A friend who works at the Jet Propulsion Lab just sent me this link (am getting ready to use it with my ESL students who come from various parts of the world). It shows how each melting glacier will affect each city around the globe. The interesting fact - and it's quite counter-intuitive - is that proximity does not seem to be a factor because, if I understand well, the loss of gravity associated with a melted glacier makes the water recede near the immediate area (the water re-appears on the other side of the continent or of the world). Anyway, it's fun to chose a city, drag the mouse to rotate the globe and see which glacier will have an impact. The melting of the glaciers of Greenland, for example, has an impact on most cities except the ones nearby.
