Has veteran climate scientist James Hansen foretold ‘loss of all coastal cities’ in latest study?

Former NASA climate director James Hansen and a team of scientists may have uncovered a mechanism in the Earth’s climate system not previously understood that could point to a much more rapid rise in sea levels.

When the Earth’s ice sheets melt, they place a freshwater lens over neighboring oceans. This lens, argues Hansen, causes the ocean to retain extra heat, which then goes to melting the underside of large ice sheets that fringe the ocean, causing them to add more freshwater to the lens (positive feedback loop).
