Unprecedented Collapse of the Arctic Beaufort Gyre

Unprecedented Collapse of the Arctic Beaufort Gyre // Published on Dec 13, 2017

As I walk through the seemingly endless hallways filled with poster displays of scientific observations and analysis on geophysical Earth topics (climatology, oceanography, natural hazards, hydrology, soils, rocks, etc.), I discuss highlights on the Arctic and Antarctic sea-ice talks that I attended all morning.

     

Most significantly, the Arctic’s Beaufort Gyre collapsed. This unprecedented event in late 2016/early 2017 occurred with rapidly declining sea-ice, letting ever increasing numbers of stronger storms from the Atlantic to enter the Arctic, bringing moisture and more warming. A vicious cycle of cascading feedbacks

And what is a big climate science conference, without Baba Brinkman?

Whoaaa (editor, dk)!

    Thank heaven for Canadian friends in high places and others trying to get US back for Science and hopefully actually giving exceptional effort toward stopping Extinction Absolute Nature of $ Trump, Putin-Russia Oil State Render of United States to bits as takings at End Cambrian E=02 Strong for Sky and Carbonate Balance between land runoff of carbon build up and deposition to Abyss of the Sea for sublimation into Mantel upper levels.
    Thank Goodness for Internet Communications and Industrial Capacity to have a chance to work symbiotic with Earth Biosphere to draw down the catastrophic dump of pecuniary interest Bank $. The Shoals of Time Forward and I bet God Standing thought wouldn’t even lift a finger to stop it…
    Erosion Rap Song Resonates in the halls of New Order for Life Sea at Standing and not mineral rights over the Lane where energy can go to machining centers and just in time scheduling cargo so work to out accelerate the build up and draw down of atmospheric loading can see showdown. Peace, and Thanks for all you do…

    I’m confused about the Beaufort Gyre – the reading I’ve done suggests that it’s supposed to stop/reverse every few years, but recently it hasn’t been doing that, and instead has just been accelerating in the clockwise direction. At some point when you get a chance, could you explain this whole topic a bit more? How this event is different from a “normal” reversal? Is it just that it’s been much longer than normal since it reversed – creating a salinity anomaly like was seen in the 1970s, or is something completely different happening? Thanks as always for your wonderful videos. You have a real gift for explaining these sorts of complicated topics to folks like me who don’t have a scientific background.

    Is the Beaufort Gyre reversing? June 2018 modeling suggests a low formation, but cant tell if its enough to kick out the strong high pressure in Arctic. Our trip around Hatteras last week, the north adverse currents very very strong, over 2 knots. Unusual as the Gulf Stream seems to be pushed more easterly due to it. West wall especially.
