has risen 25 meters meaning if it continues to rise at this high rate the sea levels will go upto 300mm by the year 2050.More...





Global Warming:

Climate-Change-And-Sea-Level-Rise      The term ‘Climate change’ means high degree of change in the weather. It could be the temperature rise or fall. Global warming is the perfect example and consequence of Climate changes. The two gases that contribute majorly to the natural greenhouse warming are carbon dioxide and water vapor. There are other gases that contribute very less as compared to carbon dioxide and water vapor which are methane, sulfur hexafluoride and nitrous oxide. More..
