            Sulfur can counteract warming (although not the carbon dioxide itself obviously). There was a brief period, right before the world stepped back from releasing sulfur into the atmosphere, when our carbon dioxide emissions were completely countered by our sulfur emissions, when it comes to global temperatures only.

          LOL, there is nothing racist about it, neither Poland nor Czechia are really into environmental enforcement against individuals, and you can definitely smell it in winter. As of now, "small sources of pollution" (e.g. mostly individual homes) are at least comparable to industry when it comes to releasing bad stuff into the air.

            It's the same in Latvia. Riga wants to set up a zero-emissions zone and a toll to enter the city center, but won't ban open stoves or solid fuel burning, which pollutes much more than cars in winter.

      I think it’s topology (concave) + widespread poor heating methods in the agglomeration + a very bad day + inefficient combustion engines.

      I’d maybe include accurate measurements. The government isn’t trying to hide that and doesn’t have the means to, and highly quality sensors are widespread.

      There are many houses in Poland that are using coal heating, and unfortunately a lot of people burn there their thrash. Kraków is surrounded by smaller towns and villages, where single family houses are common. To make things even worse, Kraków is in a basin, which makes the air flow even more difficult. If you add there years of city mismanagement when it comes to air flow, you land in such a situation

      From this source: https://www.iqair.com/mx-en/newsroom/krakow-among-top-10-mos...

      "Krakow’s pollution stems from a mix of local and regional sources. A primary culprit is domestic heating, the burning of coal and wood in older, inefficient household boilers and stoves remains widespread in the Małopolska region (1).

      Car traffic also adds nitrogen oxides and fine particulates, exacerbated by an ageing vehicle fleet. Topography and meteorology worsen the problem, Krakow sits in a basin-like region prone to temperature inversions and limited ventilation, allowing pollutants to accumulate.

      Additionally, emissions drift in from surrounding municipalities and industrial zones, making regional coordination crucial to air quality. Despite a solid-fuel ban in the city since 2019 and the replacement of many coal boilers, compliance is uneven and some residents still use banned fuel."

        The issue with solid-fuel ban is that its banned only inside of the city itself, not in the surrounding towns

      I live in Ostrava, some 160 km away. Entire Upper Silesia is a bad place for air quality in winter, it can often be seen on continental maps as a sore red spot.

      Fortunately most of the coal burning is gone, but individual people still burn all sorts of shit in their homes. PET bottles etc.

      • nephihaha an hour ago |

        • inglor_cz an hour ago |
          The official term is a Basin:

          https://en.wikipedia.org/wiki/Ostrava_Basin

          We tend to suffer from "inversions" here, and way back in the coal times, the air quality used to be comparable to London during the Great Smog of 1953. Nowadays it is better, but still quite bad compared to rest of Europe.

          In December 2024, I traveled from Ostrava to Warsaw and back via train, so through both Czech and Polish Upper Silesia. The Silesian part of the journey was a pea-souper, like riding through a yellowish cloud. (Warsaw itself had crisp chilly air.)

  • dmos62 an hour ago |
    Warsaw is top 15, Krakow and Warsaw are the only European cities in the top 15. For some added context, it's around -10 degrees celcius there right now. I don't know why Poland stands out here, but I know that older residential areas burn wood (in other Eastern European countries as well), because that's just how you heat an old house: these neigbourhoods are horrible to walk through in winter, because the air just stinks of smoke.

          If the somehow-trendy wood-burning stove a friend has recently had installed in the UK is anything to go by — and it was expensive — then "pretty clean" is relative. The air stinks outside his house, and the air stinks inside his house. I don't understand the appeal at all.

            But dried wood burns really clean, absolutely no smell INSIDE the house (wtf?!) and outside you see a thin whisp of smoke from the chimney.

          • dmos62 8 minutes ago |
            Fancy is subjective, but I wouldn't call a burner whose air is fed from the inside fancy. Even if you have a good chimney, but your burner interfaces with the inside air, presuming the house is relatively air-tight (built in the last 15 years), you'll get smoke inside when you use it, especially while the chimney is cold, because there won't be enough draft to pull the smoke out of the house. Where I am it is forbidden to have such burners in a new construction.
      • dmos62 an hour ago |
        Not sure what your gauge for bad is, but low-temperature burning of coal and wood, which is what you get with cheap wood heaters, produces smoke that is definitely polluting and unhealthy. You can get a wood burner that re-burns well and is very efficient and burns the smoke so completely that you mostly get CO2 and water vapor coming out of the chimney, but they're expensive.

