By the end of the 21st century, humanity is becoming desperate. Decades of heatwaves and droughts have led to unusually poor harvests, while the warming oceans yield fewer fish each year. In the tropical zones, millions suffer from famine and resource wars have made millions more flee to the north. As things quickly get worse, in an act of desperation, the world's governments decide to enact an emergency plan...
It is far from certain that a grim scenario like this will play out. But the failure of world leaders to effectively address climate change, makes it far from impossible.
So in the near future it might become necessary to try something radical to slow down rapid climate change: Geoengineering. Interventions so massive in scale that they might undo centuries of human behavior. Or make everything much worse.
What is geoengineering, is it really an option and what if it goes wrong?

  • We do not have to worry about these climatic changes. More than likely a large volcano will inject the dust required to chill the climate. There is the possibility it will chill the globe a bit too much and we will be selling snow shovels in Arabia. Maybe we just accept the heating and work on ways to mitigate the adverse effects.

  • Windmills and solar panels aren't gonna be all that great and that may be why switching away is so hard Especially if we're trying to _block_ the sun, the effort into getting any solar energy would get much higher If you want an alternate source of energy that is both relatively eco-friendly and is incredibly effective I would advise nuclear energy, we already have weapons made of nuclear materials And once we start getting into fusion reactors and thorium all our power problems will be but a fever dream And there will be no more giant fields of windmills and solar panels taking up the land that could've been used for farming or left to the wildlife (thus more eco-friendly) When all you need is one comparatively small facility

    Talha KoçTalha Koç2 dögum síðan
    • Nuclear is the best by far in all categories. The waste produced by modern reactors is extremely small in quantity; better than burying millions of turbnine blades and old silicon panels in teh desert. The death toll is far less: especially less than wind power, which kills more utitlity workers per watt than any other.. oh and it works when the sun goes down and the wind is low.

      Prime RoyalPrime Royal14 klukkustundum síðan
    • @Prime Royal Wrong, liquid nitrogen is a lot harder to produce, CO2 becomes a liquid at a very cold temperature and a lot can be obtained into blocks which last for 35 minutes at room temp, whereas liquid nitrogen quickly evaporates and is much harder to condense.

      If Only We couldIf Only We could14 klukkustundum síðan
    • @If Only We could Dry ice making process is energy-intensive. Besides, liwuid nitrogen is much cheaper and efficient than dry ice. Also because of the liquid state, liquid nitrogen can be used in ALL machines, as opposed to solid dry ice.

  • Imagine, all of humanity, trapped in a spaceship. The engineers and scientists have discovered something drastic: this spaceship is on a direct collision course with a massive planet, albeit in the far future. However, turning the ship is hard: it needs a lot of pilots and captains to do it, and it might take years. But there is time, so they have two options: Either they try to steer the spaceship away from the planet, which will take a lot of effort and money, and will require everyone on the ship to push on one side, but the scientists are confident this will work with less drastic measures and consequences than the second option: blowing up the planet. Sure, everyone might continue their usual life, but the risks are immense: the planet may not blow up, the explosion may even fling a part of it directly to the spaceship, damaging it even further. But it might work. Despite this, a lot of captains and pilots deny the planet approaches. Now, which solution will you choose? Reduce the CO2 in our lives to steer away from danger, or blow up the planet?
