Study: Weather linked with sentiments expressed on social media

Study suggests Facebook, Twitter sentiments correlate with weather patterns – no mention of climate linked sentiments

Sentiments expressed on Facebook and Twitter may be associated with certain weather patterns, according to a study published April 25, 2018 in the open-access journal PLOS ONEby Patrick Baylis from the Vancouver School of Economics, Canada, Nick Obradovich from the Massachusetts Institute of Technology, USA, and colleagues.

Previous research has identified a potential link between weather and people’s emotional states, but which specific weather conditions trigger positive or negative emotions and how to measure these sentiments in an accurate and consistent way require further investigation.

To examine the association between weather conditions and expressed sentiments, the authors of the present study gathered 2.4 billion posts from Facebook and 1.1 billion from Twitter between the years 2009 and 2016. They analyzed the sentiment for each post using a special tool that categorizes posts based on keywords as positive or negative.

The researchers found that temperature, precipitation, humidity, and cloud cover each were strongly associated with an expression of sentiment, whether positive or negative. Positive expressions increase up to 20 degrees Celsius and decline as the temperature goes over 30 degrees Celsius. They also found that precipitation was associated with more negative expressed sentiment. Days with a humidity level of 80% or higher were associated with negative expressions, as were days with a high amount of cloud cover.

While the sentiment analysis tool used is imperfect, this study can help provide insight into how weather conditions might impact sentiments expressed via social media, which can act as a proxy for underlying human emotional states. Understanding the potential impact of weather on our emotions is important considering our constant exposure to weather conditions.

“We find that how we express ourselves is shaped by the weather outside,” says Nick Obradovich. “Adverse weather conditions — hot and cold temperatures, precipitation, added humidity, and increased cloud cover — reduce the sentiment of human expressions across billions of social media posts drawn from millions of US residents.”

Very interesting, but hardly new knowledge. Furtheer investigation is required. Please send more money.

Total waste of time and money. It has been known for years that weather is directly caused by comments on social media – see my study, send £££’s.

Bryan A

What they should have been studying is how negative messages about Climate change, like “Warmest Ever” or “Arctic Ice at Lowest Level Ever” or “We Have Only 2 Years to Change” or “Antarctica is Melting” or “Island Nations to Disappear From Sea Level Rise” and how the hopelessness caused by them directly affect social media posts.

Ah, but if the weather remains very hot and humid for an extended period, it can be a tipping point for people to start punching other people which leads to extremely violence, uncontrollable riots and lots of blood, guts and giblets. Everywhere. Hey, but as it’s really cold for April right now, we’re all chilled out (hence the expression). Can I have my grant money now. Oh, please.

We have a perfect example of that right here on WUWT, from a dear fellow skeptic just today.

A groundbreaking study. They clearly show the relationship between social media activity and the local weather.
Finally, we have a strong causative proof of weather patterns.
The old Yankee quipped “Everybody talks about the weather, but nobody does anything about it.”
Now we see that talking about the weather, at least on social media, is what causes the weather to change.
This opens up an intriguing possibility.
Could it be that the most dramatic weather phenomena of our times, CAGW, is actually caused by the researchers who study it?

Unfortunately your theory has a hole in it. I travel often to Las Vegas for business. I hear all the people at the gate and in the terminal excitedly talking about how much money they are going to win. Days later at the Las Vegas gate I see the same people ready to leave: sad, frightened about paying the bills and many wishing they never came! The “Inconvenient Truth” about CAGW applies to gambling, finances and relationships: there’s a big difference between illusion and reality!
It has been so cold around here I can’t get my early garden seeds to germinate. No matter how much I yell at the soil it just won’t warm up!

TonyL

The universe does, after all, have a sense of humor. Unfortunately, not a very pleasant one.
Witness CAGW, the researchers are terrified at the prospect, and that only makes it worse.
The same applies to Las Vegas. Expectations of great winnings and glory make huge losses inevitable.

No matter how much I yell at the soil it just won’t warm up!

You are doing it wrong.
Try kerosene with a big pile lawn/garden debris. Make a nice big fire and that will warm the soil up.
Better Living Through Chemistry!

