80m Sea Rise maps - Africa, Middle East, Pakistan, India, Bangladesh


Using Google Maps and the Sea Level Rise applet, the following maps show 80 metres of sea level rise.


Areas shaded red are those areas inundated.


Africa

South-East Mediterranean - Egypt

Iraq - Pakistan

Pakistan (Detail)

India-Bangladesh


I strongly recommend you check with your local maps to review the location of the 80 metre contour in your area of interest

  1. ROFLMAO! I was looking up what sea level rise could be expected from a 2C or 3C temperature increase over 100 years, and I came across your absurd maps. Do you SERIOUSLY think that sea levels are going to rise by 100 meters within a time frame of interest of, say, 100 years? That entails the melting of the entire Antarctic and Greenland ice caps - a process which will take THOUSANDS to MILLIONS of years at bare minimum (assuming absurd levels of temperature change). Even your sidebar testifies to this absurdity when you project sea levels out to 2500 AD to 2700 AD. Seriously, we can predict the future 500 years from now, the level of technology humans will have achieved, and we have complete knowledge of all the processes that affect climate?

    If this site wasn't a complete joke, you could perhaps do maps of, say, what the shoreline might look like with a 2 meter rise in sea level (projections indicate around 80cm rise by 2100). Even that map will completely miss the point that people aren't going to be displaced by sea level rise associated with global warming: Hundreds of Millions in China have already been "displaced" from the countryside into cities; Tens of Millions in Europe and America are "displaced" annually because almost nobody will live at the same location they were born by the time they are at university or working. Mass displacement assumes people are static over decades - a complete mis-assessment of reality.

    You're better off quantifying other potential effects of global warming. The sea level stuff is academically "interesting", but quite a waste of time practically speaking.

  2. Thanks for your interest, you raise some good points.

    The melting of the ice sheets is underway and it will only stop when the CO2 levels return to pre-industrial levels.

    I postulate a 1000 to 2000 year melt out, but it could be slower, or faster, depending on whether we continue to take carbon out of the ground and put it into the air. Its our choice.

    I started by looking at the effect of sea level rises of a metre or so, and what we should do about that. But when that view is blended with peak oil we find that we only have another 5 to 10 years from today to use oil to rebuild our global coastal infrastructure.

    So we can only do that once, before our primary energy source is effectively gone. If we must do it once, then we have to build for the probably longer term future. That is why I recognise total melt of 80 metres sea level rise, and a prudent step above that for key infrastructure.

    Hence - The 100 metre line.

  3. As always an excellent posting.The
    way you write is awesome.Thanks. Adding more information will be more useful.
