NASA is facing a climate change countdown

Like so much of Florida, the Space Coast — a 72-mile stretch along the Atlantic — is feeling the threat of climate change. Some of the erosion is caused by the churning energy of ocean currents along the coastline. Hurricane Sandy, whose power was almost certainly strengthened by climate change, took a big bite in 2012, flattening an already damaged dune line that provided protection from the Atlantic’s battering.

A rising sea level will bring even greater risk over time — and perhaps sooner than most researchers expected. According to a study published last week, warming pressure on the Antarctic ice sheet could help push sea levels higher by as much as five or six feet by the end of this century.
