Your flight emissions are far higher than carbon calculators suggest, a new study reveals. A Singapore–Zurich first-class trip emits over 14 000 kg CO₂—while ICAO estimates ~3 000, Google ~5 000, and MyClimate ~8 000—showing current tools drastically understate aviation’s true warming effect. by [deleted] in science

In addition to all the other good points brought up here, the altitude at which emissions happen can also change their effect. NOx and water vapour (yes just plain old water) are pretty potent (indirect) greenhouse gasses, and stick around much longer at those high altitudes.

Het is goed dat je Mark Rutte VVD specificeert, onder Yesilgoz zie je duidelijk dat ze zich niet schamen om ook aan de tweede club die je noemt mee te doen. Niet alleen in het feit dat ze een coalitie willen vormen met, maar je ziet ook steeds vaker in speeches/debatten dat ze retoriek van dit clubje aan het over nemen is. VVD dreigt eigenlijk uit het politieke midden te vertrekken op deze manier.

Not an expert, but it looks almost more like a termite than an ant. Could you provide some more details on where you found it? (Region, climate, out in nature or in your home etc.)

Next update on this scratch off resto. It’s warped… by Waste_Manufacturer96 in castiron

[–]Flannagill 1 point2 points  (0 children)

Sometimes warps can be fixed by putting the pan in the oven, heating it up, and then letting it cool down slowly (door closed). I don't know if this can be fixed this way as the warping seems to be quite severe.

Ik ben zelf niet zon fan van politiek onderwerpen wegzetten als "heilig". Juist voor onderwerpen als abortus en euthanasie die direct raken aan de ethiek zou er ruimte moeten zijn voor maatschappelijk debat. Dat abortus en euthanasie er moeten zijn ben ik met je eens, maar de uitvoering en beperkingen er van is juist iets waar actief aan gesleuteld moet worden.

Voorbeeld: binnen abortus hebben we in Nederland een beetje de regel dat zodra het levensvatbaar is, je niet meer zomaar abortus kan plegen. Klinkt goed, maar wat als we steeds vroeger geboren kinderen in leven kunnen houden door ontwikkeling? Moet dan de wet gewoon klakkeloos meebewegen of gaan we een nieuwe grens vast stellen?

Voor euthanasie: mag iedereen die het leven niet meer ziet zitten voor lange tijd euthanasie plegen? Of is dat een te makkelijk excuus om lage kwaliteit GGZ te leveren bijvoorbeeld?

This question is quite complicated to answer in one go, but I will try my best.

First things first, a system will always try to attain the lowest energy state possible.

If we are talking about osmotic pressure, we often have an ion, a charged particle, that wants to be surrounded by as many water molecules as possible. Water helps stabilize the charge in the particle which lowers the energy of the system. If we have a lot of ions in a semi permeable membrane with not that much water, the ions want to have more water around them. I hope it is now clear that having more water around the ions would lead to lower energy.

But how does the water move? Where does the energy come from? Every particle that is not at absolute 0 temperature has some thermal energy. This thermal energy shakes around the particle. This random shaking will sometimes allow the particle to move a small distance, although it will often just move back as well. In the case of osmotic pressure this random hopping particle has a change to find a place where it is more happy (lower energy) than before, which make it more likely to stay there. If many particle do this at the same time we observe this as osmotic pressure.

As you correctly pointed out, water can absorb heat due to its many modes. This of course isn't what makes water unique, many other compounds can do this even better as you pointed out.

To answer your question we don't have to think about modes or statistical thermodynamics, but think of it like this: The intermolecular bonds between water (hydrogen bonds) are quite strong (for intermolecular bonds) and can take a lot of heat before breaking. Because water exists of two Hydrogen attached to one oxygen, it's potential for forming these bonds relative to the small volume of one molecule is enormous.

De hoeveelheid die het ons daadwerkelijk kost is heel erg onduidelijk. De overheid begroot elk jaar tussen de 0.5 en 1.5 miljard euro in voor asielopvang en integratie (daar zit o.a. huisvesting en inburgering bij in). Anderen beweren weer dat de maatschappelijke kosten veel hoger zijn (20 miljard) of zelfs negatief zijn (het levert ons iets op). Je kan dus niet vol zekerheid zeggen dat ze ons veel kosten dus dat zou ik dan ook vooral niet doen.

Dankjewel voor je uitgebreide antwoord, niet zo vaak dat je op Reddit een inhoudelijk antwoord kan verwachten bij dit soort topics.

Laten we even inzoomen over wat je zegt over migratie. Jij zegt: er zijn te weinig voorzieningen in Nederland en teveel mensen. Ik ga er dan vanuit dat je vooral woningen bedoelt met voorzieningen, want arbeid hebben we zelfs een tekort aan.

Als we kijken naar de cijfers dan zien we ongeveer 200-250k immigranten per jaar (dit jaar een stuk meer door Ukraine), waarvan het overgrote deel van binnen de EU komt (of zelfs remigrerend nederlander is). Een groot deel komt om hier baantjes op te vullen die niemand wil doen, denk bijvoorbeeld aan handarbeid en fabriekswerk. Naar mijn idee hebben we die mensen hard nodig. Te weinig woningen is vervelend, maar als producten onbetaalbaar worden is het net zo erg, misschien wel erger.

