This article claim ships will “be able to sail right over the North Pole” by 2050 due to warming, but at the same time say ship tracks will make more clouds and cool the Arctic. Of course, anything is possible with the help of climate models.
More ships and more clouds mean cooling in the Arctic
With sea ice in the Arctic melting at an alarming rate, opportunities for trans-Arctic shipping are opening up, and by mid-century ships will be able to sail right over the North Pole – something not previously possible for humankind.

One week ago on day 252 MASIE reported the lowest daily extent of the year at 4.43M km2. One week later the image above shows how the ice edges have refrozen and extended. Note also the significant snowfall both in Canada and Russia

Arctic sea ice has gone under the radar a bit this summer, with alarmists’ propaganda drawn to heatwaves elsewhere.
As sea ice extent draws close to its minimum, it looks like finishing well above the last three years.
Temperatures across the Arctic are now falling rapidly:

The results of their analysis revealed that warming in this high Arctic site had proceeded at four times the global mean rate calculated in other data sets. However, Ding et al. note that over the last decade (2005-2014), “the warming rate in Ny-Ålesund slowed to 0.03 ± 1.85°C per decade,” which is essentially indicative of no-trend in the data. Lead-lag analysis further revealed that “Ny-Ålesund and global temperature variations were remarkably consistent, with a lag time of 8-9 years.” Consequently, the researchers say that “the ‘warming hiatus’ many scientists [have] studied also appears in Ny-Ålesund, it just started later than [that observed in] other areas.”

Global temperatures fell back to 0.19C in August. This means the YTD average is 0.23C, putting them back to roughly where they were in 2002.
Arctic sea ice is tracking close to 2014, which finished with one of the highest minimums in the last decade. Current extent is well above the last three years.

Malgré des températures particulièrement élevées ces dernières semaines sur l’Hémisphère Nord, voire exceptionnelles sur l’Europe, le déclin des glaces de l’Arctique s’est vu ralenti.
Au 23 août, l’étendue des glaces de l’Arctique était d’approximativement 4.945 millions de kilomètres carrés. Des niveaux toujours particulièrement bas au regard de la moyenne observée sur la période 1981-2010 (6.866 millions de km2, soit un déficit de 28%). Néanmoins, ce niveau n’est « que » le 6e plus bas observé à cette date, très loin de la triste année 2012 (une superficie inférieure à 4 millions de km2 à la fin août). Une timide amélioration, puisque l’étendue de ces glaces avait alors été la 4e plus faible jamais observée sur l’ensemble du mois de juin.

Remember this? The ill-fated “Spirit of Mawson” expedition to Antarctica (in the Akademik Shokalskiy) that set out to bring attention to “global warming” only to be trapped in ice?
It’s deja vu all over again. (with h/t to Yogi Berra)

As the Arctic summer ice melt approaches its peak, we can say with high certainty that this year’s ice melt will extend the trend of a rebounding Arctic ice mass by another year.
Arctic summer sea ice now growing 12 years
Our Japanese skeptic blogger and good friend Kirye reports using the data from the Danish Meteorological Institute (DMI) that peak summer Arctic sea ice volume upward growth trend has been extended yet another year – now 12 years.

Arctic sea ice melt dropped to its lowest level since May 12 yesterday, and now the Arctic won’t be ice-free until July 20 of next year, 12:01 am.

Using data from the Danish Meteorological Institute (DMI), Japanese skeptic blogger Kirye just tweeted how Arctic sea ice volume has surged to the 3rd highest level in 16 years.

According to DMI, average Arctic sea ice extent in July is at its highest level since 2005.
With temperatures at normal levels, there is little prospect of Peter Wadhams predictions coming true this year!

Recently climate catastrophe non-believers have been pointing out that Arctic sea ice volume has been gaining over the past years and has not trended downward for some dozen years now.
And global warming alarmists have been very silent on the subject of climate change now that global surface temperatures have cooled and Arctic and Greenland snow and ice have rebounded.
Embarrassed, they don’t want to be reminded of all the absurd predictions they made 10 years ago, with some as recently as just five years ago.

Arctic sea ice volume melt rates have started to slow, with ice volume 4th highest since 2003.
Temperatures near the pole have been below normal almost every day this summer.

According to the Guardian (9 July 2018), there is a “global heat wave” going on right now.
In Siberia, the heat is supposedly “completely unprecedented” and will surely (we are told) impact Arctic sea ice — the habitat of the iconic polar bear. Yet a comparison of previous years shows little to no impact on sea ice: there is more ice present than there was in 2007.

Lately Arctic sea ice volume has been a topic which climate skeptics have been looking at quite closely.
According to Al Gore and a number of climate ambulance chasers, Arctic sea ice in late summer should have long disappeared by now, see here..
But then just a few years after, the Arctic sea ice area began to recover from its lows of 2007 and 2012. So immediately alarmists shouted that area was not really what mattered, but rather sea ice volume is what really counted. Okay, that made perfect sense. Mass is in fact what’s important, and not area, when worrying about polar ice disappearing …
