Obviously warmer water is bound to melt ice faster. Above AMO index and Antarctic ice area is shown. Notice the simultaneous trend shift around 2005-6.
Above: Dark blue is Arctic sea ice area. Light blue shows AMO index, that is, how much warm water reaches the
Problems using summer ice as indicator of Ice area: Areas in the
Winter ice area on the other hand is a more stable indicator of Arctic Ice area..

Therefore, the Arctic Ice area does not seem to be near a tipping point, but rather the Arctic ice area appears controlled at least partly by the AMO. (Other factors, see ”
AMO peaked last time around 1940. AMO in recent years:
