From the BBC:
As many as 1,500 of Indonesia's islands could be under water by 2050 because of rising sea levels, it's been reported.

In the capital city, Jakarta, the main international Soekarno-Hatta Airport could be below sea level as soon as 2030, with outlying districts turned into lakes, says Singapore's Straits Times, quoting a report from Maplecroft's Climate Change Vulnerability Index.

"This archipelago's biggest threat is rising sea levels, where 42 million people living 3km from the coast are vulnerable," Ancha Srinivasan of the Asian Development Bank says.

Twenty-four islands have already disappeared off the coast of Aceh, North Sumatra, Papua and Riau, according to official research, and experts are worried this trend could accelerate. Indonesia comprises around 17,500 islands, of which approximately 6,000 are permanently inhabited.
Would it surprise you to find that the BBC have not been telling you the whole story? No, thought not.

The major factor in "sea level rise" in Indonesia has nothing to do with global warming, melting glaciers or wicked Republicans. It is that the land is sinking, as this study by Yanagi & Akaki in 1994 showed.

And they include these maps, showing the rate of sinking, and where the plates meet. Around Jakarta, the land is reckoned to be sinking at 8.7mm a year, about 34 inches a century. In other parts it is worse still.

But the BBC's omissions don't stop there. According to the Jakarta Globe:

So, when you add the effects of sinking and subsidence together, an odd millimetre or so a year is neither here nor there.

And, for the record, what is sea level doing, in other parts of the Pacific, away from the dramatic changes around Indonesia? Freemantle, in Western Australia, has a long running tidal gauge, and according to Church & White, the land there is rising by a relatively small 0.25mm pa.

Sea levels have been slowly and steadily rising by 1.54mm a year since before 1900. Furthermore, the rate of increase has actually been DECLINING in recent decades.

But don't expect the BBC to tell you any of this. It suits their agenda to let you think it is all due to global warming.
