A group of Bay Area legislators and scientists met at College of San Mateo Monday to discuss the issue of rising sea levels.
"The glaciers and the ice sheets on Greenland and Antartica and going to melt enough to cause the sea levels to rise eventually from three feet then six feet and nine feet so we have to adapt to higher sea levels," sea level adapation expert John England said.
The biggest concern is the potential for flooding at San Francisco International Airport, which could happen by 2100.
Some of the steps discussed include extending the sea walls, but that could lead to shortended runways, which would force planes to land at much steeper angles.
Scientists can't peg exactly how quickly sea levels will rise.
