Hmm: On Sept. 6, warmist John Vidal told us that the edge of the Arctic sea ice was at 82-84 degrees N; a few days later, when he reached the edge at 82 degrees N, he claimed this was "*far* further north than expected"

The plan is to steam to, and possibly then into, the furthest extent of the annual sea ice which right now is about 82-84 degrees north, about 500km from the north pole. Given good weather that's at least four days away in this much loved 37 year-old-tub. At least it's an ice breaker.

Strove shows us data sets showing how vulnerable large parts of the ice mass has become. Ten years ago, she says, a good 30-40% was older than a year, meaning it was thicker and more resilient. This year it's nearly all only one year old. Even more remarkably, she shows us the temperature anomaly charts – much of this vast region is presently 2-6C above normal temperatures for this time of year.

After setting out from northern Norway last week to witness this year's record sea melt in the Arctic, we reached the edge of the Arctic polar ice cap this morning. It's far further north than expected, at around 82 deg N
