There are probably better ways to block out the sun. Glass is heavy and would cause a lot of problems. Something that floats high in the sky would be better, but it would unfortunately move with the wind and weather. If you could get something big enough to space, in a geosynchronous orbit, it just might work…
A large swarm of satellites, forming an adjustable solar shade, sitting around L1 for Earth-Sun is likely the best approach we would have. The swarm wouldn't be in a geosynchronous orbit, though, but instead a heliosynchronous one.
Wouldn’t anything sizable enough to make a noticeable difference immediately act like a solar kite and be wisked off into space, L1 or not? They’d have to all have force sources(ionic engines or something) to counteract the force. I wonder how practical something like that would even be on something of that scale. Interesting to think about.
For something that is positioned at L1 for an indefinite amount of time, with a large enough area to be effective as a solar shroud, it'll definitely have an impact.
That kind of shroud is effectively a solar sail without the ship attached.
Is this a viable solution to way to avoid the effects of climate change? It’s unrelated. The whole thing is to emit less carbon. If the dome does that, then yes.
Would it be cooler in the dome? Dude, domes are very cool. That’s why chrome-dome is such a compliment. In terms of temperature, probably not. Heat needs to dissipate, and any sealed area is going to maintain thermal momentum more than an open space. Unless you started out cold, then it would stay cold for longer than an open space.
Would there be any negative repercussions? Yes. But you’ll have to be more specific. It would be a huge undertaking that probably wouldn’t be possible, emit lots of carbon, probably be protested by a lot of people, huge waste of resources, etc etc. Not to mention this experiment has been attempted many times and never been successful.
Would clouds form inside the dome? Could it rain in the dome? If it was big enough, and therefore yes.
Would the rain be more toxic than usual because car fumes wouldn’t dilute as well? How big do you want this dome to be?? It would have to be absolutely massive to make it worth having cars inside.
Could outside lightning break the dome if it got struck? Well, it’s going to be pretty thick isn’t it, so unlikely. It would blacken and melt the glass over time. But at the scale you’re suggesting, it’s essentially a mountain that would peak above the clouds.
Would there be a single point in the dome that the sunlight would be directed to that everyone would just have to avoid, else they just burst into flame? As … fun as it would be to be smitten by the sun, I expect the glass would be so thick, it would be quite dim inside so, I don’t think so.
It wouldn’t solve everything, but at least there wouldn’t be room for chronic reification, useless charismatic narcissists, Cartesian dualism, etc to become big issues like they are in our world.
My point isn’t that autistic people have a single, utopian personality, but that we’re generally less susceptible to certain social/psychological phenomena that tend to make societies shittier.
I don’t think humans have the capacity for utopia. We can cooperate, but even if we achieve a near-optimal performant system of any kind, we never achieve stasis. We have before changed things for what can only be collectively said to be for the hell of it (when in reality it was because someone individually benefitted) and any utopia we’d achieve wouldn’t last long and then we would erroneously attribute mistake of that Utopia’s fall to its general feasibility. Plus I fail to consider a society that can’t last as one that is utopic.
So… We won’t.
But robots will. Once we’re gone and they’re still around.
And I don’t think that is a good thing for the robots either.
Conceptually I mean some structure large enough to do something with respect to a star. Yes, it is different literally, but not in the sense I was trying to refer.
I’m late to this party because I’m on the other side of the planet in a sub-tropical climate. I agree with the commenter from India and want to add:
• if you have a cotton cap / beanie / soft hat, get it out Wet it, wring it out, and put it in your freezer in roughly the right shape for your head. Use whatever is in the freezer to shape it, then let it freeze. Remove from freezer, put it in your head, and thank me for the brief but blessed relief.
• Wear a light cotton long sleeve top. Wet the sleeves and stand or sit in front of a fan or in a breezy spit in the shade. It’s like air conditioning for your skin.
• Wet your head for instant relief. Your wet hair will help keep you cool for longer.
• Plan your day around the heat. If you have to go out, do it as early in the day as you can to avoid the heat. Stay in the shade as much as possible, but somewhere with good air flow
I live in South Vietnam. I stay inside for the hours between 12 and generally 3-4. If I’m outside during those hours, I stay still as much as possible. Always have a drink: lite tea is common here. Avoid direct sun, cover exposed areas of skin when traveling. Evaporative cooling is your friend. You can keep a small spray bottle of water with you. Fans heat up a room if the room isn’t vented, so keep the fan on, but crack the door if you don’t have AC.
I’m originally from a city quite close to Canada, known for harsh winters, and now I live in a place where 40c is common. If the temperature gets too high, or you begin feeling sick/dizzy. Find a place to cool down and hydrate. Heat stroke is no joke.
For some reason, I’ve never really thought about this. I splash my face, my neck, wet my arms and legs, but I always forget the top of my head.
Maybe I unconciously assume my hair provides good shade, but it’s definitely not long and thick enough for that.
plan your day around the heat
This is probably the most important part. It’s quite easy to do that on weekends, but many people have their set in stone hours at work that just aren’t compatible with that kind of weather.
We need to figure out how employers can be more flexible with allowing their employees to work around the heat when possible. It’s normal for construction workers to start earlier and pause during the hottest hours, why not do that in the office too?
Some middle-european countries are starting to consider the siesta model of their southern neighbours, and I think that’s not a bad idea at all.
It’ll happen if Lemmy gets big enough. I only worry about search engines getting tangled in the natural duplication of Lemmy posts.
Like, if a web crawler sees a Beehaw post, and then seees Lemmy.ml’s mirrored page of that same post, could it just show up as two different results? Could it work against the SEO in that it gets marked as “duplicate” or “spam” content in some way?
If/When Lemmy and other federated services grow to the point that’s an issue in major search engines, said search engines should be smart enough to group and/or suppress mirrored results.
You can see that sort of thing in Google now for major sites like Reddit and StackOverflow, though it’s more along the lines of “the same question in a different post”.
You can also, in the interim, just pick an instance and add, site:lemm.world or whatever instead of just “lemmy”.

The ideal solution is that the page has a canonical tag, telling search engines what the main URL for the content is: ahrefs.com/blog/canonical-tags/. I don’t know if Lemmy already does this, nor do I know how well canonical tags work cross-domain as I’ve only ever used them for content on the same domain.

I would think it’s because users only interact with their own instance. They would need to post it to their instance first before it can be forwarded to the appropriate community’s instance.
Source: my dad. He was in the Air Force, and once worked in a giant aircraft hangar that was big enough to accommodate an airship. He told me that the hangar had its own “weather”, and conditions inside the hangar were announced like weather forecasts.
That was only one hangar. Even though it was uncommonly large, it wasn’t nearly as big a city block.
On an unrelated note, I wonder how long it would take the inside of the dome to get filthy from things like exhaust.
Meditation, study, gardening, self improvement are paid jobs. We’ve given freedom to those who are able to use it in a responsible manner. Hard labor is a 4 to 5 hour gig that we take turns doing, not because we are forced to, but because we understand the necessity and value of the work. Work is not seen as something we must do to have a house and food, but it is seen as participating in our society.
Compassion, tolerance, and freedom are primal virtues.
Personally I love work, I love the feeling of charity, I love learning how to better myself.
