Arctic sea ice / Re: The 2020 melting season
« on: June 01, 2020, 09:31:13 AM »
Alu - great videos thanks - but it would be handy to know dates as it rolls around - can't really even see start and finish as the first one (whole month) looks fairly similar throughout.  If its a compilation of frames maybe for example rather than 31 flashing numbers - maybe use week 1 / week 2 / week 3 ?

Just to add my tuppenceworth … MANY thanks Neven over the years - it can't be easy & must take a lot of time. 

Arctic Sea Ice is a great daily update on the key climatic driver(s) as the world changes so fast.

Its great if the many threads can stay on topic - so we can look at the ones we want (and ignore the ones we don't want to read).   I admit I do go elsewhere for e.g. politics / Coronavirus etc.

Whoever takes over - best of luck - "Bon Courage" - Oren & co-moderators and I am really pleased you can step up to the plate - it's a testament to Neven's hard work  - and even handed moderation - that the forum has retained so many great contributors, and indeed still welcomes both newbies and experts (real and claimed). 

Good idea to spread the load - and I guess if other specialist areas crop up - maybe others with the skills / knowledge base could cover them, since moderating a thread does need a good understanding of it.  As you may have guessed from my "handle" I had many years in the oil industry for example - though now (happily) out of it !

All the best Neven!

Archimid - thanks.    You say:

Given the measures taken to date, the final numbers for the initial wave shouldn't be much larger than 118,288. An order of magnitude larger at most, as long as quarantine is maintained.

Surely an order of magnitude = 10x is MUCH larger?

When they initially made these claims - 100 - 240k assuming quarantine continues - they implied it might be 2million plus if nothing is done - i.e no quarantine.  Presumably the messy situation with some states not on "stay at home" - or very late - and some exempting places of worship, result may well fall in the middle somewhere.  :(

Waiting to hear if France is going to be on total lockdown (as of midnight Saturday we are already on partial lockdown).  Pictures of people frolicking and picnic-ing along the Seine and in Bordeaux yesterday havent given a good impression. 

Shop stock emptying fast - certainly no toilet paper, pasta or potatoes.   Still some baked beans though.   Macron on at 8pm / 7pm UTC... :-[


Wipneus - thanks for all the efforts - how about a double thickness line for the current year - or a dashed version?

Equally maybe the ones say before 2010 could be finer / dotted lines so that even if they are  roughly same colour its easy to spot that they in a different category?

Keep up the great work, geron and Juan...sounds like a 70s pop group
But I thank you for the thankless (not anymore) daily task!

Plus one - many thanks for all the regular data - hard work and much appreciated !

Certainly quite warm here in South-West France, no sign of freezing conditions yet (projection 4 - 12 deg c for next 10 nights/days), but has been crazy wet. 8)
Seasons greetings and thanks for the informative, regular posts. ;D

So that explains it!

Maybe something like this ….


As we are putting pet irritations here - how about the dates...

Is today the 27/10/19 - or 10/27/19 ?

I find Day / Month / Year easiest (and perfectly logical as they are ascending order of size) but the US standard seems to be month / day / year for some reason  -  and of course that is the one overlaid on many of the downloaded images.... 

Obviously when speaking you could equally say "27th of October" or "October the 27th"

aaaaagh - off now for a free extra traditional hour in bed (or 0.041667 of a day....)

Thanks Stephan - timely reminder....

I think there is something to be said for viewing the melt and later freezing as being behind / ahead x days. 

Most of the statistics are km2 above / below average / record - whereas maybe a good way of looking at it is that we are 10 /31 days behind in the freezing  compared to average - and will probably have 10 /31 days "less" freezing as a result.

Don't mind - I was interested in the philosophy - personally I like all of the "data" posts - but I only do a "Like" for a particularly insightful comment /post (which could be embedded in the data post - or a separate one on that thread or elsewhere) - I guess its up to everyone to decide.   

I can't see / dont know if a particular post has been liked - that would soon bump the numbers up & probably skew things, and there is a certain irony in "Liking" a report of say a fall of 100k in sea ice area.  Its usually easer to make the decision in the Arctic Sea Ice Images section!

Facebook goes a bit mad with "likes" so very happy not to go down that route!  ;)

Aren't the "likes" for individuals doing exceptional posts - probably posts above and beyond the "normal" ?  We cant see the likes related to each post I dont think
Think they were only introduced in 2018 too ....   

If we all did a "like" for each time a set of graphs or statistics is posted for example they would soon add up but not sure they would mean as much imho.

I think the daily updates of several slightly different data sets are great - and my thanks as well like Phil42 to everyone that does them as it takes real dedication!  :) 

I think the smoother 5 day trailing NSIDC is handy as well then we have the monthly data & occasional trailing year data.  That's probably enough different timescales (certainly for me to get my head around).  I am sometimes worried that comparing todays data to historical "on this day" may be risky as there can be sudden jumps >100 occasionally which may skew the historical daily figs.

Sorry Tom - I dont think we should get into the perfection of predictions argument in this  data thread  though!  :(

Aluminium - though that is the measure of quantity of responses I am not sure that is the best indicator for the quality of the thread (or even level of engagement) - it may encourage too many off-topic posts or multiple (almost) identical posts - extra weather maps / speculation etc.

Gero:  ....and something very odd is going on.

Wondering what surprise(s) may be in store then.....

Dunno why it went tiny !!!

PETM - What do left and right sides represent?  Thanks

Antarctica / Re: Sea Ice Extent around Antarctica
« on: August 18, 2019, 09:03:29 AM »
- Extent LOSS on this day 37 k, a variation of 2 k from the average gain of 35 k on this day.

Is that GAIN, 72k or loss ?


Antarctica / Antarctic Expeditions
« on: February 11, 2019, 04:27:33 AM »
There doesn't seem to be separate topic for Antarctic expeditions - of which there have been quite a few recently.

Currently at least two major new ones -
A) Looking for Shackleton's ship in the Weddell sea &
B) the joint Thwaites investigation - multiyear project

We have also just had two one-man crossings of the Antarctic and the recycled Antarctic solar truck trip to the pole.

Links to current ones:
updates seem just in News section

for updates:

Aluminium - what do the different lines lines etc represent ?  I cant see a key to the graphs.  Thanks

Wow !

Or if you want to know how solar radiation with latitude changes with date see:

Others have posted similar ones - but as arctic circle is at ca 66deg north - this graph illustrates when incoming energy to the arctic drops to nothing.

Antarctica / Halley base shut down and new crack in Brunt shelf
« on: January 16, 2017, 06:30:16 PM »

The British Antarctic Survey is to pull all staff out of its space-age Halley base in March for safety reasons.
The highly unusual move is necessary because the Brunt Ice Shelf on which the research station sits has developed a big new crack.

Lets hope it can get fixed !
