Northern European Enclosure Dam

The Northern European Enclosure Dam (NEED) is a proposed solution to the problem of rising ocean levels in Northern Europe. It would be a megaproject, involving the construction of two massive dams in the English Channel and the North Sea; the former between France and England, and the latter between Scotland and Norway.[1] The concept was conceived by the oceanographers Sjoerd Groeskamp and Joakim Kjellsson.[2][3]

As of 2020, the scheme remains a thought experiment intended to portray engineered solutions to the effects of climate change as too "extreme" to be pursued.[4] The scheme's authors describe it as "more of a warning than a solution".[2]

Groeskamp estimates that the NEED will cost 250 to 500 billion euros and will take 50 to 100 years to complete.[5] Groeskamp, an oceanographer, has not revealed how he determined the cost projection or construction timetable.
