On worldview, to the right of the screen there's a measuring tool where you can create a freeform by selecting random points on the screen and it directly gives you the area.

Arctic sea ice / Re: Re: The 2020 melting season
« on: July 07, 2020, 09:18:24 AM »

Light (or lack thereof) is constant. Both are above 0C and will melt. Will they melt at the same rate ? No. The tray in your closet will melt faster.

Yet the temperature just above the icecubes will be the same in both cases. You just took down your own argument...

look at the past 24 hours video. it was blown away by wind.

Sure looks worse than previous years. Mark Parrington from Cams is tweeting about this :

I think the place where we are easily misled is the constant messenging about Arctic amplification which does not highlight an important exception. AGW is not materially increasing average surface temperatures N of 80N during peak melting season. What's happening outside the core is interesting, but largely irrelevant to projecting the season minimum.

the fact that temperature doesn't go up does not mean that there's no energy exchange

In a place like Siberia, you may have a 100k km2 land area immediately adjacent to the Arctic where the 2m air temp is all heated to 20C+.

One does not see 2m air temperatures over the open ocean approaching 20C in areas adjacent to the Arctic ice. The 2m air temps over the open ocean are moderated by the sea surface temperature and by definition the SST's adjacent to the ice are close to zero C. 


But heat is not only temperature. I think humid air over the ocean packs a bigger punch than warmer dry air.

no worries. I just read that we are actually below rcp 2.6 so nothing can happen...

These high gains in extent and area are becoming an event.
But too lazy to look for the why of it all. Armageddon can wait until 2020.

Just wondering if low snowcover in lower latitudes and Europe suggests WACC is currently in reverse, i.e. extra cold in high latitudes, warmth in lower latitudes.

wouldn't it have something to do with the shape of the stratospheric polar vortex which is divided into 3 parts for some time now ? just wondering ...

HEADLINE: Atmospheric Angular Momentum (AAM), a measure of how fast the atmosphere is spinning relative to the Earth's rotation, is a complex variable that can offer insight to particular flow configurations within the atmosphere.

lol, I think he meant this one :

Don Vito Corleone: What have I ever done to make you treat me so disrespectfully? If you’d come to me in friendship, then this scum that ruined your daughter would be suffering this very day. And if by chance an honest man like yourself should make enemies, then they would become my enemies. And then they would fear you.

In the last interglacial, temperatures in the Arctic were much higher than today, and the world didn't end.


The world won't end. Just the humans and most species on it...

First, you need to agree on the definition of a BOE. especially with regard to the timeframe.

     The world needs the people informed by this forum to spread the news of this existential threat to family, friends, neighbors, colleagues, and politicians.  Please talk about it, that is the essential first step.   
 

absotively true, but everytime I bring this up, I see eyes rolling up. People just don't want to hear about catastrophe unless it's on their doorstep...

D8 at EC 00z op. Godzilla high at 1043 hpa over the Arctic basin... :o This will be a complete assault to the ice. Just wonder how much longer the brown ice in Chukchi Sea will linger?

My understanding was that high pressure means clear skies so high insolation. But is 1040 hpa worse for ice than 1030 hpa, all else being equal ?

Think you're looking at a closeup of the roof, that's not a tower but an air vent or chimney pipe or something.
