Arctic sea ice / Re: The 2020 melting season

Rod - thank you for posting that very disturbing image from the North Pile. Simply amazing. This is not your grandfather's Arctic anymore.
UCMiami - maybe not a scientist but excellent post.
Marcel g I agree, if this rotten ice survives it will be by the skin of its teeth. And it still needs to hold on for several tough weeks.
Glen K thanks for the data, I am betting melt ends later now than it used to, especially bottom melt. Surely also starts sooner, for the same latitude. This is not your grandfather's Arctic anymore.
     I can see why you would think that top and/or bottom melt would end later now given the continuing trend of global (and doubly so) Arctic warming.  But that raises a question of if that's true, why don't we see later dates for September minimum?

Because it still gets darker and cooler on the surface, I guess.

What about annual volume minima?  Have those been trending later as things warm up?

I don't think any of us is irrelevant.  And your concern is well founded.   

lots of very thin ice, much of it just rubble according to our eyes in the sky.  And, depending on which thickness map you look at the thick multi-year ice is pretty much gone.

Lots of warm water.

And August doesn't start until tomorrow.

I'm new here but I've been following the ice...pretty much since 2012, when it really got my attention. (thanks Neven)   And I'm starting to see why Friv' is so.... passionate.

It's looking like we're very likely to see a new record minimum this Sept.  I'm not imagining a BOE this year but some of these 'worst case' extrapolations look close enough to put us very close to one or another of the tipping points mentioned here.  The more I look at what's happening now the more worried I get about next summer.  There's going to be record amounts vulnerable of FYI.
