Do Jet Streams Vanish with Arctic Sea-Ice?

What happens to the jet streams when we lose all Arctic sea ice and snow cover? Do they vanish? Do they still exist as a weak remnant farther north? Does the 3 cell atmospheric circulation reduce to 2 cells or even 1 cell? It would be nice knowing these things, before they actually happen in a few short years
