The whole situation with climate change feels so hopeless.
post
Some reuters reporting here.
Including...
Prolonged bouts of high temperatures in China have challenged power grids and crops, and concerns are mounting of a possible repeat of last year's drought, the most severe in 60 years.
China is no stranger to dramatic swings in temperatures across the seasons but the swings are getting wider.
On Jan. 22, temperatures in Mohe, a city in northeastern Heilongjiang province, plunged to minus 53C, according to the local weather bureau, smashing China's previous all-time low of minus 52.3C set in 1969.
Since then, the heaviest rains in a decade have hit central China, ravaging wheat fields in an area known as the country's granary.
These few sentences really capture the horror of "climate change", that so many people overlook. Yes "average global temp" might increase by 1 degree celsius, but the really immediately terrifying part is changes to large weather patterns that provide a foundation to gargantuan food production industries.
I live in Western Australia. It's a large state perhaps 3 times the size of texas, but it's very arid and mostly desert aside from the south west corner in which there's a "belt" of land with appropriate conditions for cropping in which 18 million tonnes of grain is grown each year, of which 90% is exported. Suppose this year the state receives 30% less rain, then next year 30% more. Suppose that halves production this year, and washes away some of the dry top soil next year. Hell, we might even receive more rain but just a few hundred kilometers from where it usually is.
Point is, even a mild interruption to established weather patterns is going to have a huge and detrimental impact on human agriculture. It's terrifying really.
For those wondering, one degree celsius increase means every kilogram of air has at least increased by 1°C. The specific heat of air is about 1158 J/(kg*C). Now that might not seem like a lot of energy, in fact 4g (one teaspoon) of sugar has 68,000 J of chemical energy.
The thing is, you might have noticed, there's a lot of air around us. About 5.14 x 10^(18) kg of air. So when you take a pretty normal number and multiply it by an insanely huge number, you get an insanely huge number. That's about 5 exajoules of energy. That is the total energy consumption of the US in 2021 for four million years. Or in sugar terms, equal to the energy of sugar if you converted a little over half of the Earth's entire mass into sugar.
We hit that additional amount of energy in our atmosphere in 2017.
The air increasing by 1⁰C isn't too crazy.
The ocean increasing by 1⁰C is an insane nightmare. Do you know how massive a heat sink the ocean is? For it to change, even by 1⁰, is terrifying.
And we're gleefully adding thermic energy to this constantly at a rate of about four Hiroshima bombs every second.
Reposting my comment from another similar thread ‘cause I think it’s kind of important to add.
Ok, so it doesn’t mention wet bulb temperature anywhere, so I went to figure it out. The first thing I was surprised with is apparently most of online calculators don’t take in values higher than 50C.
I couldn’t find the exact data about humidity for that day, but it has been 35-40%+ at a minimum for most days in that region, sometimes even reaching 90%.
So, 52C at around 40% humidity is 37.5C in wet bulb temp. The point of survivability is around 35, and most humans should be able to withstand 37.5 for several hours, but it’s much worse for sick or elderly. 39 is often a death sentence even for healthy humans after just two hours — your body can no longer lose heat and you bake from the inside. That’s like having an unstoppable runaway fever. And with that humidity it’s reached at 54C.
We’re dangerously close to that.
An absolute death sentence for folks without air conditioning or another means to stay cool.
From what I know the critical wet bulb temperature is ~31.5°C. it was from a study done last year.
https://www.theguardian.com/science/2022/jul/31/why-you-need-to-worry-about-the-wet-bulb-temperature
It’s a bit different depending on your health and all that. But 35 WBT is a definite point for everyone (since our bodies run at 36–37C). Kinda like the difference between “some will die” and “most will die”.
From @beigegat's article it says that from real expieriences it's 31.5C
The oft-cited 35C value comes from a 2010 theoretical study. However, research co-authored by Kenney this year found that the real threshold our bodies can tolerate could be far lower. “Our data is actual human subject data and shows that the critical wet-bulb temperature is closer to 31.5C,” he says.
I mean to say that the wet bulb temperature at which most will die is ~31.5°C, the gaurdian report I linked is saying that the 35°C number comes from a 2010 study, whereas the findings of the 2022 study found the number to be much lower ~31.5°C.
It’s probably a measure for persistent temperature then. Like, if you lock someone in a room at that temperature (or if it wouldn’t cool down at night, for example), then that person would be dead no matter what after some amount of hours or days.
35 is more of a real-life guideline, since it does cool down at night and you don’t need to withstand this temperature persistently and indefinitely.
And for the last several years there have been lots of places that exceeded 31.5 WBT during the day. Hell, you can probably find several places with that WBT right now. But since people don’t drop dead immediately and need time to heat up, it’s still survivable.
Think about it in terms of a 2D graph. You need to know the duration in addition to temperature to gauge survivability. A million degrees is survivable for a femtosecond, 35 for an average earth day, and ~31 indefinitely.
People saying:
"Voting doesn't matter. They're all the same." "Things can't be solved because the global elite won't allow it" "I don't have to do anything because it won't matter" "This is all big industry's problem, why should I do anything"
have been manipulated/influenced/radicalized by a combination of paid media shills, RW billionaires and Saudi/Kremlin/Iranian propaganda.