I thought you were supposed to talk to your plants NOT yell at them

rocketscientist

It’s ok to yell at the dirt…. as long as your neighbors aren’t watching. (it’s best to just curse it under your breath)

Cape Town residents already know that mood causes weather. We were severely depressed as a result of the drought and water crisis. Lo and Behold! The depression became so deep that it started raining! (We’ll have to stay depressed for a while longer until the drought is broken)

I recommend a continuous loop of Al Gore movies with his dreary voice at a reasonable level. That should do it.

Like hitting yourself in the head with a hammer. It feels so good when you stop. Afterwards even the worst weather seems pretty good.

Great idea. Even better than re-reading 1984.

Leo Smith

Has it rained? Enough?

No. We need a lot more …

Crispin in Waterloo but really in Kempton Park

It just rained hard in Cape Town, and to put a negative spin on it, the radio somberly reported that the dam levels only increased 1%. You might have thought that reversing the downward death spiral of the stored water and driving it up 1% would have brought joy to the beleaguered, barely washed masses.
The guy who re-floated that big tour ship has a plan to tow insulation-wrapped icebergs to Cape Town. He says he can supply 130 m litres a day for a year from one of them. They will tow them to the currents that will bring them floating north. It is not even that expensive to do.

@ vuurklip …I made a prediction back in February regarding the Capetown drought issues, doesn’t look good in my opinion. I hope that you get the rains which are needed for your area. I would rather be dead wrong on this one, then proven right while people suffer.

What is the prediction?

Note that every drought period listed occurs after the solar maximum. Some of the droughts reach their end in the solar minimum period. Most of those droughts occur in what I would term as a cool trend, 5 out of 7. The last solar max was in 2014. The Capetown drought started in 2015. You can see from what I posted that many of the listed droughts start one year after the solar max.

Thanks for the info.
Rainfall in March was well below the long term average – in April it seems well above average except for Theewaterskloof – the most important dam! Where can one access the figures you have given?

Here it is. I came across this fellow’s site while reading up on the drought problem in your area of the world. …https://briangunterblog.wordpress.com/2018/02/14/capetown-rainfall/comment-page-1/#comment-108

Thanks!!

See, cats and dogs can get along, at times.

@ vuurklip …———————————————————————————
Here is a quick look at the Capetown drought record and my take on ‘Why’.

Drought yr …Sunspot Cycle …Solar Max …Solar Minimum
1851/54-4yr. #9 ………………….1850 ………..1856
1864/66-3yr. #10 ………………..1862/63 ……1867
1894/97-4yr .#13 ………………..1892/93 ……1900/01
1926/31-5yr .#16 ………………..1926/27 ……1932/33
1963/67-5yr .#19 ………………..1958/59 ……1965/66
1971/73-3yr .#20 ………………..1968/69 ……1975/76
2015/?? …….#24 ………………..2013/14 …….???? 2019/20?

My forecast, one more year of drought for certain, highly probable for 2
more years as this look like the mid 1960s as an analog, imo. This is
one of my forecasts, or my way of seeing if I am am seeing a good
picture.

My mood is significantly affected by weather, more specifically by light levels. Dazzling bright sunlight dramatically lifts my mood, makes me feel more positive, energised. Bright artificial lights help a bit when the weather is dreary, but they are not as good as the real thing. Just as well I live somewhere very sunny and tropical – makes me the happy person I am today ;-).

DC Cowboy

But is it your mood that affects the weather or the reverse?

Bright sunshine makes us squint which folks mistake for smiling. They smile back which everyone mistakes for happiness. We feel better due to squinr induced happiness.

Fen Tiger

Back in the day I worked with someone who had been at a very senior level in the British natural gas distribution industry. He said that day-to-day sales volume variations were correlated (much) more closely with the colour of the sky than with temperature.

Stevan Reddish

That makes perfect sense:
My experience from living in Montana was that on sunny days of, say 25 F, low angle sunshine streaming through my windows warmed the interior of the house, allowing me to burn less firewood. On the other hand, cloudy days of say, 35 F, with no sunshine warming the interior and with higher humidity giving the cold more bite, my wife always wanted the wood stove well fed.