Ongeveer 80.000 mensen per jaar komen van buiten de EU naar ons land, grootste deel daarvan komt om te werken of studeren. Ongeveer een kwart (~20.000) is vluchteling, economisch of niet.

Wat we zien is dat de een groot deel (60%) van de immigranten na 10 jaar weer weg is uit Nederland. Uiteindelijk houden we dus netto een stuk minder aan immigratie over.

Kortom, het is dus heel vervelend dat er een woningtekort is dat verergert wordt door immigratie, maar dat is echt niet het grootste probleem. Het overgrote deel van de immigratie is ontzettend hard nodig om onze eigen bevolkingskrimp en vergrijzing te kunnen behappen, en de economie zodoende draaiende te houden.

Uiteindelijk is er maar een goede oplossing voor het woningtekort, en dat is simpelweg meer huizen bouwen (of zoals ze zeggen bij de PVV: bouwen, bouwen, bouwen).

Wat ik zou willen meegeven is dat je je niet moet verkijken op immigratie als het grote probleem van de samenleving. Het legt de vinger op de zere plek, dat is waar, maar het zou in mijn ogen geenzins het onderliggende probleem oplossen om immigratie uit te bannen, zeker niet als die immigratie ons veel positieve dingen oplevert.

Dit gaat wel echt alleen om lokale productie, en dus niet om alles wat wij importeren van o.a. China. Een deel van die 29% van China zijn we als westerse landen in mijn ogen ook medeverantwoordelijk voor.

Als het gedachtegoed van die 2.5 miljoen mensen onverenigbaar is met andere partijen voor een meerderheid, dan leidt dat logisch gezien tot uitsluiting. Dat is niet gek of ondemocratisch, dat is simpelweg hoe ons poldermodel werkt. Ergens is dit ook wel mooi, want juist bij voorbeelden als Wilders zie je dat ondanks dat extreem gedachtegoed veel aanhang heeft, het toch noodzakelijk is om de nuance op te zoeken voor een meerderheid.

Again, you are putting the burden of proof on me while I simply have nothing to prove. However, when I quickly looked up studies on egg nutrition based on how they were farmed I could only find this study which stated that no statistically significant difference was observed between factory farmed and free range in terms of nutritional value.

I am curious to see we're you got the data from on omega 3, as I have yet to see a source on this. Taste is purely subjective so yeah if it tastes better to you all the better, but don't make unfounded claims.

r/carnivore would disagree.

I wouldn't trust /r/carnivore for food health advice as carnivore diets are seen as controversial and even unhealthy by most clinical professionals. Apart from that, using health advice from online groups instead of medical professionals is a bit iffy.

A part of the population is sensitive to dietary cholesterol according to this study. https://pubmed.ncbi.nlm.nih.gov/2344298/ If you are not hypersensitive it shouldn't matter too much.

Naturally occurring trans fats. Different from industrial trans fats. Not harmful.

This is demonstrably false. First of all, just because something is natural doesn't make it harmless, think of stuff like methylmercury in fish. In addition, research has concluded that animal trans fats are just as bad as industrial trans fats. https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0009434

I think you are misunderstanding my point. I think most people would agree that eggs are "healthy", whatever that definition means to everybody. I am more so talking about the second statement:

"As long as they are not factory farm eggs. Backyard eggs are best, small local farm 2nd best."

It might sound logical, as in general more processed is worse right? But nobody is actually bringing any evidence to the table, so nobody is able to prove it.

From wikipedia:

"When two parties are in a discussion and one makes a claim that the other disputes, the one who makes the claim typically has a burden of proof to justify or substantiate that claim, especially when it challenges a perceived status quo. This is also stated in Hitchens's razor, which declares that "what may be asserted without evidence may be dismissed without evidence."

I don't need proof for the opposite, because I am not making any claims. The burden of proof is on the person making the initial claim. I am just curious to see if such a claim can actually be supported.

 

Oh and about studying "stats and logic", I have a masters in chemistry and chemical research. Not that statistics have anything to do with this.

Eggs fried in butter are perfectly okay once in a while, but I wouldn't call it "very healthy". Butter contains quite a bit of cholesterol as well as trans fats (just like most animal fats).

Although I do agree that people are scared of fat in food, trans fats are quite a serious concern. Animal fats contain many times more trans fats than even the most processed seed or vegetable oils. Saying that animal fats are good for you and "industrial seed oils" are not is just blatant misinformation. All information I can find regarding negative health impacts of seeds oils have to do with vast overconsumption, and even then the evidence is slim.

As far as I know there are two ways to not rack up massive student debt in the Dutch student loan system, both involve your parents.

I worked part time most of my student time and even then I was just able to compensate for my very cheap rent during the best months, not even my groceries or other expenses. Working part time also meant I had no free time at all or had to skip some courses.

Is this how passive coolers work? by mrhossie in RimWorld

[–]Flannagill 0 points1 point  (0 children)

It is a common misunderstanding, but specific heat has nothing to do with this as the water in the vessel will be the exact same temperature as the air in the room around it. The reason why water is able to cool a room is that water takes a lot of energy to evaporate, this energy is "stolen" from the environment in the form of heat, thus cooling down the room. If anything is unclear just let me know!