Snap out of it and let's all pitch in to save our children and world.
Voting matters, but unfortunately it appears to be an incredibly sub-optimal solution for dealing with climate change for the following reasons:
- Just because you can vote, doesn't mean that the option you need is even on the menu. It often isn't.
- Through hard work you can get the option on the menu, but that doesn't mean your politician won't do "deals" after they are in power.
- Lobbyists get access to politicians 24/7 and have a lot of influence, you have one vote every 4 years;
- Even if politicians do what you want, it is unlikely that your country by itself will make a difference, this is a global problem.
Meanwhile we are all fucked. It is likely too late already for preventing severe climate change. Our only hope now is geoengineering. The USA and EU are already considering blocking the sun.
The people who (rightly) have a sense of urgency about this are taking more radical action. They are blocking roads and throwing soup at famous paintings. These are desperate acts that seem rational in the face of the horror that we should strive to avoid, but the majority opinion of our species seems to be that these people are "too radical" and that common folks just trying to get by should not be inconvenienced, and that these radical eco-terrorists should be thrown in a cage.
To be honest, I'm not sure that our species deserves to survive.
Agreed, at least in principle - but your statement is so reductive it really could be said about anything.
It's so hard to motivate people to vote, people are exhausted and finding ten minutes in the day to feel good about oneself, much less performing a (seemingly futile, thanks to those poisonous ideas you've mentioned) civic duty is bordering on impossible. When 1 in 15 people in the UK need drugs just to keep their desire to live one more day in check - and a good chunk of the remaining population from that statistic are barely holding on - fighting the futility for someone else is an insurmountable goal.
I don't know if we can afford to wait for climate to get worse for people to take action. People are dying preventable deaths, if it weren't for the very evident effects of man made climate change being politicised or obfuscated, maybe it'd be just a warm Summer in Europe right now.
How long can we wait for a peaceful solution to form?
If we don't wait - how many heads would we need on pikes next to Mortimer Buckley or Larry Fink before we start seeing positive change? When would be the tipping point for the guillotine to become the most ethical solution?
Sorry, I'm rambling. I just feel so hopeless sometimes, and putting a X in a box 2 or 3 times a decade doesn't do anything to make me feel like we're making progress...!
Voting is still good, but it's the bare minimum. Not everyone has the time, but if you do, you should try to advocate publicly, and preferably in a group. Just like with unions, collective action is more effective. If I give feedback to my city individually, I'm a data point. But as part of an advocacy group, they reach out to us.
Well it's been fun y'all, cya in the wasteland, better watch your water.
My aim is terrible. I really hope I don't have to actively recycle urine.
Just piss with VATS
You mean the same water that's so contaminated with forever chemicals that multiple governments set recommended limits for safe fish consumption?
Hahaha....we're fucked.
For those interested:
"A new study has found that consuming a single fish from the Great Lakes is equal to drinking a month's worth of water contaminated with high levels of "forever chemicals."
(The recommended amount of some species of fish is now 0 in lake Michigan.)

Have you ever had a friend or relative who was just in such poor health, who you basically expected to keel over and die any day now? If so, you probably know what I mean when you eventually just accept that the person you once knew is already dead, and all that's left is a husk that's just riding out the last bit of momentum they've got until they fade away. And then when they finally do die, it doesn't even hurt, because you've already had time to grieve and process your emotions in advance.
That's kinda how I feel about the earth these days. I feel like the earth is on hospice care, and at that point that we're just making it as comfortable as we can for it to die.
Maybe that's a little melodramatic. But it really does just feel hopeless these days.
It's not Earth that's in trouble...
If it's any consolation. Earth, as in the spinning ball of dirt, will be just fine for many more millions of years. Humans, and other animal species, on the other hand are not going to be fine if the trend continuous.
Dunno, I find it kind of consoling in a meloncolic kind of way.
There's too much red in this picture. They really should use another baseline. If red would start only at 40 Degree Celsius, the globe would look much more welcoming.
Look, I'm just trying to give productive feedback.
Except China is proud of their red.
I have a friend with two daughters in their late teens, early 20s. I asked him the other day how they felt about climate change. He said they believed it was happening, but they don't think it's nearly as bad as "the media makes out". He added, "You know, we went through the Cold War and fear of nuclear annihilation and that didn't happen, so..." We were interrupted then so I didn't get to yell at him. But I think a lot of people think that way. Pffft, probably won't happen, news orgs exaggerating for clicks, someone will fix it etc etc. While shrugging at all the floods and fires and storms happening around the globe, and booking a cheap flight to Malaga. It's exasperating!
I know china wants to out do us on everything but fuck China maybe don't reach for the stars on that specific metric.
"Global warming is a lie"
The world is a ripe tomato.
Man, that must be hell, it's literally death valley temperature since they were the same temperature this week. Kinda ironic how death valley name was because the dudes who were stuck finally left saying "goodbye death valley", and in the future it'll literally become death.
I think we’re gonna need a bigger scale.
I love that they just have to make up colors now since the previous spectrum is no so inadequate
"Its always hot in summer"
The melting point of rubber tires is around 371°C or 700°F
They soften much earlier, though. And there's also the friction of moving against the road.
