This reminded me of this old xkcd.
It can’t be that cold, they’re naked except for the hats!
Btw, we don’t even get much ice anymore here. 20 years ago, as a child, i could go scating on the frozen lake.
Now he can’t even remember how it was spelled.
Follow up: https://xkcd.com/1322/
Wait hold on, he could be spelling it right and we’re the ones not getting the point.
YOU’RE IN THE JUNGLE BABY
YOU’RE GONNA DIIIIIIE
This will be especially true once Alaska becomes warm enough to support a jungle.
70 degrees of what? Freedom?
Temperature translation for non-Americans:
70°F ≈ 21.1°C
50°F = 10°C
20°F ≈ -6.7°CI posted this further upthread, but it bears repeating. Don’t manufacture fake precision. Nobody says “It’s 69.8 degrees out”, just like nobody says “It’s 21.1°C”. 70F is 21C, and if you need more precision than that, it’s not in a Lemmy comment!
if you need more precision than that, it’s not in a Lemmy comment!
If you need more precision about less precision?
That’s in a Lemmy comment! 🤓
I get what you’re saying, but there are threads on Lemmy that get super technical. Those do require quite a bit of specifics in some cases.
Super-technical threads need to respect significant figures. Your result can’t be more precise than your inputs.
Fake precision? It’s a simple unit conversion.
This is a sciency thing about precision. The classic example is the old joke of “this dinosaur skeleton is ten million years and two weeks old - they told me it was ten million years old when I started, and I’ve been working here two weeks”, the point being that the age was roughly ten million years, not tell million years exact to the day.
Scientists talk about “significant figures”, the number of digits that are actually important and not just extra zeroes, e.g. 10000 has one (probably!) and 0.0103 has 3. So when someone says it’s 70°F they are probably rounding to two significant figures, so for the conversion you should do the same, i.e. 21°C. If they said it’s 70.0°F then you’d convert to 21.1°C.
Sure, it’s a simple unit conversion, but it’s a rough figure. When I say it’s 70 degrees, I’m not saying that it’s 70.000 degrees.
What I’m really saying is that it’s about 70 degrees, so the true temp could be between 69.6 and 70.4 degrees (I don’t know, I’m not looking at the thermometer that closely).
69.60 F = 20.89 C 70.40 F = 21.33 C
Turning my “70F” into “exactly 21.11111C” is just silly.
Did no one else learn about significant figures in grade school?!
-40
I’m in the US and it’s below freezing here & now. Do I need to translate that somehow?
it didnt say degrees whatre u on about?
unless you cant use context clues to decipher a unit but blaming another country for existing isnt a proper exuse for your own shortcomings.
It’s slightly below freezing and snowing here in West-Central Indiana. We haven’t been above the 50s yet this Dember.
Now admittedly, the 50s in December is not the same as when I was a kid and we are definitely doing great damage to the Earth’s climate and biosphere, but saying kids aren’t going to grow up because of it is a bit hyperbolic.
but saying kids aren’t going to grow up because of it is a bit hyperbolic.
Yes. It’s a facetious tweet… You are in a meme community. You’ll have to get used to seeing jokes here.
The Skywalkers always regretted their appearance on Maury
You’re right, we do get used to seeing information deliberately exaggerated for comedy and then taken seriously. It’s why the internet is so braindead.
No need to discourage people from getting the facts straight. Just agree and move on.
We’ve been over 50 north of you in southeast Michigan multiple times this December
Of course they are going to grow up. 20 years are nothing. Those are issues that will only start to get serious after that time. Which is exactly why so little is happening now.
I’m in Indiana and it was 60 fricken two days ago.
Hush
I think the guy above you was calling out the fact that the picture in the post is using a temperature scale that is only used by very few countries as if it was the default for the Internet.
Have fun in the water wars, kids!
I can’t remember where I first read it but I’ve agreed with it ever since: “My retirement plan is dying in the potable water riots.”
The only time water will be a problem is when someone’s using weapons to force others away from sources of it. In terms of desalinating water and delivering it to thirsty people, that’s something the market is perfectly capable of attaining. It’s always profitable to meet unmet basic needs so any water holes will be filled automatically. And that’s in the worst case scenario, where people are just buying trucked in water. In most places there will be actual plumbing serving people.
Great. Thanks. Now I can’t get the image of Kevin Costner pissing into a funnel out of my head.
Me either :-)
Where’s the water going to go? It’s in the water cycle, if anything is going to rain a lot more and a lot more violently, and in areas it shouldn’t be raining.
If it’s contaminated we should be fine collecting and stiling rain water.
“Water is a rare and precious resource” when not talking about habitats, is a silly hyper capitalist argument meant to stoke fear and panic purchases.
It is in the water cycle true, but where it is in that cycle and where it ends up are both critical to our long term industrial agricultural water use.
