Sea-level rise is seen a key consequence of global warming, and much of the
concern has focused on the big ice sheets that contain the vast majority of the
Researchers writing in the online journal Science Express estimate melting
glaciers, which are located all over the globe including in the tropics, could
add between 4 and 10 inches (0.1 to 0.25 metres) to world sea level this
While this may not sound like much, consider that some 100 million people live
