By how much has the sea water level risen in the vicinity of The Maldives?

Since 1993 when satellite monitoring of sea level began (1), the sea rose around the Maldives (2) about 10 cm (3). For sea level changes before 1993, one needs to check the tide gauges. However, good tide gauge data for those earlier years is lacking in that part of the world (4). Using the tide gauge at Kerala, India, sea level rose at a rate of about 2.5 cm/decade from 1975 to 2008, indicating that there was very little sea level rise between 1975 and 1993 in that area. In fact, there has not been much sea level rise in the Maldives between 1950 and 2003 as evidenced by photographs of the marker tree (5).

Edit: @Asker:

My link (4) does indeed show a number of gauges in the Indian Ocean. They appear and disappear depending on the start and stop dates selected. Note that I specified the period 1975 - 2009. Notice the slide bar below the map where you can use your mouse to adjust the start - stop dates. Plug in my specified dates, and the referenced gauge data will appear. Sorry about the 200'8' typo. Putting '2008' in will result in no data.

In the north west of England, the Cumbrian coast is growing grass on what was sand , the explanation was the crust was pushed into the magma by a mile thick layer of ice & it's still rising out of it.

Judging by the number of resorts they have built, even they don't believe in the rising sea level threat.

Trevor: Give up. That Commodore 64 you presently use, was a great computer in its time but we have passed on since then.

As far as your link, Maxx, it works fine and actually disproves Gringo's bluster.

Notice the lowest ocean level was 1998. The hottest year, according to woodfortrees' charts. If I were a Maldivian I would pray for Global Warming and Climate Change and a host of other things the greenies find repugnant.

Baccy Baby: Just because a person doesn't question something doesn't make that true. You should be a scientist enough to know that. What science do you adhere to anyway?

Caliserv: GREAT article!

Trevor, this is the study Maxx is trying to link to:

Simon Donor, Eos, Transactions, April 2012

http://onlinelibrary.wiley.com/doi/10.10...

Additionally, Donor explains his research intentions and interests. He does not specialize in sea level rise, he does not question that sea level is rising and he does not question AGW. He does dislike seeing natural events used evidence of global warming without support because it gives skeptics opportunities to make false claims. Donor is an advocate of media being as careful as scientists are when talking about climate change.

There is no significant rise in sea level around the Maldives.

Flossie,

I don’t have immediate access to figures specifically for 1975 but what I can tell you is that when studies were conducted in the 1950’s the rise in sea-levels was found to be between 0.8mm and 1.6mm per year. Current satellite observations show the sea is now rising by 9mm per year, a figure verified by tidal gauges around the Maldives.

This means that sea-levels are presently rising at nearly three times the global average (3.2mm per year).

Today there are 90 Maldivian islands, out of a total of about 1200, that are subject to inundation from the seas. The authorities have embarked on a programme of land reclamation to get back land lost to the sea.

If we assume a linear trend in the rate by which sea levels have risen then in ~1955 it was 1.2mm per year, in 2013 it is 9.0mm a year. In 59 years there has been a 7.8mm increase in the annual rate of SSL, this means that rate of sea-level rise is increasing by 0.132mm per year.

In 1975 the sea-levels would have been rising by just under 4mm per year and therefore the total rise from 1975 to 2013 looks likely to have been around 250mm.

This would only apply if there has been a linear rise in SSL which is unlikely to have been the case as most warming has occurred since 1980. It’s therefore likely that until this time there was little change in the annual sea-level rise, namely that they were rising by about 1.2mm a year.

From 1.2mm per year in 1980 to 9.0mm by 2013 means that the actual sea-level rise is more likely to have been around 150mm rather than 250mm.

If the present 9mm per year rise is maintained into the future, and indications are that it will increase rather than remain constant, then by 2100 some three quarters of the land will be underwater.

For more info see if you can locate “Estimates of the regional distribution of sea level rise over the 1950–2000 period” which was published in the Journal of Climate in July 2004, pages 2609 to 2625, volume 17, issue 13.

I can’t get your links to work (poss a temporary glitch), is this the image you’re linking to?

Thanks but still can’t open it, seems to be the graphics that’s causing the problem. Google’s cache doesn’t pull through the graphics but I can get a text only version:

It doesn't matter how much sea level has risen, bu how much it can rise. On August 5, 1945, the people of Hiroshima were doing fine.

Would you prefer it if the Maldives were already under water? So what if you are mad? I would rather you be mad than risk millions of lives.

By how much has the sea water level risen in the vicinity of The Maldives in the last 40 years or so?

First, and last, time I was there was around 1975, would be interested how much land has been lost by now.

I flew into RAF Gan, is it still an airport or below water?
