    The number of times I’ve had to explain to adults that the sun is a star is way more than it should be. It never stops being so disappointing too that even the most basic shit, not this exclusively, is just something so many people don’t know, think about, have any interest in and don’t ever read more than the sparse title about that thing in the news (those titles and articles often being partly of fully false).

      This and “humans are animals”. It’s shocking the amount of times I’ve had to argue this.

      I’ve explained to many adults, many with college educations, that insects are animals. Understandable for those who don’t realize corals are animals, but they think bugs are plants or something? Smh

        I think for many people, when they say animal, they think vertebrate. When asked what insects are, they can’t answer.

    I know it is a meme, but I feel this is a little too belittling of climate change being responsible for increase in temperature. Like, I can see this unironically shared on Facebook and twitter with people being “hurrdurr, fake climate change, heat comes from sun!!!”.

      My conspiracy theorist mom shared stuff like this all the time. This will absolutely be shared among climate change deniers as they roll coal on their way to the funeral for their daughters who died in the Texas floods.

    Idk anything about stars or solar systems, but when my house gets too hot I just close the curtains and it helps everything cool down. Maybe we can close earth’s curtains and will fix it?

      This does happen and it’s an effective way to decrease the temperature:

      Might be difficult to implement at scale though.

        That’s literally a photo of it happening at the only scale that matters. The solution is that once the moon is there, we just need to stop it from moving away.

        Problem solved forever.

        A orbiting, remotely positional, moon-sized sun shade? That’s crazy enough to work I think you’ve solved the heatwave here

        Couldn’t we do this in a more localized way for large cities? Like a big ol’ shade satellite for areas being dangerously affected by heat waves? I know it’s just a bandaid but we will need these kinds of extreme weather mitigation techniques to keep us alive so we can solve climate change or die trying.

        Ps I’m not a scientist, so this is a sci-fi idea only - as in idk the maths of what this would take.

          The structure you describe is called a Soleta. If you are interested, space nerds have explored the possibilities in some detail.

        It’s not really hard to implement at all but would just trade pest for cholera. We could just burn a lot of coal again, the dustier and dirtier the better. But that’s pretty bad for air quality but it would seriously cool the planet.

            Aerosols aren’t gases in the classial sense and reflect sunlight. This works especially well high up in the atmosphere.

            https://science.nasa.gov/science-research/earth-science/climate-science/aerosols-small-particles-with-big-climate-effects/

            There are studies that collect data around volcano eruptions and coal power plants getting online and offline. Long story short: Climate is complicated; I’m not a climate scientist and not to be trusted; it would work great at cooling the planet; we definitely shouldn’t do it (yet?) because it masks the temperature problem and could lead to us not reducing CO2 because we “wouldn’t have to”, but it could be a tool if we might be on the edge of a catastrophic runaway effect that causes too much water to evaporate into the atmosphere.

            Update: Btw, you are right about dark particles low in the atmosphere, those typically warm the planet. It’s mainly sulfur dioxide aerosols byproduct that cool the planet (also mentioned in the NASA article)