Scientology would be a better fit

In the case of “WattsUpWithThat” which I see as social media, It is not weather but the climate that has brought us together. Why are we always confusing the two? Weather is whether or not it is going to rain. Climate is what is going to kill us next year.

Research suggests that when your home is destoyed by a hurricane, tornado or flood, it puts you in a bad mood

Mike Maguire:
Speculation on your mood when you’re a still in the house and die as result can only be found in philosophy and religion, Most indicate that you have transcended weather.

We’re having a heat wave
a tropical heatwave
the temperature’s rising
it isn’t surprising
she certainly can
can can

In the summer time when the weather is hot
You can stretch right up and touch the sky
When the weather is fine
you got women,
you got women on your mind

summertime…
and the livin’ is easy
fish are jumpin’
and the cotton is high

Summer lovin’ had me a blast
summer lovin’ happened so fast
I met a girl crazy for me
I met a boy cute as can be
Summer days driftin’ away
to uh–oh!–the summer nights…
* * *
it was a hot summer night and the beach was burnin’
there was fog crawlin’ over the sand
* * *
Runnin’ through this business of life
Raisin’ sand if I’m needed to
Ain’t so funny when things ain’t feelin’ right
Then daddy’s hand helps to see me through
Sweet as sugar, love won’t wash away
Rain or shine, it’s always here to stay
All these years you and I spent together
All these winters
couldn’t stand the weather

Sweepin’ the clouds away
On my way to where the air is sweet

How to get to Sesame street?

Talkin’ to myself and feelin’ old
Sometimes I’d like to quit
Nothin’ ever seems to fit
Hangin’ around

Sunny, yesterday my life was filled with rain.
Sunny, you smiled at me and really eased the pain.
The dark days are gone, and the bright days are here,
My sunny one shines so sincere.
Sunny one so true, I love you.

Why many people travel from cold countries to Thailand spending big money in tickets if >+30C is so terrible? Maybe, just maybe people wanted not +2C, but rather +25C, or even more. I firmly believe human is not built for temperatures below +28C. Not that I liked to sleep in +28C. I’m so accustomed to cold my limit appears to be at +24C. After that, I will have harder to sleep.
By the way, it is not the humidity unless in very hot weather, it is the rain. If it is raining the whole day, it is boring. I should know. We joke on Bergen here.

Jer0me

You do get used to higher temperatures for sleeping, but 30C is too high imo. A good breeze (natural or artificial) helps enormously, though. In India I sometimes used to soak a sheet and sleep under it with the fan on high. When it dried out, I woke up, then repeated, all night.

commieBob

I remember being ecstatic the beautiful bright sunshiny day the temperature went up to -15°F.
People in hot climates go about cheerfully on days that would leave me cowering miserably in front of an air conditioner.
It would be interesting to know if the study’s results change depending on local norms. In Inuvik the average high in July doesn’t quite reach 20°F. The mean monthly sunshine hours for December are zero. Based on the study you would expect the residents of Inuvik to be terminally depressed … but they aren’t. 🙂

Look at songs above, why do think they call Bankok?

charles nelson

Judging from the snarling that went on at WUWT yesterday…I think ‘sunspots’ or maybe ‘lack of sunspots’ has a major influence on the tone of social media interaction!

Jer0me

Days with a humidity level of 80% or higher were associated with negative expressions, as were days with a high amount of cloud cover.

So in my home town in tropical Australia, with continual high temperatures and high humidity, people should be miserable, but they’re not.
Mind you, back in the UK where it’s normally cold and damp, they are a miserable lot…

ozspeaksup

Im one aussie that would be miserable up nth qld or topend wa
the dry heat inland and most of the lower areas is fine
add humidity and i have to go sit inside with a fan on
age sure has an effect on handling heat as well
i hated the cold when younger but oddly(to me) i seems to cope better with cold, in apite of arthritis now.

Sara

I want $$$$$ just to have to wade through a study like that. Send me money. I want cash, and I want it yesterday. Cash will make me happy. Yes, it will. Cash, and a new car and pancakes with lots of butter and maple syrup.

Sara, you have no ambition. Lesser studies provide naked Chippendale strippers who make the pancakes and drizzle the maple syrup very, very slowly.

