“Bengal Island succumbs to global warming nonsense – AP gets nutty over the loss of a sandbar“. A newspaper suggests that a tiny island in the Bay of Bengal has sunk below sea-level due to “global warming”. This sets Anthony Watts and Steven Goddard off on a rant that sea-level change can be due to sea-level rise or surface subsidence.
This is true! There are a number of local factors that affect “sea-level” in either direction. Sediment compaction. Erosion. Sediment deposition. Changes in ocean circulation patterns. Storm activity. Glacial rebound. Earthquakes. Plate tectonics. What does this have to do with global sea-level changes? Nothing.
Next up is the discovery of an ancient city 36 metres below sea-level off India’s western coast. Anthony says “How many Hummers were they driving 9,000 years ago? Chalk up another clueless AGW claim.” I guess Anthony and Steven haven’t heard of earthquakes.
It’s the denialists who are trying to build the straw-man argument that global warming is the only recognized source of sea-level change. Real scientists know better.
Before posting nonsense like this, you might want to check your facts. Sea level has risen 40 meters in the last 9,000 years.
[Good point! I knew that, but lost track of it while trying to catchup with Anthony’s heroic output… The key factor about the graph that you link to is that the natural sea-level rise basically ended about 7,000 years ago and we should be approaching a drop. Instead, it’s begun to rise again. Why? – Ben]
You write like a thoughtless zealot. [Striking a nerve, am I? – Ben]
Once again, you need to check your facts. Sea level rise has been steady for 100 years.

Bad science always irritates my nerves. [And your reaction to WUWT is? – Ben]
James Annan had a post about this – basically, it’s sandbars being sandbars.