        Care to share more about trash burning? I'd be surprised if people living in Krakow or Warsaw commonly burn trash.

            Also one thing to note is that if pollution is bad in general then nearby fires and local sources of pollution will be much more noticeable. At least in my experience it seems to keep the pollution closer to the ground. Like if you are walking around a city with a lot of traffic on a day with bad pollution you will basically smell car exhaust all day whereas on days with low pollution even with the exact same amount of cars it will be much less noticeable.
        • Tade0 12 minutes ago |
          It's people from surrounding areas who are experiencing energy poverty. City buildings typically have either central heating or gas furnaces.

          A common sight in my area at this time of the year is a senior person driving up to a community dumpster in an equally old car with plates indicating not being from around here and looking for loose pieces of wood - typically furniture.

          The sale of furnaces that would even fit something like this for burning was banned in IIRC 2018, but there's a backlog of still functioning ones that are used.

          Anyone trying this in a city would have the authorities called on them, but deep in rural areas few care.

    Few years ago Kraków has forbidden the use of solid fuels which improved the situation significantly. Days like today are happening much less often since then. Moreover, Kraków has probably one of the densest network of pollution sensors in the world, which is why we talk about it at all. There are places in Poland that are much worse off, but there's not that much data to back it up.
    • scyzoryk_xyz 32 minutes ago |
      My understanding is that the problem is exacerbated by the shape of surrounding terrain and atmospheric conditions. I.e. the city is in a cavity and on cold days there is a mass of high pressure that pushes all the smog down.

      But you are correct I believe (hailing from Wro here) - there have been many countermeasures implemented and cities are packed with sensors. Only so much can be done.

    • praptak 22 minutes ago |
      To be exact: the problem here is fossil fuel and wood being burned in inefficient furnaces/stoves/fireplaces where the fuel doesn't fully burn. There are efforts by the government to replace them but they aren't super effective yet (random example: https://um.warszawa.pl/kopciuchy).

      For the industrial scale fossil fuel furnaces this problem is solved already (they are obviously still bad because of their huge CO2 emissions but that's a different problem).

We theorized that the smog's mainly from residential burning of coal, but of course who know's what's in the stove.

    All I know, is that it smells really unhealthy, and the smoke coming out of houses is a deep, black colour, almost like oil.

      There's an interesting coping mechanism (verging on the conspiracy theory) popular on some Polish forums, namely that the abysmal data comes from abundance of sensors combined with them being placed (by whom and why? here's where the conspiracy part kicks in) in the most polluted spots.

        Until recently, I've been a smog-skeptic; I figured it must be an overblown issue, as regardless of what the digital sensors and pretty graphs say, having spent almost my entire life in Kraków, I never saw it, never felt it. Still don't. Air in Kraków feels perfectly fine to me. And every time I saw someone complain, it was because of "see the PM2.5 PM10 thru the roof omg zomg!", not any actual health-related issues or discomfort.

        What changed my mind about the whole thing was my kids. I may not feel the particulates in the air, but my kids do, especially my eldest daughter (who has early childhood asthma, in remission) - winter comes, particulates go up, they start coughing uncontrollably all day. Particulates go down, suddenly they're healthy again (+/- running nose).

        I have limited sympathy for conspiracy theories, and very little for those burning trash in their homes, but I do understand where the smog-skepticism comes from. I still remember when Krakowski Alarm Smogowy became a thing, winter 2012; back then, this felt like a huge fad pushed by young activists on the Internet.

    Funnily enough, Kraków region has the longest live expectancy in Poland (see https://stat.gov.pl/en/topics/population/life-expectancy/lif...).

    Which is interesting, as either air quality does not matter that much or those data are just bogus.

    Well, air quality matters probably, so we are left with the data. Let's check what is the origin of this information: https://www.iqair.com/poland/lesser-poland-voivodeship/krako...

    6 stations. One from "corporate contributor" named Arek (common Polish first name, short from Arkadiusz so does not look like a big corp) plus 5 other individual contributors.

    What equipment those 6 stations have? No idea. Are the instruments calibrated properly? No idea. Are they placed in the right spot, not on the balcony near the chimney? No idea. Are they placed evenly across Krakow to give reliable city-wide data? Looking on the provided locations - not really.

    Iqair seems to "crowdsource" their measurements so they get "crowdsourced" data, which can be total crap. Do they even verify those data? How? No idea.
