Of 'extreme' interest to me is this just released report.
It would seem as though my 'fixation' on the status of Ozone was correct after all!!
I had realised that the dropping of the levels of Ozone was attributed to these fluorohydrocarbons
With all the emphasis on the interactions between Ozone and these compounds, I had incorrectly assumed that someone had investigated the properties of these GHG compounds. It seems not…
Substantial twentieth-century Arctic warming caused by ozone-depleting
WWW.NATURE.COMArctic warming is attributed to GHGs and feedbacks, but the specific contribution of ozone-depleting substances (ODS)—also potent GHGs—has never been...and the total paper is here -
https://www.nature.com/articles/s41558-019-0677-4
It would appear that these researchers are seeing nearly 50% of current warming is associated with these compounds in the Arctic...
Does this explain why I have been monitoring the no longer decreasing trends in Arctic Sea Ice?

Todays snow cover is hardly changed.
Sea Ice shows moderate increases overall, with the exception of SOO.

To add a little more detail to the 'Ozone' story, I posted this on the climate change thread, which should give us all pause for thought. It comes from the lead professor of the project -
Interesting comments by Lorenzo Polvano the lead professor at Colombia University....
"The results highlight the importance of the Montreal Protocol, which has been signed by nearly 200 countries, say the authors. “Climate mitigation is in action as we speak because these substances are decreasing in the atmosphere, thanks to the Montreal Protocol,” said Lorenzo Polvani, lead author of the study and a professor in Columbia’s Department of Applied Physics and Applied Mathematics. “In the coming decades, they will contribute less and less to global warming. It’s a good-news story.”
My comments -
He seems to be expecting (anticipating/predicting) a period of very reduced warming, if not a cooling ahead, particularly at the poles, provided that these HFC's are brought under control.
It seems as though these compounds are easily detected with satellite monitoring, and unlike CO2, they can easily be pinpointed giving us an easy and quick method of stopping their production.
About half a dozen companies across the world apparently are involved and at least one has already been stopped(the largest producer - in China!!)..
With a 50% factor quoted for sea ice and a one third factor for temperatures, this paper should not be dismissed lightly.

The complete paper you refer to is available in the link posted by BFTV yesterday in the ‘New Research’ thread.
My reading of the paper, in its entirety, is that the purpose of the research was to quantify the long known of contribution of ozone-depleting substances (ODI) to Arctic warming.
As for the conclusions, my understanding is that the authors consider that if their research is supported by further research in this area, the implications are that the phasing out of ODIs will substantially mitigate the rate of Arctic warming caused by AGW.
I have not, unless I have missed something in the paper, read anything about anticipation of cooling of the Arctic.

Crazy cloud day!!
Slightly adjusted for contrast but not far off reality
Stunning sunset a bit ago with what looked like orange mammatus - unfortunately I was in someone else's car as a passenger and they didn't stop...
After a clear morning, these were the type of clouds I noticed earlier, with a few lenticulars as well, when returning home over the Cairn o Mount about 45mins before sundown. It was all quite interesting with pale orange/yellow/grey colours overhead. I also was unable to stop for pics.
Missed the actual sunset.

I was lulled into thinking, due to the bright sunshine this morning, a walk in the glens might be quite pleasant. It was, in fact, ‘B’ baltic in upper Glen Lethnot due to a stiff bitter wind and the sun dropping behind the hills around 2pm.
However, spent a ½ hour or so lower down, watching a very healthy-looking population of red squirrels. It was difficult to count the numbers as they dart about so quickly.

Grass frost hanging on in the shade, icy puddles and frozen windscreens this morning; temp 2C, nae wind while the strengthening sunlight brings a touch of warmth.
A good day for a walk in one of the Angus Glens.

It is all about watching and being out in the open/exposed to the elements during the weather for me...heat, cold, thunderstorms, severe gales or anything extreme. (I love to be in the thick of the action)
Causes of weather as we all know is the transfer of energy between the Sun, Earth’s surface and the Atmosphere. (Unless all the books I read in my early teens are telling lies! )
I am not one for worrying about anything else weather related...each to their own though. (We all have different preferences, viewpoints and have an interest in different areas of everything weather related)
Still a bit windy here today but bright and cool at 5c.
Have a good day everyone!
Diverse weather interests are not necessarily mutually exclusive.
My personal preferences are for spring with its freshness, long summer daylight hours and warm sunshine, although I don’t mind bright winter frosty days. However this does not exclude, as I rather simplistically state, an interest and curiosity in regard to the development of different weather scenarios.

Insane stuff between 3pm and sunset - absolutely blasted with hail just after 4pm.
I will give Storm Brendan 6 out of 10 for effort!
This is why I love the weather!
Ye can stick yer three days of lowland snowfall per Winter up yer backsides!
I love watching the weather too, but I also like trying to understand the causes of weather? A difficult subject for me.

