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?

  • I just don't like seeing us treat this problem with an almost sacred respect. I hardly ever hear someone come up with an idea to have our cake and eat it too, and when I do, it's just dumb or symbolic things like making diamonds or plastic out of the carbon in the air. I mean, stopping carbon emissions would be desirable, but hardly a solution at this point, not to mention that we would probably need an extremely interventionist world government/police to make it possible, which is very very undesirable. And it WILL inevitably hit very hard the world economy, which, don't delude yourselves, IS NOT a fluffy concept separated from human lives and human suffering, many human eggs would be broken into that omelette. We NEED irreverence to come up with good solutions, humans are in a big way characterized by our sense of adventure, experimentation and exploration.

  • Why would they go for the replication of catastrophic events for high risk and little benefit, when they could replicate and amplify low risk naturally occurring ones with high benefits. Just prop up giant reflective fabrics over massive farms all around the world, reflect the energy back, don’t damage the atmosphere or the water, and produce more food all year-round. I don’t want to end up having to drink recycled pee

  • climate change or anthropogenic climate change? one is real and has happened thousands of time in geologic history, and hundreds of times in human history. the other, is fake. if it was real, there is one, easy quick solution that would stop the warming in its tracks and buy us plenty of time to figure out some environmental problems. planting trees. planting a billion trees. those billion trees would use ALL the excess CO2, thereby eliminating the fake problem of greenhouse gas driven global warming.

  • 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.

  • 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.

  • 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.
