Via Prometheus I read this article from the AFP that describes some new findings about land mass in the river delta that is Bandladesh. Apparently it is growing and has been for the last 32 years at about 20 km^2/year.
Roger points out, no doubt correctly, that the climate septics will make great hay with this, as supposedly another IPCC prediction turns sour.
But will they be correct?
Regardless of the extent of the Bangladeshi delta, obviously the only thing that will determine if it is submerged or not in future sea level rise scenarios will be its altitude. 640 square km of new land is great, but if it is all below one metre of sea level rise then it may not last til the end of the century. Approximately 50% of existing Bangladesh would be submerged as a direct result of 1 metre of sea level rise, more would be vulnerable to increased erosion. I dare say that most if not all of the new land being created from silt deposits is both very low altitude and very vulnerable to erosion and will join the unfortunate half destined to be continental shelf sooner or later.
So, while it will be an effective talking point for the “lawyer science” of the climate denial industry, I hardly think this makes Bangladesh any less vulnerable to sea level rise.
