Simple enough, Santa owns a private island at the North Pole. It's not on any map, as so many would try to go there if they knew where it was. It is also protected by a constant invisibility spell, to keep from being spied on by satellites.

Time to watch.

Next few days should be pretty exciting.

Ohmigosh. Look how far the pack ice is north of Alaska.

The polar bear cubs are absolutely screwed this year. No way they can swim that.

Where's my cub? He was with me up until about 10 miles ago............

Fast-melting Arctic = sign of bad global warming

https://www.washingtonpost.com/politics ... 1aab5e5cc7


"It’s not just sea ice on the decline. Glaciers in the Arctic are shrinking. And the massive Greenland ice sheet is slowly but steadily melting and that can add a big dose to sea level rise. Since 2002, it has lost 4,400 billion tons (4,000 billion metric tons) of ice.

Then there’s the Arctic carbon bomb. Carbon dioxide and methane — which traps even more heat — are stuck in the permafrost in places like Alaska and Siberia.

“Roast the Arctic and you create a mess everywhere on Earth,” said Princeton University climate scientist Michael Oppenheimer."

Pen Hadow sets sail for North Pole as Arctic ice melts

Pen Hadow sets sail for North Pole as Arctic ice melts.
http://www.bbc.com/news/av/world-us-can ... -ice-melts
British explorer Pen Hadow and his crew have set sail from Alaska, in an attempt to become the first people ever to sail to the North Pole.

With Arctic ice melting at an unprecedented rate, previously inaccessible waters are opening up, creating the potential for their planned 5,500 km (3,500 mile) journey for the first time in human history.

I have to doubt he will get anywhere near the pole this year considering the average temperature north of 80 deg. N latitude. The melt season is rapidly approaching it's end and the sun sets seven minutes a day sooner at the arctic circle each day and will set for the winter at the pole in just forty days.

The thickest sea ice in the Arctic Ocean is located close to the north of Greenland and the Canadian Archipelago. This ice is now breaking up, due to high temperatures and strong cyclonic winds that cause warm rain, high waves and strong sea currents.

Watch the thickest sea ice break up on the animation below. This is a 17 MB file, so it may take some time to fully load. Click here if you do not see the file appear below.

The animation below shows the thickest sea ice breaking up between July 14, 2017, and August 13, 2017.

great vid, mbs.

The heat anomalies in the general region are quite stunning. And further south they are helping to spark enormous and explosive fires, ash from which will surely fall on CAA and Arctic Sea ice, probably leading to faster melt while the sun is still up up there.

One of the consequences of sea ice melt is walrus end up living on shore in the thousands. And that puts them at risk of polar bears and stampedes:

This used to be a rare event; now it's becoming an annual event, and happening ever earlier.

Once in the atmosphere, weather patterns are causing the wildfire smoke to converge into a blanket so thick it's blotting out the sun across northern Canada. This smoke is working its way to the high Arctic, where it could speed up the melting of sea and land ice.

At this point, most of that melting effect will happen next year, since the sun is already getting low up there. I doubt all that soot will be expelled from the sea ice over the winter, the way salt can be.

The glaciers in the CAA will definitely darken, too. More bad news, and a further feedback.

Would not a soot deposit this late in the year get covered up by the coming winters snow fall? Only a snow fall drought would leave it exposed to affect next summers melt season.

Eventually, that snow will melt, revealing the dark layer below. At that point, things will melt much more rapidly. We'll see.
