World's Coastlines to Bear the Brunt
In 2007, scientists were unclear exactly how the Greenland ice sheet would react to a rapidly warming world, a factor that many critics used to question the sea level projections in the IPCC's fourth assessment. This time around, scientists say they have a lot more figured out. As a result, they have increased their sea level rise projections.
The IPCC now says that the world's oceans could rise anywhere from 10 inches to 2.7 feet by the end of the 21st century, depending on the increase in greenhouse gas emissions. The rate at which this rise will occur is unclear, but the scientists estimate that about 70 percent of the world's coastlines will be affected.
