So, this was released today. My third stamp with Canada Post. Qarlinngua (The pants). And technically my second stamp with a family member in it, as the tiny figure in it is my son Travis. Now for one with Hilary in it.

I’ve very proud of all of these, beyond the cache. They are about my home, and family. And also my family has a long history with the Post Office, 101 years. My grandfather, father, and brother were all postmasters in Roblin.

Tomorrow is the last day of Sun in town. (Technically another week but because of the topography we last see it Nov 5). Sun down all during this cabin trip.

Night time, below -37C. This is my home.

Happy International Inuit Day.

I saw a post today that the Arctic is best experienced from the comfort of your own home. Seriously this is one of the most magical places on earth and it’s by far best experienced full on, laying on the tundra, or standing at the floe edge, or having tea in a tent with a friend.

Some have asked where the cabin is, in relation to the photos of town I’ve posted. And while part of the route would be in those pano shots the cabin is really in the other direction. So here are some google earth screenshots that will show you the route from my house to the cabin. Coffee at the cabin won’t be on until next summer, but now you know how to get there.

Another screenshot of Google earth. Same route drawn on the image as the previous one, but zoomed way out. Arctic Bay and Nanisivik are labeled on the satellite map.

This is how we do it. A thread. To get the lengths of roofing metal over to the cabin on the ice we tied to qamutiiq together. Note. This much metal is heavy.

Another view of the qamutiiq lashed together with long metal roofing on top.

In der Klimawissenschaft ist ein Kipppunkt definiert als "eine kritische Schwelle, jenseits derer sich ein System neu organisiert, oft abrupt und/oder irreversibel" (Lenton et al., 2008). Hier sind 10 , die für uns zunehmend an Bedeutung gewonnen haben.

"Einige der im -Bericht erörterten abrupten Klimaänderungen und Kipppunkte könnten schwerwiegende lokale Klimareaktionen nach sich ziehen, wie extreme Temperaturen, Dürren, Waldbrände, Verlust der Eisschilde und Zusammenbruch der thermohalinen Zirkulation.

Es gibt Hinweise auf abrupte Veränderungen in der Erdgeschichte, und einige dieser Ereignisse wurden als Kipppunkte interpretiert (Dakos et al., 2008). Einige davon sind mit bedeutenden Veränderungen des globalen Klimas verbunden, wie z. B. die Interglaziale im Quartär (vor 2,5 Millionen Jahren) und die rasche Erwärmung während des thermischen Maximums im Paläozän und Eozän (vor etwa 55,5 Millionen Jahren; Bowen et al., 2015; Hollis et al., 2019).

Solche Ereignisse veränderten das planetare Klima für zehn- bis hunderttausende von Jahren, aber mit einer Geschwindigkeit, die tatsächlich viel langsamer ist als der projizierte anthropogene Klimawandel in diesem Jahrhundert, selbst wenn es keine Kipppunkte gibt" (IPCC, 2021).

Animated image. In the center, the picture of the Earth with the words "10 tipping points in the climate system" on it. Around, ten circles show the tipping points. They are - Ice sheet melting - Arctic Sea ice declina - Permafrost thaw - Coral reef death - Monsoon changes - Antarctic Sea ice loss - Switch to a permanent El Nino state - Interruption of Atlantic thermohaline circulating - Amazon forest dieback - Forest fires and pests in Boreal coniferous forests

It’s likely the last weekend working on the cabin until spring.

This morning’s sunrise. 360 degrees of colour.

One of the hallmarks of light here at certain times of of the year is the entire horizon is rimed with pink. Three days until the Sun returns.

So, when I said last week was the last trip to the cabin this season, I lied.

Hello all,

After a few months of testing the waters here I will do a thumbnail intro.

I'm a former stage technician who went and got a masters in with a focus on the regarding martime use, search and rescue, policy, and regional relations like the . Since then I'm a geography at my local community college and would love to do something else.

I also happen to love getting outdoors and exploring the world on foot and by

Cheers.

Tiriaq. A throwback to summer. An Ermine pauses. One of the challenges of photographing these little guys is that they hardly ever seem to stop moving.

I've designed a new graphic showing the daily ranking for sea-ice extent in nearly every region. This graphic will be updated several times per week at: https://zacklabe.com/arctic-sea-ice-extentconcentration/. Let me know if there are issues.

If this graphic is useful, I will add an version.

If you saw my post with the stamp of the rock form known as “The Pants”, here is a photo of a Polar Bear dwarfed by it, seen through its legs. I had the wrong lens on and couldn’t get a photo of the entire formation and bear.

With high impact extreme weather happening all around the world, I've put up a post with weather and climate highlights in Alaska this month.

Throwback to summer. I’ve applied for some funding to upgrade my drone so here’s a shot with my Mavic 2 Pro. A panorama of Qajuutinnguaq down Adams Sound from home.

Latest 'cloud-free' mosaic from MODIS satellite imagery showing the lack of sea ice and thus greater areal coverage of open water (compared to past decades). Note also the large phytoplankton bloom and drifting wildfire smoke.

Simulated reconstruction of July sea ice thickness since 1901. Large interannual variability & widespread thinning in recent years.

Information about this data set is available at https://doi.org/10.1175/JCLI-D-19-0008.1. Note that it is only updated through 2010 due to ERA-20C forcing.

Animation of polar stereographic maps showing Arctic sea ice thickness for each July from 1901 through 2010. There is a long-term decreasing trend in ice thickness during the last few decades.

My fellow partners in crime aka esteemed colleagues probably already know about this event, but I've just read about it for the first time.

A marathon in (or the ) would be a tempting place ... if it weren't for the hefty price tag, which ranges from USD 21,000 to EUR 55,000 depending on the location and date 😱
