Another month has passed and so here is the updated Arctic sea ice volume graph as calculated by the Pan-Arctic Ice Ocean Modeling and Assimilation System (PIOMAS) at the Polar Science Center: A month of somewhat slowing extent increases has been reflected in the PIOMAS sea ice volume model output....

Yes, ignore him (here). You can go to his YouTube channel if you're interested in what he's got to say.

Another late update. Apologies.

I will write a new update this weekend. Sorry for the delay.

Thanks, Lowenan. I don't know about forever, but I am going to try and step it up again for the 2018 melting season. :-)

Nice expansion of what they already had there. Thanks, John.

Chances are high that I will be covering next year's melting season, so traffic will probably pick up then. Any thoughts on providing context for the max-min graph? I had already renamed 'max-min' to 'total melt' (as it's much clearer), but somehow uploaded the old version to this blog post. Fixed now. Here's the total freeze bar graph (posted earlier in April):

There are some excellent discussions in this segment of the Arctic Sea Ice Forum.

It was posted on Mongabay yesterday and written by Gloria Dickie. --- At 2017 minimum, scientists ask: Is Arctic entering the Thin Ice Age?

It's easier for him to ask here than on the ASIF, because he's been banned from the ASIF for asking so many questions, interspersed with idiosyncrasies like "people in very high places that were really concerned". I'm putting up with it because the blog is quiet now (due to my sabbatical) and I have a cold, and I think he means well. But not indefinitely, of course. Anyway, A-Team is doing high-level technical stuff on the Forum, the details of which are very interesting to people who know about these things, and the images are enjoyed by everyone. If you don't dig/understand it, that's your problem. If you want to criticize it anyway, your contribution to the ASIF and citizen science in general needs to be much, much larger.

Here's one tip from the ASIF that might be a temporary solution: I have the same thing - at least when I try to log in from the main page. Clicking through to the actual login page first, that works though.

Patrick, thanks for clarifying. I will ask Fred to see if he can solve this problem.

I occasionally get that timed-out message too. What I usually do, is refresh the page and try to post the comment again. Of course, always copy your comment before clicking the post button.

Have things improved? The ASIF is working for me. In fact, the https version should work now without browsers issuing security warnings.

But again, I don't know whether the ASIF is hacked for real, and if so, by whom. People are looking into it. Good news! It was a false positive, no hack. Forum is back up again! And is it possible that the Arctic ice will be able to find a new equilibrium where ice does not totally disappear in spite of temperatures increasing globally? Given that heat flows from the equator to the Poles (where most of it radiates back to space again), I don't think there really can be such an equilibrium as long as the atmosphere and oceans continue to warm up. At best, the Arctic becomes ice-free towards the end of the century after all, which would still be incredibly fast, in geological terms. And what is the influence of El Nino events on the Arctic ice? As far as I know, there is no proven direct link. But there may be indirect ones.

On topic: be ready for your words about upturns to be misused by the usual suspects. I try not to care too much about what the usual suspects do, because then I have to think about how I say things, thinking in gotchas and maximum effect. Before you know it, I'm a usual suspect myself. ;-) I'm just calling it as I see it, and try to be clear about my biases and motivations. If people then still want to hack the blog/forum I set up in my spare time, so be it. I think that in the long run they only hurt themselves, because being able to do such things, sets you up for lots of personal misery. Life is short and very easy to screw up. But again, I don't know whether the ASIF is hacked for real, and if so, by whom. People are looking into it. Oh yes, isn't the trend line the straight one and not the squiggly one? The squiggly trend line is the anomaly trend line, the straight one is the linear trend.

Patrick, thanks for the link. As far as I know so far, it's a possible hack. Maybe it isn't. If it is, I don't know if it's by someone with climate risk denier sympathies, or a Russian spambot, or whatever. We'll have to wait and see, and hopefully the ASIF can go live soon. John, I agree.

Absolutely, John. I didn't quite get it done this evening, but I will publish tomorrow morning.

2) PIOMAS only updates monthly. Is there a volume estimate that updates daily like the NSIDC Extent graph? Not in numbers, but there are two thickness maps on the ASIG (scroll down to the volume category). DMI and ACNFS. And this melting season PIOMAS is also updated mid-month, after special request. The numbers are posted on the ASIF (not in yet for this mid-August). But that's complete guesswork without previous sea ice concentration graphs to compare against. On the ASIG there are also Concentration maps pages that allows you to compare the current Uni Bremen SIC map with those of previous years since 2005. Check it out, as it takes a lot of time to update those pages.
