Guyana sea level

Reading a recent BBC article on sea level rise I was reminded of an article in one of our main national newspapers (Stabroek News) . The first article is about recent research suggesting that the rate of sea level rise is more than some had predicted and is about 10mm per year:
The team from Germany and the US found that for the timescale relevant to human-induced climate change, the observed rate of sea level rise through the 20th Century held a strong correlation with the rate of warming.
When applied to the possible scenarios outlined by the Intergovernmental Panel on Climate Change (IPCC), the researchers found that in 2100 sea levels would be 0.5-1.4m above 1990 levels.
This agrees with local records which are referred to in the Stabroek News article:
According to the project document, an analysis of tide gauge records from 1951 to 1979 shows the trend in sea level rise for Guyana to be in excess of 10 mm/year, which implies a net change in sea level of 0.9 ft for the 28-year period examined. Assuming that the rate found remains constant then the net change in the sea level from 1951 - 2005 is some 1.8 feet. According to the studies quoted in the PID, sea level rise in the region of Guyana is 2 to 5 times faster than the global estimate.
The project referred to seek to address water control issues arising from climate change.
Given that most of our population lives near or below sea level these figures indicate how serious the situation is for us here! Short-term planning no longer suffices...

This is welcome. I've been so struck by the level of inattention in Guyana and the rest of the Caribbean to the implications of Global Warming, that I put up a website and blog to get something going. Please feel free to visit and let me know if you want to set up mutual links.
