Use volcanic ash to reverse global warming (lemmy.zip)

While I was in the shower, I thought of a brilliant idea! Let’s trigger several smaller volcanic eruptions that release a semi-controlled amount of volcanic ash into other atmosphere. That will cool down the atmosphere, which should buy us some time to fix our carbon emissions.

Then I realized, that doing so would block visible light. Plants need the light to grow, and we need the plants to breathe and eat. Obviously, this is not going to be a long term solution. Oh, and how do you even make sure the volcanic eruption doesn’t spiral out of control and suddenly spew out 50 times the ash we were aiming for. Oh, and volcanoes also spew CO2 and even nastier gases, so… It sounded so good while I was still in the shower. The more I think about it, the worse it gets.

Ideally, it would allow plants to get the visible light, but block much of the heat. I don’t know which material would do the trick though. Maybe some sort of glass could work as a band pass filter.

A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The most popular seem to be lighthearted clever little truths, hidden in daily life.

Here are some examples to inspire your own showerthoughts:

Rules

  1. All posts must be showerthoughts
  2. The entire showerthought must be in the title
  3. No politics
    • If your topic is in a grey area, please phrase it to emphasize the fascinating aspects, not the dramatic aspects. You can do this by avoiding overly politicized terms such as "capitalism" and "communism". If you must make comparisons, you can say something is different without saying something is better/worse.
    • A good place for politics is c/politicaldiscussion
  4. Posts must be original/unique
  5. Adhere to Lemmy's Code of Conduct and the TOS

If you made it this far, showerthoughts is accepting new mods. This community is generally tame so its not a lot of work, but having a few more mods would help reports get addressed a little sooner.

Whats it like to be a mod? Reports just show up as messages in your Lemmy inbox, and if a different mod has already addressed the report, the message goes away and you never worry about it.
