        Lol people like you that believe humanity will always overcome make me laugh. Talk to any environmental scientist and they will tell you we’re fucked. There’s no secret technology coming to save us.

            But the earth has seen higher levels of carbon already. It has seen higher temperatures and lower temperatures. And we humans inhabit many climate zones already.

            This is like the “They can just sell their house and move” thing Ben Shapiro said about what people who live on climate change affected coasts will do. Who will they sell their house to, Ben??

            Humans can inhabit many climate zones, but several of them will become uninhabitable. The ones that contain the most people. And those people have to go somewhere. And all of the food that used to be produced in that place is gone. All of the ecosystems in those areas die, etc. etc.

            This is the “war and famine” part of climate change that people don’t often talk about. Most of the death and chaos isn’t going to be from people literally immediately burning up to death, it’s from the secondary effects of rising temperatures, drought, killing entire ecosystems, and forcing billions of people to leave their homes or die. And the migrant crises that come with all of that. If you thought Syria was bad…

            And you’re right, the earth has seen higher levels of carbon. The earth itself will probably be OK.

        The ‘future’ is not inevitable. There have been countless collapses in history. Our technology doesn’t make us immune. The people of the major Bronze Age powers probably thought the same.

        Also we do not have the means for weather engineering. If you’re talking about SRM, we have no idea what its consequences will be or how to do it effectively. It’s all theoretical. No aircraft we currently have can do this stuff. Sure, we could design it and build one, but then you need global governance to actually implement it properly. Not to mention the risk of ‘termination shock’ and countless others.

        Have a look at the scientific literature: https://www.semanticscholar.org/paper/Stratospheric-aerosol-injection-tactics-and-costs-Smith-Wagner/e4e5a78335eda8c16557b32af915798b06091362#cited-papers

        Would you seriously risk the future of life on Earth on something this experimental?

        I fear this arrogance will kill a lot of people and cause a lot of suffering.

            Firstly, that isn’t ‘already done’. It’s a PR statement from the Chinese government about plans. The stuff they have already done, like reducing hail etc., is nowhere near the same level to what is needed to stop climate change.

            Secondly,

            Radical solutions such as seeding the atmosphere with reflective particles could theoretically help reduce temperatures, but could also have major unforeseen consequences, and many experts fear what could happen were a country to experiment with such techniques.

            This is from your source ^

            So is this:

            In a paper last year, researchers at National Taiwan University said that the “lack of proper coordination of weather modification activity (could) lead to charges of ‘rain stealing’ between neighboring regions,” both within China and with other countries. They also pointed to the lack of a “system of checks and balances to facilitate the implementation of potentially controversial projects.”

            Think of the geopolitical mess this kind of thing would create. If it works that is.

                Sure, I like the idea of space megaprojects. I doubt sunsails in orbit would be profitable though. How would you monetise it? Put massive ads on them? Charge everyone a subscription fee?

                Now, governments could probably do something like that, and I wouldn’t be against it if safety and unintended consequences were taken into account somehow.

                Also, I thought you believed space exploration tech was useless.

                I agree there are many solutions. I don’t think markets and capital are going to make them happen.

                We can probably buy time with tech solutions. Long-term solutions will have to involve major fundamental sociopolitical change.
