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?

    Yeah, no. Bad idea. A huge overreaction to a problem we cant reasonably get rid of. The world isnt ending in no where near a few decades unless we break out in nuclear war. Geothermal and renewable energy is just as costly on the environment as fossil fuels are. None of these are bio degradable or friendly on the environment to make. These renewable power sources make up a tiny fraction of power in this world and is only able to be sustained because of fossil fuels. We have no reasonable alternatives to these harmful fuels. Renewable energy is just way to unreliable and expensive on us and the environment. We have no technology to replace fossil fuels. Nuclear is too expensive to build everywhere, and can only be done through government. Hydroelectricity from dams can only be made if there's a river to stick it in. Both these still hurt the environment.

    Co2 needs to be halved by 2030 just to start, as well as rapid biodiversity increase, as well as preventing the savannahisation of the amazon (it's on the brink). This wont happen. So then the irreversible tipping points kick in. 9 yrs then its too late. I dont see sufficient change happening. Most rich governments are still in denial, and they wont fund changes in poor countries either. By 2050 we'll look back and wonder why we didnt take action. Billions of refugees, mass starvation, water shortages etc. etc. and too late to do anything about it, amazon gone, ice caps gone, permafrost releasing methane and pandemics etc.

    Holy crap! This is a bad idea. The environment is the most complex system on the planet. Who would we trust to tinker with it? "Experts" like Dr. Fauci? This is the same, old, Malthusian bull***t in new wine skins. The truth is scientists can't accurately model the environment. It's too complex. If the earth is warming, it's because of the sun. We are far, FAR too small to have a significant impact on it!

Then the earth takes its attractions and becomes glamorous, and its inhabitants think that they have mastered it. Then Our judgment comes by night or by day, so We make it a wasteland as if it never prospered yesterday! It is such that We clarify the signs to a people who think.

    Clearly that sulphor aerosol is not a good idea lol. The leaders would most definitely use it as an excuse and the best idea I got when watching this is why not develop a technology that converts CO2 into Oxygen or water or something useful and the byproducts can be captured and disposed instantly to prevent any other side-effects of using such tech in large scale. And I mean arent they already probably developing such tech(in R&D stage or smthn) for Astronomical Missions to Mars and beyond? All we'd need is their success and then rapid application globally and voila. Bye bye world with Climate Change issues! Ur free to use my idea humanity, just credit me as the mysterious starry that commented on a Kurzgesagt video in YT and saved the world. xd Also u can tip me and extend my survival beyond the next month or so lol.