We need far far more water than collecting it from the rain would provide.
The coming water wars will be fought over the rights to the dwindling supplies…
Those Saudi Royal horses need to eat
A lot of water used in agriculture is actually from underground water sources that refill very slowly. Once we run out of those, many of the things we do can’t work anymore.
About 10 years ago it didn’t rain in Central California for 2 straight years. Imagine that, but with the ground water gone, and places water is traditionally piped from saying “no more”. Millions of people would die.
When all the rain falls in the ocean, it’s effectively gone.
Lmfao you really think the people with money won’t take control of natural resources?
That’s a pretty bad assumption considering they already have. Companies across the planet have already taken over most natural resources and will defend them with militaristic ways.
Water is already privatized in a lot of areas.
Just a heads up, but most states have laws that guard against rain water capture. For example Colorado only allows 2 barrels or 110 gallons per year!
https://extension.colostate.edu/topic-areas/natural-resources/rainwater-collection-colorado-6-707/
Avg US citizen uses 100 gallons/day
The water goes into the ocean and then we cant drink it anymore, is that not obvious??
Wait, why can’t we drink it anymore? Do you really think there’s no way to purify and remove things like salt from water? Please tell me I missed the satire.
It’s not that we can’t remove the salt, it’s that electrolysis to remove salt from the water is very expensive from an energy perspective, which makes it expensive from an economic perspective too. A massive spike in the price of water would cause a widespread crisis impacting every corner of the economy.
Also, building out the infrastructure required to do electrolysis on that scale would take a lot of time and resources on its own.
The word you are looking for is electrodialysis. And that’s not the only method. Reverse osmosis, distillation and nanofiltration are other options. Also, you mention having to build out infrastructure. You must not be aware of the 16,000 desalination plants around the world already.
This shit is exactly why despite having hated growing up in the frozen tundra… I’m now staying. Its not worth giving up at this point in society.
Been a…something… guys. Best of luck to you in the climate wars.
May the odds be ever in your favor.
You do realize that we won’t be free of the effects, right? Where do you think all the climate refugees are going to go?
Obviously… that’s why the first sentence I wrote was that I was staying up north….
We’re coming to you. We’ll settle in arcologies at the poles, where it’s still cool. Let the machines run all the industry in the sun-baked deserts of middle earth
Arcologies, sigh, thats the dream ain’t it. At best were wgtting Stargate slave society, at worst Metropolis. Neither is something I much want.
Climate controlled rolling arcologies. Maybe we’ll get some kind of fusion laser that can freeze the water in front of the city as it rolls across the ice.
But what if I like my freezing weather at home?
That’s ~21 degrees in non-freedom units from someone who has to do this conversion a lot.
Also, that’s pretty normal summer temperature if you are from the Southern hemisphere.
If we are being really pedantic, the freezing and boiling part of first paragraph is only true under sea level atmospheric pressure, so technically, you can’t really relate these quantities with the given information in the first paragraph either.
But I don’t think that’s the point this exerpt is trying to make.
Unless stated otherwise, you always just assume 1atm of pressure.
Yeah but if you’re boiling your pasta and you live a few thousand feet above sea level you’re gonna want to give it a bit more time since water boils colder up here.
~Who the hell times how long their pasta takes to boil? You just go until it starts making noises.~
Edit: woopsie…that’s not what they said. Colder - so it takes longer for the pasta to cook. My bad.
You should re-read what they wrote because that’s not what they said.
Oh yeah…thanks for pointing that out. I’ve been fighting some nasty cold/flu/covid thing and clearly not reading straight haha.
I like beeing pedantic. Please proceeed.
A calorie is not a metric unit but the joule is, 1 calorie is approximately 4.2 joule. A gram of hydrogen does not exactly have 1 mole of particles. The historical definition for the mole was the count of atoms in 12 grams of the ¹²C carbon isotope, which is slightly different.
The historical definition for a mole is a little underground mammal. Then you science geeks decided to just screw it all up because you couldn’t be bothered to make your own word. A molar’s a mole tooth, dangert!
A pressure which, funnilly enough, is not in fact 1 bar (as one would expect) in the metric system but rather 1.013 bar.
Now that’s a big middle finger.
One oz of water heated 1 degree F is 1 BTU. Boom just as easy
But this is clearly written from the perspective of someone who lives in a climate that used to be solidly below freezing all through the winter months in the northern hemisphere. Now snow seems like a distant memory from childhood.
21°C/70°F is a normal winter temperature where I’m from in the southern hemisphere 🥲
And right now it’s summer… let’s put it this way, lately it’s been over 40°C/104°F for so many weeks in a row that, when temperatures dipped to 33°C/91°F, it felt cold… and to think it’s only going to get worse going forward @_@
I call them Generation Last
The crazy part is I have friends who are well aware that the world is completely fucked and they are still making new children.
