Science / Re: Trump Administration Assaults on Science
« on: March 30, 2017, 07:14:53 PM »
The climate office will probably be closed, but in the meantime, the term "climate change" is banned in all internal communication, according to a Politico source.

Energy Department climate office bans use of phrase ‘climate change’; The Office of International Climate and Clean Energy is the only office at DOE with the words ‘climate’ in its name, and it may be endangered as Trump looks to reorganize government agencies.

Sad to see science disappear from the local politics. Is there any reason to buy anything technical from US anymore?

Arctic sea ice / Re: 2017 sea ice area and extent data
« on: March 28, 2017, 07:44:50 AM »
Well I guess someone had to be the first to speculate on future behavior of Global sea Ice. Thanks Buddy for being the first bold one to spell out the dreaded 't'-word (tipping point).

Some notes.
1) The August 2016 would be very close to the maximum atmospheric effect of El Nino.
2) Large part of the (imo) naturally impossible deviation of last winter (starting from late October) was due to Antarctic ice melting way faster than usual.
3) Thus there could have been a tipping point for some part of Southern Ocean. I remember there was something odd going on on the region of Weddell Gyre.

This would be the Antarctic area to watch this (northern) spring. Has the Antarctic Circumpolar Current moved to an area it's not previously been? Thus the start of the freeze in Antarctic could be abnormal here as well

4) For me, the Arctic lack of growth in the autumn was pretty much what I'd expect of the WACC (and the theory of J. Francis of the diminishing temperature gradient between tropics and arctic).

5) From all of the previous. I'm not even sure we'll even see the first peak of the global graph clearly. The global graph could flat line all through this summer starting from June as the Siberian melt progresses.

An extreme scenario, but on these days they're necessary to be aware of.  Knowing you're much into politics, Buddy, I'm still of the opinion that Russians as people (and especially Siberian Russians) do not much care if their winters get milder. They might get a couple of ten millions of immigrants from south at some point, but that's an issue for the time it happens.

I'm keeping an eye on the spring progress during this post-El Nino year. I think the more pronounced swings in the extent and area of Arctic Sea ice since 2006 allows the speculations of general tipping points, but  for now i'm thinking these more of a local issue. As the weather gets stuck in one position more easily these days, the serious hobbyist of atmospheric science in me could say, the weather induced events unfolding round the northern hemisphere are of note and interest. I'm rather looking forward the time the idjit possessing The Button and his so called
friends get it. Not too much though, as their other views are also quite repulsive.

The rest / Re: Arctic Café
« on: March 26, 2017, 02:04:58 PM »
I would love to hear those sounds. Will be much more noticeable at night..
I think a pretty good imitation cn be achieved by taking a trayful of ice cubes, go to  really quiet place, record it. Then apply various legnths of echo to individual cracks...up to 4 secs, and amp up something like tenfold... I had to stop the recording early since akid asked her mother something 40 meters away. Possibly cannot try again this spring it's in the low 50s F here today

That I can confirm that the harbour is free of ice.

« on: March 26, 2017, 09:46:31 AM »
Mind you, these are of fresh ice melting in-place. If the river wasn't controlled that would have left for sea alredy. The lake instead is rather natural wrt ice. Tried to record sound of ice cracking but something went wrong. Nice to hear spring is progresaing, though. I haven't visited Baltic shore since the latest imges so don't know what's up in there.

And so it begins; the linked article is entitled: "Bill Would Bar Discrimination Toward Climate Change Doubters"; which could make evidence-based scientists guilty of hate crime if say they were to deny a climate change denying scientist (with research funded by the fossil fuel industry) a tenured position.

Well this sort of a bill would be a reason for this thred to be in 'science section. Of course no sensible university would obey this. They really want to dumb down north american citicens. Coal-communism, or fossilic fascism.

Oh, this was the 'validation of gcms'-thread. Sorry for the last one. Validation of gcms proceeds in many steps. Firstly, you gotta get the normal ghg-effect equations so correct that you get the surface temperature to rise from the non-ghg temperature of -17,5 c (or was it -18,5°C?) to rise to the observed preindustrial temperatures. There was a lengthy explanation of further validation steps somewhere, but not on computer so not going to find and summa4rize it right away.

