Rising Water Effects for Buenos Aires or Rio de Janeiro
Back in April and May we saw some examples of using Google Earth's time animation feature combined with 3D data to illustrate the approximate effects of rising sea levels on various locations. First we had some examples of the effect on New York City and also a fun example of what the Grand Canyon would look like if you filled it with water. Later, Leszek Pawlowicz - who authors the FreeGeographyTools blog - showed how to use some GIS tools to do a more accurate visualization of rising water on NYC.
Now, Gerardo Paz - who not only appears many times in GEB for his innovative visualizations, but also writes the spanish version of Google Earth Blog - has now produced some time animations showing the rising water effects on Buenos Aires, Argentina 
and another one for Rio de Janeiro, Brazil . Once you load one, click on the right-arrow "Play" button next to the time slider in the upper center of GE to start the animation. As Gerardo notes in his post, the visualization relies on the 90 meter resolution of terrain from NASA which is used in Google Earth. The simulation is only approximate, but clearly a larger rise in water could have a devastating effect on these cities.

That certainly is creating a bit of waves in Buenos Aires
