can global warming rise the the sea level , we live nr coastal area in india , how many years it will take ?

Answer 1

yeah its true that sea level rises due to global warming becoz due to it the polar ice caps n the glaciers melt rising the sea level .
According to the latest studies by the scientists it will take 40 yrs for the polar ice caps to melt if the rate of global warming goes on at this rate

Answer 2

Interestingly, in the past century, sea levels have risen at about the same rate as they did between 1400-1850. Since there was no large scale industrial activity and thus no human-caused global warming before 1850, this should immediately lead us to question the hypothesis that global warming is causing sea levels to rise. Further, the climate warmed sharply between 1900-1940, and actually cooled between 1940-1975. The data show that the sea level rise *slowed* during the warming period and *speeded up* during the cooling period. What's the reason for this? A warmer climate leads to increased evaporation from oceans, and part of the evaporated water rains back as snow on the Antarctic and on Greenland, thereby effectively taking water out of the oceans. According to the article linked below, the real cause of rising sea levels appears to be the continued melting of the west antarctic ice sheet that has been going on ever since the end of the last ice age. Unless there's another ice age, we can expect sea levels to continue rising for the next 7000 years or so until the WAIS is gone. This melting has nothing to do with global warming, and there's really nothing we can do about it. The bottom line in all this is that the climate is a fiendishly complex thing, and the people who tout simple answers are more than likely incorrect.

Answer 3

You are probably in more danger of the poles shifting and the earth rotating on its axes so that what are now the poles will become part of the equator and vice versa. There is evidence this has occurred in the past. Don't worry about icebergs melting and raising the sea level. When ice melts the level of the water in which it is floating does not change, hence the calving of the ice floes from Antarctica are not a danger in that respect. And since, even though the ice around the Arctic shelf is melting, the interior ice is gettng thicker, there doesn't seem to be much to worry about there either. Your great, great grandchildren may be at some risk, but probably not due to global warming, because we will probably be in a global cooling cycle by then anyway.

Answer 4

Global warming and cooling are a cycle and contineous process in our earths system. 20000 yrs back we were passing through a cooling or ice age era and we had ice caped mountains even near tropics and equator.

We have lost a few civilisations to this cycle including Mayan and Eqyptian one and Indus valley people had to shift to Ganga valley belt. Sri lanka which has become an island now and Dwarka region which is submerged in sea were a part of main land India once.

So Global warming certainly will effect the coastal areas first especially low lying regions like Bangladesh and Calcutta. They will be lost to sea first and other low lying areas will follow suit.

As for time it will need is something very difficult to predict and atleast our modern science is not good enough to work on this but yes old science as we call it or the vedic science of Astronomy and astrology will certainly be able to help but I do not think any one has worked on this yet. Some people say it may take between 40 to 50 years to effect Bangladesh area.

Answer 5

Global warming will raise sea level.

The problem is more for island states like Lakshadweep and Maldives than for large land masses. There is no hope for these as the land mass will be obliterated. Even a few feet increase can substantially reduce available land area.

The climatic changes will be complex. The increasing temperature gradients can cause more severe cyclones with higher gale speeds. This can whip up higher waves. This combined with the higher sea level will cause more storm damage to low lying zones.

Tsunamis are tectonic in origin. There may not be more on account of warming. Though the damage done by them will be more when they happen.

You will have enough time to beat an orderly retreat.

Answer 6

There will be a definite and serious effect of melting polar ice caps.

According to NASA estimates, the situation by 2020 will be such that all coastal areas around the world will be submerged.

This will happen if the greenhouse gases continue at the current levels. IF a mass campaign is successful in reducing greenhouse emissions, we can buy more time...

What s needed is education and awareness. talk to people, your friends, your classmates, your neighbors and make them aware that WE DO face a serious problem.

Remember, if you are living sustainably and your neighbor isn't, you will still suffer the effects of global warming. Counter-measures work only if everyone of us contributes to it and understands it. Please spread awareness and follow tips and ways to live more sustainably.

there are lot of ways we can help. Go through this website, it gives a few pointers of what we as consumers can do

Answer 7

YES, global warming is raising the sea water level approximately by a centimeter per year. As per a calculation it may take about 40 years to melt all the glaciers and the water will ultimately reach to the sea resulting in rising of sea level.

Answer 8

It is and the pace of sea levels rising ranges from virtually over night to decades. There are a number of ways this may occur overnight. India has already lost islands in the delta, in fact entire island countries are slowly disappearing.

However if a slippery glacier slips into the ocean, and they will, or the side of a coast line slides and they will, there will be no escape.

Answer 9

Alaskan arctic was the first pollution sink, and the air and water both expanded, causeing widespread damage to eskimo (iniapiat in Canada). I do not know when India will get hit but it's not if, it's when. Currently both arctic ice cap and antarctica are melting at breakneck speed. The rise of the arctic ocean is just about to hit a high level of catastrophic proportion's due to it's expansion from heat within the ocean and land permafrost methane expulsion. study fast,act soon.

Answer 10

If you live in the coastal area in india, it will not take too long until the water in the pacific takes over the coast lines in India. I would say about 40 years from now.