(EDIT2: Some students I know are organising a climate lecture in York, UK. They already have a prominent denier and are looking for a climate scientist to counter him. I suggested Kevin Anderson but I don't think he's replied yet. Any other suggestions? I'll see if I can get help with the homework!)

What is the point of debating a Gish galloper?? It is almost futile unless the climate scientist is able for a Gish gallop of his own. Countering one by one the points of a Gish gallop is a waste of time....
Basically it could become a general lecture on AGW with regular disturbances of the stupidest student. This should end up (again) by the stupidest student thinking his views are reinforced, and the listeners (hopefully) thinking this guy should be expelled. The denier will prepare with talking point memo that might have one or two hard to explain points of discussion and the scientist requiring more time than him which the inane idiot will take as break of debate rules. The rest of the memo contains shouts that interrupt explanations of inconvenient truths by the scientist thus disrupting the potential for learning for people who aren't already convinced that renewable(well ok, also nuclear, with way less highly active waste) energy is the only viable option for energy generation and transport if we as a species do not want sea levels of at least 9 meters higher and "who anyway cares what happens in 200 years, and is it 200 or 400 maybe and J.Hansen is a retired loonie."
Oh, the times when talking of car and especially driver performances at the latest wc rally have taken over the discussion at the local bar that only infrequents engineers. I for one was glad to hear about the start of electric drive-train manufacturing start at the local car builder. Oh yeah. Everybody though admits you cannot get as far in a day by electric cars than by internal combustion engine and leasing a car for the summer vacation trip is beyond them. Nice.

This is starting to become a rant so I stop. Thank you for listening and remember the disadvantages of electric rail/cars and the intermittency of wind/solar.

Arctic Background / Re: Baltic Images
« on: March 19, 2017, 04:39:20 PM »
There isn't too much sea ice left here in easily accessed places so that couldve been the last image in this spring. Last summer I found a place where I could have taken an overview image of the opening message area, but that, in winter, would involve a 2-mile trek along icy rocks and cliffs so it's not likely I ever get there, in winter...

thanks, Neven. I had forgot this thread too so I posted one set of Baltic images to Arctic café :,179.msg105546.html#msg105546

Then there was the meltpooling image at,179.msg103093.html#msg103093 which is from the same spot (but southwards) than the last image on this thread.

The rest of the images at Arctic Café are of the river and of the lake so 'Baltic' doesn't apply for them.

Among other places, it looks like there is melting and thinning out of ice within parts of the CAA.

With current temps there, I doubt we are seeing any thinning out in CAA. More like the usual thickening-in I'd say.
Kara otoh is going south pretty quickly this year.

Oh, is the River Ob already in spring and flowing fast to Kara sea? The bay there could be an indication of that. The zero-degree fresh water from the river taking a toll on the -1 degree ice on the bay, possibly? The bay is somewhat brackish :


The majority of the scientists and engineers do not have the skills to be concise,  on target and quick on come backs. It is unfortunate...

Yep, it comes with the job description. Many, coming to science, are hoping to make a big discovery. On one short 'philosophy of science'-course I took the lecturer said on most lessons 'the first thing to doubt is yourself". There were several reiterations of this too.

Arctic sea ice / Re: 2017 IJIS extent maximum prediction
« on: March 19, 2017, 03:35:34 AM »
No mine was a fluke

At one stage I thought it was headed for 14m

The melt could be impossible to get a bin for.

Where to begin or end?
Fluke, beginner's luck, sensitive insticnt, lucky shot, call it what you will, but get three in a row as close people will take note... ;) I still remember when my second shot with a bow hit a 9 and the next 10 went right off the target :).

If you get many guesses on any poll someone is bound to be nearest and very close to correct. Or at least among nearest two. Add to that, most of the 127 voters did not announce their exact guess so saying some exact number in correct bin increases the chances to be nearest one.

In this sort of net poll, someone would have to do a list of the exact guesses and calculate the stats from those to get a more fair representation of the chances. Some people said specific descriptions of their guesses like 'low 14-14.25', but the calculation above doesn't note these at all. I just took the midpoints of each category and multiplied by number of votes to get the ASIF average.

Arctic sea ice / Re: 2017 IJIS extent maximum prediction
« on: March 18, 2017, 04:30:08 AM »
I chose 13.91 so wasnt far off for a complete novice just picking a number out of increasingly hot air

I included the extreme values with the values 15.125 and 12.375 and got the ASIF average to be 13.699803Mkm2, so that's waay closer. The ASIF erred by 178484 km2 to the low side so as a group this is one of the most accuratest values we've been voting for over the years. But as usual, some individuals (this happens because of statistics, too) are almost on the spot, 31710 km2 (pauldry600) doesn't even fill the State of Maryland! As a group though, we lost an Uruguay-sized chunk of sea ice. Well that happens. So what, if Missouri-sized slab of 2 meter ice goes missing in predictive polling, that's only ~1.3% error. You could say forgetting the Alps is significant, but the Alps are just a one mountain chain in the world, do you remember all the others (and remember to count in Antarctic sea ice max) ?? This result would have been approved to experimental medical testing with humans (death as a side effect has though a higher limit). Not bad I say. (please check this yourself before spreading the message of high accuracy of the forum members.)

(Edit:Hoping I don't have to do that again as the cracking is quite significant up there...

By looking only the past ten year average of c.14.404M the error would have gone up to near 3,8%, in contrast pauldry600 hit within 0.23% of the current maximum number. I know in biological systems this is nearly unattainable accuracy so the conclusion is we're likely dealing with physics.  Stretching to verbal extrapolation, I could say, in this case, physics was at least 2.5% more accurate than history ::) :P ;)

Arctic sea ice / Re: IJIS
« on: March 17, 2017, 07:02:40 AM »
The 14-day average change finally went negative so by my own criteria I have to say the maximum has been passed on the extent measure. 13,878,287 km2(March 6, 2017). Of course there's a possibility that export starts so intensively that this "true maximum" will be surpassed yet, but I'll take that as a measurement error.  ;) ;D :P. But that is still a low extent. And the rotation of Beaufort gyre seems to be (at least temporarily) reversed so it might be this maximum still is not the high value for IJIS.

 ::) i wonder if they include continental drift in natural variation?  ;) 8) :P thanks for the link to stoat and the paper, always nice to see scientific papers without paywall. I haven't read it yet, but admit that arctic amplification is not entirely anthropogenic. Of course the usual suspects take this on a ride. Wouldn't be surprised if the study does not say what the usual suspects say it says.

Marked decrease of dinoflagellate abundance during PETM observed. As oceans were this warm, it would mean vast areas of tropical continents were too hot for multicellular life at this time. I guess this would mean even the rains were too hot for plants. Sorry no link for the actual paper (partly based on models) but here's the press release and abstract about this.

Thanks Crandles for following up the calendar month numbers.

Weekly number for the Last Week
Feb. 26 - Mar. 4, 2017 is
407.37 ppm
which is 3.29 ppm more than Weekly number 1 Year Ago, Feb. 26 - Mar. 4, 2016
404.08 ppm
which in turn is about 5.2% more than Weekly number 10 Years Ago, Feb. 26 - Mar. 4, 2005
384.04 ppm

So 5.2% in nine years. that is 5.7‰/year. That doesn't sound too good. Maybe we should abandon CO2 stocks?

The beloved Trumpistan leader notifies his subjects from this day on use of microwaves is forbidden. Be it cooking, cheffing, or measuring ice with chinese adjusted satellites.

There is an association between El Nino occurrences and increases in yr/yr monthly CO2 emissions rates. The most recent El Nino demonstrates that relationship.

What's more troubling is when one observes a CO2 spike with no associated El Nino. The chart illustrates the relationship between ENSO 3.4 (El Nino La Nina and monthly NOAA/ESRL CO2 increases. There is more at:

Eyeballing this char seems to indicate based on past correlation of spikes that our current spike might not be over nor at its peak. I hope tbat's not the case.

Mauna Loa record would say january global values of change since last year are still large but that february would be a bit lower. Not that the Mauna Loa and Globe are exactly synchronous and of the same magnitude always. It's quite a good proxy for globe but deviations do occur, if I remember correctly. A4R, would it be possible to have the global record extended to the start of Mauna Loa record with some degree of accuracy? Proxy-based extensions of existing records are anyway done on many locations wrt paleoclimate, so this might be applied here too?

Oops, the last of the graphs would state this is already being done.

What's going on?

The same as in the nearby lake? That is, 1-2 mm of defrosted snow? Lucky watery reflection on the instrument on board?
So, basically, the sat. sees a layer of melted snow, which is now water on top of the ice, instead of the ice underneath, and makes it appear to us that the ice is gone?
That's my guess. It could be the angle of the sun has to be just right for this to happen, and the sat would have to pass in the right time of the day. Not sure. Fairly sure this isn't yet meltpooling, but would be the same thing that happens when frost on grass has melted just a bit.

Posting the link (again) to ScioD for who want extensive reading on the subject. In short, some the latest models DO take post-glacial rebound into account, some are concentrating on the role of WAIS during deglaciations and Dansgaard-Oeschger events, and some are slightly modified Milankovich-style theories.

There are better (most) and poorer (7-8) chapters, but the author gives links on about everything.

All quite interesting. Of course the positions of the planet's glaciers are now different than in the previous de-glaciations, so direct comparisons may not apply.

I live a bit south of the southern border of the subarctic climate  ( and have occasionally also had trouble with selecting a proper thread. Mainly this would happen with ecological articles from the popular press, it's easy to open a thread in Science-section if there's a Nature-article to present along with the rest of the text.

There's the 'AGW in general'-guideline on the main page on the forum, thus some of this stuff has gone to 'Consequences' and some to 'The rest' (some personal observations). Some still in the 'Cryosphere' if the thing in question concerns only winter... I'd could suggest opening a 'Changing seasons'-section under 'AGW in general', this could be a place for ecological/agricultural articles round the world. There's still pretty wild nature even in Europe. At least some of my posts would have been in this instead of elsewhere.

I don't care much of the politics, but the politics (rather, 'pollutics') currently (also here in Finland) is such that... (sigh...). Expecting myself to still do some rants of that too, though most of that should likely indeed go to 'foúl language'-thread...

The fact is the Arctic change is still a symptom of the general AGW. That this may change sometime in the future (loss of summer sea ice, permafrost, meltdown of Greenland, changing weather systems) at least for a while, and thus humanity would become a subservient
(could be a wrong word) influence in the equation of planetary radiation balance, doesn't change the fact the changes we started are global in nature. On this forum, this would mean, to me, a large expansion of the AGW in general section but how to do this best is beyond me. For a temporary solution the bolded proposition above could do, at least I could have thrown in there some phenological ( maps and seasonal diagrams of various critters and animals, maybe also of smaller vascular plants and trees. (oo, there's an arctic pine (or was it some other species) in Lapland that has increased it's yearly growth 300% in the 2000s, clearly this means CO2 is good for plants)

<Buddy> at least you should replace all the 'millions' with 'thousands' when talking of volume... But that's an error seen also done by others... Would have to check your points one by one but yes, the situation is such that if not this year then the next high heat year (my guess 2021-2022), however far in the future the next big release of atmospheric insulators (aka greenhouse gases happens (+++ENSO or some other large ocean surface heat anomaly), the Arctic ocean could have ice only in the form of icebergs and spilled icy drinks from the vessels travelling there.

I haven't acquainted myself to Ole Humlum' stuff. Presuming he's one of the great number of people who like to think most of everything humans do is 'natural' so he'd be discounting quite a bit of human influence. "I just happened to find this petrol station and my credit card fits in the slot and I get this stuff that burns so brightly i'm blinded by it"-type of denier, possibly. Has someone classified deniers into sub-types? Could be an interesting (thpugh completely futile) intellectual exercise?

Posting this here too, probably this is already referred to somewhere else on the site too. A state of the art public and general lecture on state of climate change study and on metastable icy regions of the planet. Dr. Jim White speaks.

Are we turning to the tailwind or are we on the last turn before that on this climatic journey on spaceship earth?
