Proposed Solution: To prevent future melt, a 100-meter-high wall with sloping sides of 15° to 45
could be built across the 5-kilometer fjord sill shown in diagram above. This could be done by
dredging around 0.1 cubic kilometers of gravel and sand from the ocean bottom further out (on
Greenland's continental shelf) and adding it to the existing fjord sill to raise its height. This artificial
embankment, or berm, would then be covered in concrete to stop it from being eroded.
Feasibility: The scale of the berm would be comparable with other large civil-engineering projects,
such as:
• The Suez Canal excavated ten times more material - 1 cubic kilometer
Hong Kong's airport required ornu
