"Raise all that one foot and we might start seeing the groundwater table cropping out above the land surface, creating wetlands."

Sea-level may rise two to six feet by the end of the century, according to Fletcher.

"We have time, if we get started soon, to adapt to sea-level rise and the negative impacts of sea-level rise."

Fletcher emphasized that there are still a lot of other variables and unknowns and that scientists don't fully understand sea-level rise just yet.
