Just cause it turned up the other day, here's an article on the threat facing Bangladesh in particular that Judith Curry posted on her website - Curry being a favorite of the AGW denialist crowd, I'm assuming even the Schmelzers of this world will find it acceptable reading:

Different from you, I do not value sources based on the question if I like the results or not. The relevant question is if they follow scientific methodology. The link is a blog, thus, not really a scientific source, but so what, this is what one has to expect from iceaura - never give the scientific source itself. In this case, the reference would be
Pethick, J., Orford, J.D. (2013). Rapid rise in effective sea-level in southwest Bangladesh: Its causes and contemporary rates. Global and Planetary Change 111, 237-245
So I will use this source, instead of that irrelevant blogger.
The article itself is not uninteresting because it describes also reasons for local sea level rise which are not related to global warming at all. In particular, the change of the geometry caused by various embankment building also changes the tidal range. It is one thing if what is pressed into the river from the sea by the tide meets a wide unprotected area or an embankment. So, if you build embankment, you have to expect that (because of the changed geometry) the tidal range increases.
The rate of increase in ESLR is shown to be due to a combination of deltaic subsidence, including sediment compaction, and eustatic sea level rise, but principally as a result of increased tidal range in estuary channels recently constricted by embankments
...
Khulna is located within the polder area of the SIZ where channels have been constricted by embankments (Islam, 2006) and deepened by dredging (IWM, 2004), so that, in addition to the natural response to sea level rise, tidal range will be amplified as a result of these anthropogenic activities. At Khulna the total contribution of tidal range to observed ESLR is c. 83%.
Emphasis mine. Fine. With these numbers, another question appears. Is it appropriate to use well-known and predictable side effects of useful human activity (constriction of the river by embankments), and add these effects to the sea level rise? And then forget about the origin? The problem is that what is caused by that human construction will be, plausibly, a one-time effect: The tidal range has increased and will remain higher, but without further embankment building there will be also no further tidal range rise, not? That means, you cannot simply add this "rise" to the expected rise for all the future years.
Whatever, let's ignore this question and look at the numbers: "by the year 2100 could range between 1.74 m and 3.24 m. This increases to between 2.01 m and 3.51 m at Khulna, in the densely populated area of the Sundarban Impact Zone." So, indeed, no problem for my argumentation, given that I have used 3-4 m per century.
That involves an assumption diligently and thoroughly promulgated by US corporate rightwing marketing professionals, faithfully repeated by essentially all AGW denialists in every media arena; and it's a political assumption: that scientific research into AGW has been corrupted by leftwing or liberal ideology and influence, politics, to the point that its reports, findings, evidence, even its raw data, have been biased toward assertions of greater threat rather than lesser, more serious harm rather than less, more bad consequences and fewer good ones.
Except that I do not question the results made by the researchers. Instead, I look at them, then I quote them to use these results in my argumentation. Left-wing, right-wing, whatever-wing, if it is an appropriate scientific article, I don't care about this. But for iceaura I'm nonetheless an AGW denialist. This is simply an axiom, to be repeated as often as suggested by Goebbels.
That assumption of fact - that the consensus or mainstream science is reporting an overestimation of AGW's rate, size, effects, bad consequences, etc (for any reason) - conflicts with the measured trends and comparisons between the consensus older predictions and incoming data. AGW is hitting harder and faster, in more bad ways and fewer good ways, than was authoritatively predicted as likely fifty, forty, thirty, twenty, even ten years ago.
The high side extremists among the AGW researchers have for fifty years been proving more accurate, in general, than the scientific consensus and official advisors
Ok, this open support for the extremist positions clarifies that my classification of iceaura as an alarmist is correct.
Of course, the data presented in iceaura's link, if one looks at them in the scientific paper itself, suggest nothing of this type, but attribute 83% of the observed (indeed quite large) water level rise to a side effect of human activity unrelated to global warming.
That wasn't a topographical map,
Indeed, it was a very degenerated case of a topographical map. A usual topographical map presents many different contour lines, corresponding to different elevations, here there was only a single contour line, which marked the contour of the waterside after a particular sea level rise. So, all the irrelevant contour lines have been removed, only the contour line of interest was presented.
The map showed what would be AGW disaster if the map were relevant - if it showed what could happen at the rate AGW is kicking in.
It showed the worst imaginable final result. All of Antarctica and Greenland ice melted. So, a safe upper bound for the horrors.
Oddly, you seemed to think it supported your bs, apparently not because you understood it was an irrelevance used for deflection, but because the little dark band of flooded continent didn't look significant to you.
You simply don't know any better.
LOL. Of course, this worst case final result is significant. That's why I have considered what could be done to prevent most of the harm. But there is time to adapt, a few thousands years. With that time scale, it is far from catastrophic.
Not equivalent ones.
They have done amazing things, but diking Bangladesh against AGW's predicted effects would take another level of terraforming altogether - as a glance at a topographic map (look it up in a dictionary) will show you, if you haven't the time to read the Curry link I posted above.
And nobody has the time anyway.
The blog link is, indeed, irrelevant, but in the paper it referred to there were interesting facts about what Bangladesh was able to do in the last century: "Between 1961 and 1971 a total of 10,000 $km^2$ were reclaimed, with 92 polders created within 4022 km of embankment (Islam, 2006)." So far about how impossible it is for Bangladesh to manage embankment over thousands of km. And the source they referred to (Islam, M.R., 2006. Managing Diverse Land Uses in Coastal Bangladesh: Environment and Livelihoods in Tropical Coastal Zones. 237–248.) gives also a picture of the polders finished up to 1980:
And especially for those who may think that this is something very different from the Dutch polders, the explanation of the meaning:
The Dutch term ‘polder’ was used to designate areas that are surrounded by dykes or embankments, separating them hydrologically from the main river system and offering protection against tidal floods, salinity intrusion and sedimentation. The embankments include regulators and other structures to control water intake and drainage of the empoldered area.
So, if the sea level rises 3-4 m during the next century, those poor Bengali people have to increase the size of these dikes and embankments (which they have build in 20 years of the last century) by 3-4 m during the whole next century. I would naively expect that this does not need more time than the same 20 years. So they will also have 60 more years up to 2100 to build similar embankments upstream to protect the areas upstream.
You can read the argument in the article I suggested for you, above - the one you claim to have read.
Once you prefer not to quote, there is only a probability of 0.1% that there is indeed something written there which supports your claim. Whenever you refer to something scientific, even if only implicitly via some blog, and the scientific source can be identified and accessed, one will certainly find nice things there which are in conflict with your claims.
