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?

    Atmospheric aerosol injections have been happening since the 1990s, and it's been ramped up since the evolution of the internet and spreading of information. Just watch a "chemtrail" timelapse. Those are NOT normal skies. It is literally causing a dimming, and placing a milky HAZE over the entire sky. Those were not the BLUE skies of my childhood. There is also a reason youtube has to censor anything about chemtrails with their little attachments.... the same reason they put those attachments on anything contrary to the main stream narrative on any given topic.

    oh wooow you're soooo smart, if you give 100000 trilion meals to a single human being, can they eat all of it instantly?? no! Plants can absorb carbon dyoxide, but not on that scale, and by cutting down trees you're releasing that carbon into the atmosphere, because plants don't just magically transform carbon dyoxide into oxygen, they have carbon as a biproduct that they keep stored. More plants doesn't equal more storms, you people are the problem with this world, you are the exact example of the dunning kruger effect, you people have a 10 miunute research on google and think you've acquired all the knowledge in the universe, meanwhile there are people that dedicate thgeir entire lives to science, helping us.
