DESCRIPTION

An updated version of the Dam Greenland project presentation. This project examines the idea of damming parts of Greenland to create a giant reservoir, preventing the melted glaciers’ water from entering the ocean, and thus reducing the effect of rising sea levels and changes in salinity levels.

*3 mm per year

*Many major cities will

disappear under the sea

soon

*Goal: 18 years

*18 years = 5.4 cm

In a few decades, Shanghai, New York, Los

Angeles, and Florida could all look like this picture of
