Dear all,
For last few weeks, I see several people are posting about 25 m sea level rise. Scaring everybody like chicklets. This is an issue which is not very clear yet and general public have nothing much to do about it except voicing to stop the big polluters to reduce and ultimately stop polluting. It is not always very easy. For example, can you ask all rice producers to stop wet and under water ploughing that contributes a significant amount of greenhouse gas, can you ask all coal burning plants to stop burning coals, can you ask all motorists to stop driving? You can't. So, it is necessary to learn the facts on this issue, try sincerely to make adjustments, approach towards amicable solution by the world folks together. Individual country can't do anything about it. Excess of everything is bad. Remaining indifferent about these environmental problems would be very wrong, I would equate it with some kind of crime, but some of the environmental activists are scarring and terrifying people giving wrong information to public. Like, the posting below is citing 25 meter sea level rise, giving reference to Professor James Hansen, the director of NASA's Goddard Institute for Space Studies. The following link is for that published article. Please read it. You will not find 25 meter sea level rise anywhere in this article.

Professor James Hansen mentioned, ' Rahmstorf (2007) has noted that if one uses the observed sea level rise of the past century to calibrate a linear projection of future sea level, BAU warming will lead to a sea level rise of the order of one meter in the present century.' However, he thinks if the West Antarctic ice sheet is largely depleted then a non-linear action may start that may yield a sea level rise of the order of 5 m this century. This has not been proven, and just a mere guess yet. The opposite may also happen that the other scientists think that the melting of huge amount of ice may cool off the existing warm sea current that keeps north-western Europe warm. That will definitely affect the environment. So, many variables are not yet known on this issue and where we general public can't do too much about other than learning and voicing, we should not be scarred and alarmed. Lets try to remain awake and learn as much as we can on these types of crucial issues.
I could not stop myself telling one thing is that about a decade ago when ethanol issue started surfacing, I always said that the ethanol will do lot more harm than good for the humanity. Business tycoons will step into it and convert a lot of human food to the cars. It will accelerate hunger worldwide because the export will stop and the less fortunate countries who can not produce their food will die by hunger. It is happening now. Company like ADM grabbed entire American Prairies, which is by the way, world's food basket. Most all food grains are going to local ethanol plants rather than being exported outside. Food value rose skyrocketed all over the world, including USA, who used to feed the entire world. Now ethanol's contribution !!!!! Ethanol pollutes is polluting the environment in the process if manufacturing 5 times more that what it would save the environment while burning in the car. It also takes more than 3 times cost to the same amount of gasoline for manufacturing. So, what we are gaining from ethanol?
When we make an issue scary, political opportunists line up with profiteer business tycoons, and eye washes public by this and that and scary public hails it but in course of time truth comes out when repairing the damage becomes too late.
Please see the article which is ''Church_White_Study on Global sea-level rise'' in the following link:
http://www.pol.ac.uk/psmsl/author_archive/church_white/GRL_Church_White_2006_024826.pdf
This study indicates that in this century only 1/3 meter of sea level will rise.
We do not know yet what will happen. Lets remain informed, educated, active but calm. There is no reason for scarring. There is another phenomenon existing for the lower Bangladesh which is the river born silts from Himalayas, India, Nepal and Upper Bangladesh. This silt sedimentation at the earth surface in Bangladesh is lifting the bed height higher day by day and I believe it will not be less that the rate of sea level rise. Let some good scientists study that phenomenon. There is no good publication on it yet. Lets wait and see what happens.

Subject: [bdresearchers] Bangladesh is set to disappear under the waves by the end of the century
Dear All:
You may find it necessary to read the following article though it is a long one. It elaborates how Bangladesh may disappear under water by the end of this century.
I did not know the river water of Munshigonj had turned salty and may be the process will be continued. According to Professor James Hansen, the director of NASA's Goddard Institute for Space Studies, we are facing a 25-meter rise in sea levels this century – which would drown Bangladesh entirely. I am quoting the last line from the article 'The headstone would read, Bangladesh, 1971-2071: born in blood, died in water'.
