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?

    • The 400 year grand solar minimum cycle has begun. The next 3 decades will see the earth cool down as the suns magnetic feild turns down. GLOBAL COOLING IS THE CLIMATE CRISES now. There is Cold induced famine every time this cycle hits. Artificial attempts to cool earth will be catastrophic

    • Chemtrails happen multiple times per week. You can visual see the planes spraying patterns and turning a blue sky completely white and covered by a chemical blanket slowing falling down into our lakes and trees and houses and we are breathing it in and eating and drinking it .. how is this okay???

  • Fun fact, of the total amount of co2 released into the atmosphere each year only 5 % is humanity induced. Soooo.....the other 95% released from natural processes is totally ok, it's that small 5% humanity is responsible for that has the doomsdayers creaming their panties. Global warming is real and yes our climate is warming which it has done many times in earth's history as evidenced in the archaeological record but to put the cause solely on the back of humanity is absurd. Question: how many of you reading this post were alive in the 1970's and remember scientific consensus back then was the earth was going into the next ice age? Thats right, global warming wasn't even on the radar so the question is how could that be? The evidence was clear, science said so. WHAT YOU SAY? scientists were wrong? Truth is global climate is so complex involving a mind boggling amount of variables that even with the most powerful super computers it's impossible to correctly make any sort of accurate prediction for tomorrow much less 50, 100, or even 200 years from now. With that said we only have this small rock to live on. We need to keep it clean, science our way out of the dirty pollution problem if not for ourselves then for our descendants. Governments are run by humans, flawed humans with sometimes nefarious ambitions. All governments use diversionary tactics to hide true motivations and the sheep follow - DON'T BE A SHEEP.

  • GENIUS IDEA!!!!: what if we used asteroid mining instead of big mines to stop air pollution. We use the gas from the rockets as geoengineering to buy us more time while we use the money we make from selling the asteroid components to buy energy efficient power sources and to stop fossil fuels from being burned. Thank me later Elon musk

  • Prove that climate change is due to human activity. The earth has gone through heating and cooling periods long before humans, with co2 levels much higher than we have today, proven by drilling into polar ice caps. Trying to change or slow the earth's natural cycle could be catastrophic, and would most likely bankrupt our society.

  • Stop tellling that "CO2 traps this radiation etc". The most of it is kept by the water vapor. At least say "greenhouse gasses trap infrared radiation". This manipulation of terms is not what I would expect from you guys. What a shame.

  • Your carpet; your phone, your food, your toilet paper all contain petroleum products. The largest contributor of green house gasses is meat production. Cows on average release 3.1 gigatonnes of co2 a year. In fact with the advent of modern catalytic converters and diesel exhaust fluid systems cars release 12 times less co2 a day than the average cow. The real solution to climate change is to eat more veggies and less meat. I’m not saying get rid of meat because I like it too. Just eat a little less of it.

  • Problem is, this particular geoengineering strategy to happen is very unlikely due to the need of a GLOBAL political agreement. Say, if the USA goes all independent and does that - there is no way that the particles stay above the geographical borders of the country - cause, well, weather doesn’t care about borders. Meaning if one country does it, every other country could be directly effected. Meaning every country on earth has a say in it and all countries sharing the some opinion on this topic is just... extremely unlikely.
