The sea is falling in Juneau, Alaska, because land freed from melted glaciers is rising about 0.6 inches a year
The sea is falling relative to the shoreline in Juneau, Alaska, even as global sea levels rise. Land once pressed down by massive glaciers is rebounding at approximately 15 mm (0.6 inches) per year, lifting the coast faster than the ocean is rising. NOAA’s tide-gauge measurements show a relative sea-level decline of about 13.5 mm (0.53 inches) per year, revealing how centuries of glacier retreat continue to reshape Southeast Alaska’s coastline.