The cute smile, hugs and sex are pretty convincing 😪
EDIT: of my girlfriend, you sick psychos
Don’t have sex with children
😩
This is lemmy and you expect us to believe girls are real?
Bruh…
Then they are narcissists, plain and simple. Looking in the mirror saying “yeah I wanna see more of that”
Yeah we should all totally give up any hope and stop having kids.
Yeah we should. Today’s children are the last generation
Want to make a bet? I jest, obviously, since neither you nor I will be around to see how this all plays out in the end, but I am serious in my assertion that regardless of what lies ahead, humanity will not become extinct on the basis of climate change alone. That’s the worst sort of alarmist defeatism. You’ve basically given up ahead of time, before the real struggle has even begun.
You do you, but I am not done fighting and am not about to admit defeat and retire into self-fulfilling capitulation. I don’t want to accuse you of cowardice, but in some ways that’s kind of what I see.
The German equivalent of JustStopOil is called the Last Generation (or letzte Generation). The official name is like the last generation that can hold up climate crises, but the implication is clear
I feel like kids being born now will have a mostly “normal” (from our perspective) childhood and early adulthood but they’ll age up in an increasingly screwed up world. The generation after that is fucked.
That’s a quaint and hopeful take on it
I’m seeing geometric progression, positive feedbacks, and we are almost out of time
70 degrees in Dezember around here would kill most people, since it’s only 30 degrees below the boiling point of water.
Ah, being intentionally obtuse.
There are actually more layers there than just the obvious one…
I think you mispelled December as a reference to something but I dont know what
Came out half in Portuguese, half in English.
Well spotted.
I live near the arctic circle… it’s usually -40° right now… it’s actually +5°C today.
T-shirt weather in late December… wtf humanity
Yeah I never expected a nice day in December to bring such existential dread.
I’m not as far north as you, but we’re also having a super mild stint. Normally have a couple feet of snow right now but it’s rained for 3 days. Last December we had the same thing. Year before that we had about 2-3 feet of snow and highs of -10°C.
It’s gotten to the point where I can’t even rely on weather reporting to give me current weather. One day a couple weeks ago it’s -20 but the Weather Network said it was 0… That was rude. I’m thinking of setting up my own weather station.
I live close to the Arctic Circle as well and it’s +2 currently. Two weeks ago it snowed like a meter in 2 days. I’ve seen enough snow for this winter.
My neighbour was mowing his lawn last week (he’s retired). Usually we’d be shovelling by now.
I find it funny that you decided to include in your comment that he’s retired, it doesn’t add anything.
A little colour to help paint the picture.
But it explains, doesn’t it? Retired guys: always doing yard work, and fussing with their properties. I swear I just see them walking around with various tools all the time.
We have had almost no snow in BC this year. Northern BC is in severe drought. There isn’t even enough water to fill the recently completed highly controversial site C dam.
Basically that means we are going to have the worst fire season we’ve ever seen, sorry america but the smoke alone will ruin your summer too
Even fucking Haida Gwaii is seeing some mild level of drought right now. This shit ain’t right
You should look at the winter that recently ended in the southern hemisphere - record ice shelf losses during winter, record high temps in Rio and other cities. In winter.
And it’s just getting more and more brutal.
didnt it hit 90 or a 100 or something in Rio, during winter?
https://www.dailykos.com/stories/2023/11/17/2206375/-Heat-Index-in-Rio-de-Janeiro-hits-137-3-degrees-Fahrenheit?pm_campaign=front_page&pm_source=trending&pm_medium=web (this is during the ‘spring’ - our fall - and includes the heat index).
For their winter - on Aug 27, Rio witnessed its highest temperature of the winter, reaching 39.2°C
https://en.mercopress.com/2023/08/27/hot-weather-hits-rio-de-janeiro-this-winter
for winter, these temps are just bonkers.
sorry america but the smoke alone will ruin your summer too
Gosh dang it! In 2020 the fires turned our skies dark red, and there was ash falling from the sky. I don’t want to relive that. I couldn’t go outside for longer than about 2 minutes without getting a headache.
Drove through New York in June this year.
I think you drove through a dystopian movie set in NYC.
What’s the difference between reality and fiction?
Lack of flying cars and replicants.
Enjoyability
Great pic
I can’t take credit. Stole this from a news article, but that’s exactly my view when I was driving through there that day.
“That unapparent summer air in early fall”
- “That funny feeling” by Bo Burnham
“The slowly comprehending of the ending of it all.”
Hate when it rains during winter time

Lil kids talking about “when I grow up”. Man it’s 70 in December you ain’t growing up lmao
It was good while it lasted.
It was okay at best lol.
Was it?
We were over due.
That’s pretty normal for the southern US. I’ve had several Christmases that were 85 degrees even.
