Re: [geo] Could we slow the flow in the Drake passage to reduce the circumpolar current and winds around Anctartica? And what would the effect be?

Hi Brian, My first thought was that you must be mad to even consider such an idea. But actually there is an acute problem with warm ocean currents melting away at the terminations of Antarctic glaciers and causing accelerated ice mass loss "beyond a tipping point" for some glaciers. If we could m

Hi Brian, I believe the ice is thickening over most of Antarctica, as ozone (a powerful greenhouse gas) is reduced in the "ozone hole", cooling the region and creating a strong vortex. Sea ice is growing. The opposite is happening in the Arctic, with rapid warming, sea ice retreating, and vortex

[geo] Could we slow the flow in the Drake passage to reduce the circumpolar current and winds around Anctartica? And what would the effect be?

The drake passage is around 800 km wide and if the current in the southern half of the passage was slowed (even slightly) the Antarctic continent could be released from its splendid isolation. If a series of anc
