  • I remember them from the 90s in Europe, they just weren’t called heat domes back then. It was just a “blocking area of high pressure” or some metrologic words. These days the media want to hype everything up, so it needs a catchy name.

    Now I don’t mean global warming isn’t real. These things happen regularly now where they were a oddity in the past and things will get very bad in the next 50 years. But it did happen in the past.

    It’s more a case of the once in a thousand year storm has become a twice a year kind of thing. But hey, we millennials are used to that right? I’ve personally seen three once in a lifetime economic crashes, with plenty more on the way.



  • As someone who has worked on embedded systems for the past 30 years: It used to be a real big deal, but for the past 10-15 years it hasn’t. We now have fully fledged multi core systems running everything. Even small embedded sensors or actuation controllers are 100+ MHz microcontrollers with oodles of flash and ram.

    Now there has been an interesting turnaround with the whole chip shortage for the past years. All the young folk are at a loss, being used to just putting powerful chips all around willy-nilly. So they turn to the old folk like me to figure out designs with less chips, running busses all over and connecting dumb sensors/actuators to a central processing unit.













  • Well yes and no. The Schwarzwald area is actually not to far from where I live, I’ve been there often. It’s a huge forest, but there are a lot of towns, homes and tourist locations in there. It’s more like an area than exclusively a forest. I doubt there is any place you can walk in a straight line for more than a couple of hours before happening upon a road, home or town.

    It’s also a very popular tourist location for people near and far, so it can be quite busy there.



  • This has been looked at and methane pockets are burned sometimes. When extracting oil for example there is often a lot of methane, which is burned to turn it into co2. The problem is, we are talking about a huge area with not many people or infrastructure in them. Sometimes the methane builds up in pockets which then can be burned easily, but most of the time it’s out gassing over a big area with very little methane per square meter. Capturing that methane is not practically possible.

    Maybe some combination of sheets which are reflective to reflect sunlight instead of absorbing it and at the same time direct the methane to a place where it can be burned off. But doing this across a large area would be hard and would also have an impact on the environment, so it would be a hard calculation to find out if it’s worth it. And getting funding for something like that is pretty hard. Plus a big chance of failure, what if the sheets crack after a couple of years and get fouled up, then the methane isn’t captured, the sunlight isn’t reflected and a lot of time and energy has been lost. Plus you have a big patch of nature filled with plastics to clean up.

    Methane does naturally get destroyed due to uv radiation, so it isn’t long term like co2. But it’s way more potent in terms of greenhouse and we’ve been releasing a lot more than gets broken down. Levels of methane are at a all time high and rising. On a human timescale the methane will take a very long time to get broken down, even if we would stop releasing any right now.

    There are satellites specifically made to detect large releases of methane, to identify human sources of methane which could be captured and burned instead of being released. Especially in industrial processes this is often an option.

    Large scale meat production is also a large source of methane, which is also hard to capture. Especially when we want the cows to have somewhat of a acceptable state of living, so going outside. The only way to fix this one is for people to eat less meat, however the trend has been for more and more meat consumption instead of less.
