People often say that the ACC effectively seals off heat transport, but I'm not
sure its true
What are the state of the art wild gueses wrt the stability of the
circumpolar current? What drives it, and could it stop? My very
poorly educated impression is that this current has been chugging away
for 10's of millions of years, basically ever since S.Am. seperated
from the antarctic penninsula.
