The Effects Of Global Warming On Sea Levels Essay

One effect of global warming is the increase in sea levels. The increase in the levels are scarier than what the leading climate models predict. Unfortunately, these models do not account for the sheer velocity of the breakup of ice sheets and glaciers, NASA scientists confirmed. What 's more, the sea level rise is already occurring. The open question, the NASA scientists ponder, is just how fast the seas will rise in the future. The warming of the seas and the expansion of the waters make up one-third of rising sea levels around the world. "When heat goes under the ocean, it expands just like mercury in a thermometer; the remaining two-thirds of sea level rise is occurring as a result of glacial and polar melt from ice sheets in Greenland and Antarctica, and mountain glaciers," Steve Nerem, the lead scientist for NASA 's Sea Level Change Team said in the press briefing. Global sea level rise of about 1.9 millimeters (0.07 inches), viewed from NASA satellites in space prove that ice sheets are melting. "Ice sheets are contributing to sea level rise sooner, and more than anticipated; That 's because people have never seen the collapse of a huge ice sheet and therefore don 't have good models of the effects," said Eric Rignot, a glaciologist at the University of California, Irvine. The Intergovernmental Panel on Climate Change, produce climate change models that predict that sea levels could rise as much as 21 feet (6.4 meters) in the next century. "If all the land ice…