Creepy. Are we all OK about that?

Enquiring minds…… or do they?

based on keywords as positive or negative

Is anyone gonna speculate what it might make of Monty Python, the English Sense of Humoour or my mood (of sillyness) right now.
My little story,a sort of antidote (that is NOT the right word but..) to Tom Of Florida came from working outdoors on the engine of my previous little truck. Afternoon of New Years’ Day 2014 in Cumbria.
A dry/reasonable day became cold and the mizzle (cross of mist and drizzle) started. I got thoroughly damp trying to finish the job before dark.
For 2 days after, I had something akin to a cold or flu – but it wasn’t. No headaches, no high temperature but just generally felt ‘crap’ Physically and mentally.
Just out of something to do to try diagnose this thing – I discovered my blood glucose numbers were off-the-scale. Dangerously high. I have never had such a fright in my life.
Morning of the 3rd day and I awoke feeling fine, the thing had gone and my blood glucose was back in the normal range.
So, would this ‘special tool’ (chuckles to the point of tears) have diagnosed that?
sorry.
Peta control yourself!!!!!
(A small part of what’s got me going is (yet) another epic Met Office fail. They predicted one month’s worth of rain over London and the SE including me here and – you guessed- it is turning into One Great Big Phat Zero)

Ben of Houston

Well, there are so many confounding variables that it’s not really measurable (you’d also have to correct for sports scores, exams, and life events as well as sarcasm and wit), but just comparing the ratios of positive to negative posts should give an indication that there is an effect.
The biggest question is the purpose of this. was it just to test the old saying of rain making a day a day blue? It does not seem to be a reasonable use of funds.

Retired_Engineer_Jim

Did they get their Facebook and Twitter data through Cambridge Analytica? I guess this use of ostensibly private data is OK?

Bruce Cobb

People have always liked carping about crappy weather, but now, there’s a new twist, because True Believers use it as a proxy for “climate change”. Indeed, you can usually tell a True Believer (but you can’t tell them much, pa-dum), by the way they complain, especially about warmer weather, heavy rains, etc. They will also often complain about things like insects, and how they are supposedly “getting worse”, “fewer birds”, and a whole host of things the Climatists have tried to connect with “climate change”.

Original Mike M

I’ll take the position that the correlation is clearly indicating that sentiment on social media is controlling the weather, (can I get me a consensus here?).
If we are required to prove that CO2 is not controlling global temperature then it seems fair to me that they should be required to prove that sentiment on social media is not controlling the weather.

Thomas Homer

Original Mike M – “… we are required to prove that CO2 is not controlling global temperature …”
Aye, there’s the rub. We are required to prove that something which cannot be measured does not exist.

Well, don’t under estimate the ability of mankind to be able to waste time and money. I know webcammers who everyday log in to a site just to be able to try the bot trivia quizzes and are proud of their increasing point total. I know of many chess players who have bought a computer chess software package who spend most of their day playing against someone else’s computer chess program and each one of them is proud that they win games against each other but they are all deceiving themselves because they are attributing their programs win as if they themselves had accomplished the win. The list is endless including responding to this article like I am doing now wasting my time. On that note it has been studied that grief counselors are a waste of time and money. Protecting “hertiage buildings” are a waste of taxpayer money. Every heritage building eventually falls down if not propped up by taxpayer money. Who defines what heritage is? Modern art is also a waste of time. Throwing paint at a canvas has fooled art historians who thought that a painting was legitimate. Again the list is endless. Perhaps 40% of government expenditure is a complete waste of money. I worked in government for 30 years so I know a few things. This latest posting article is just another prime example of the folly of humankind. AAAAAAAAAAAAAAAAAAAAAAAAAAAgh.

Nope.
It is the opposite: weather patterns correlate with Facebook, Twitter sentiments. Another proof of CAGW/sarc

GregK

“Positive expressions increase up to 20 degrees Celsius and decline as the temperature goes over 30 degrees Celsius. They also found that precipitation was associated with more negative expressed sentiment. Days with a humidity level of 80% or higher were associated with negative expressions, as were days with a high amount of cloud cover”.
That suggests the entire humid tropics is a sea of negativity and misery.