Decent day here. Bit of a breeze but not too strong, largely cloudless therefore sunny, temp on the cool side but OK to be working outside with just a hoodie on over a t-shirt.
Just 'washed' my wife and my cars. Should get an extra couple of mpg out of them now as they'll be significantly lighter if the amount of muck that flowed off them is anything to go by. One of the few disadvantages of living in the countryside, especially at this time of the year, is the 'interesting' state of the minor roads as muck gets dragged off the fields.
For general info (I'm sure NL will be aware of this):
Under section 95 of the Roads (Scotland) Act 1984 a person commits an offence if they:
- are in charge of a vehicle on a road
- allow a quantity of ‘mud, clay, farmyard manure, or other material (of whatever nature) from the vehicle (or carried on the vehicle) to drop onto or be deposited on the road which would create, or be likely to create, a danger or substantial inconvenience to road users, and
- fail to remove the material as soon as reasonably practicable.
There are similar provisions in English law.

Am I really the only person on this thread who does not crave ten foot drifts?
I do (very occasionally) feel a wee bit guilty about this as I know many enjoy snow-sports and the ski centres are so reliant on decent snow falls for their existence.
I also wonder about the mountain hares and whether they have fully donned their white coats this year. If they have, to add to their troubles, without white hills they will be more vulnerable to predation.....and the ptarmigans.

Thanks for pointing this out, CMD. The squall line has just passed through here too, followed by a quite sudden noticeable drop in the wind speed, and a patch of blue sky. More rain on the horizon though.
On a brighter note, a wee Goldcrest has blown into the bushes, which means, of course, I shall probably now spend much of the day staring out the window trying to get a further glimpse or pic. Still, on a day like this there not much else better to do.

Yes, there were. The sky for a time was a very intense blue.
Nipped into the garden and took a quick snap.

Last time that gold-mine was prepared for opening in the 1990s, the gold price plummeted and all the equipment was left to lie around to rust for many years. The only gold-mine in Tyndrum since has been the Green Welly Stop - that must turn over a fortune as its mobbed on any half-decent day during the tourist season!
If gold prices are economical this time, it could be good for the local economy, but I hope environmental controls are stringent, particularly as the gold companies have had their eyes on other hills in the area too (Beinn Udlaidh, etc).
I know, and I do avoid that place when in the area.
Perhaps, this time round, the mine will make a positive contribution ( or not) to the local economy.
On a purely sentimental note, I would love a simple gold band of scottish gold.

I have never tuned into LBC (thankfully). I do, however, occasionally listen to the disgraceful and biased BBC.

Seems like you’ve tried to fight the machine HC... never goes down well
I remember the days when we could have a general chat in here and we also had the politics thread(s), it’s a shame they’ve smothered all of that.
And aye, weather is also pure pish. Nothing to add
Yes, but of course climate and politics are inseparable for now. General chat won't sort it.
In my view, NW needs to sort out the subjective seeds of doubt posted regularly on here together with blatant denier videos/posts. That is, if it wishes to remain a credible weather and climate site.

After a nice sunrise and a bright early morning, the weather has defaulted to grey stratus and dampness again. The ground underfoot is very wet and soggy, and I’m still feeling crap.
Apparently, Jess (doggie) trotted down the track and first-footed the part-time neighbours yesterday, on her own initiative I would add, but dragged in four, feet-full of mud onto their carpets in doing so. She did receive a custard cream though for her effort, so I’m told.

Actually, 'acclimatising' to the cold, back then, as you may remember, was tolerating frozen fingers and toes ankle deep in slush, frozen window panes etc because there was not an accessible alternative for many. It was not a virtue.

Unless of course, one happens to be on the Autism Spectrum...?
As I can't abide prolonged contact with natural fibres, 'nasty' articles of clothing (scarves, balaclavas, woolen gloves and wooly woolies) were always jettisoned, the second I was out of Mummy's sight!
That was January 1963, and little has changed since, fabric-wise!
I never mentioned any particular 'natural fibres' which as you have specified, affect you.
But what has that to do with sensible clothing layering in cold weather.
edit: I used to rebel, as a teenager, against my mother insisting i wear a woollen vest under my school blouse.

The discussion on here about detailed pros and cons of weather clothing is a bit funny and also quite vacuous.
Surely the most important thing is to wear comfortable and appropriate garments, whatever the weather, according to individual tolerance/fashion/ preference.
Personally, in the Scottish winter, the default is three layers in the morning which may be peeled off later should weather circumstances change.

^^ Yes and now steady drizzle hereabouts. Not very inviting.
Not been over the door since boxing day due to a flu-like illness and bronchitis, ( reminds me of NL's calves) nae energy now, and the septic tank is not functioning properly - I wonder if this is because of the high water-table. Anyway, a drain person is supposed to be coming today, but I'm not confident that he will actully turn up until later in the week.
Feel like cancelling NY.

Another mild, sunny day. Cloud cover increased late afternoon with some ground fog developing.
@Ravelin not seen any honey bees around, hope yours keep safe. Some of the bumble variety have been spotted out and about locally. A few little ‘clouds’ of annoying midges have hatched in the garden over the past few days and are keen on homing in on my face and neck.
@Northernlights Still very soggy underfoot here. I noticed neeps were being lifted manually here a couple of days ago, maybe in respect of an increased demand for Burn’s night suppers?
