Proviso of this is that, globally, politicians grow a spine, along with a sense of morality, and long term planning. It would also require them to deal with the money hoarding issues with the hyper rich.

• The first step is a massive push for renewables. They should be representing 200-500% of grid demand regularly. If nuclear can get up to speed and be part of this, great, but we can't wait on it.

• That excess power should be soaked up by large scale, portable, energy storage. Green hydrogen is the current best option, but synthetic fossil fuels could also take up the slack. Depending on the area, desalination could also be combined into this.

• We seriously decarbonise the transport networks. For vans and smaller, electric vehicles win. BYD have demonstrated that low cost electric cars are viable. For larger vehicles, where electric becomes inefficient, hydrogen is viable. This is where a lot of the excess hydrogen will be going.

• Carbon credits with teeth. Rather than relying on a planned economy mindset, we can make capitalism work for us. We need a global fixed carbon emission limit. This limit should trend towards net zero on a preset timetable. Credits are bid on, akin to stock market trades. Companies must have credits by the end of the year/period. The fine for not having credits should be a multiple of the closing credits price (10x?). The fine for falsification should be multiples of that, erring towards corporate execution levels.

This will force easy savings out of the market quickly. It will then force compulsory emitters to factor in Carbon costs.

• Combined with the carbon credits will be negative credits. If a group takes a ton of CO² out of the air, long term, they gain a new credit. They can sell this to emitters. This will provide the CO² emissions industry requires, while meeting net zero.

An example of this might be large scale bio capture on the open ocean. Grow seaweed etc on pontoons, and turn it into a solid. This can then be locked up (old coal mines?) taking carbon out permanently.

• Geo engineering. There are multiple methods of reducing incident sunlight on the earth. Everything from powders in the upper atmosphere, to mylar solar shades at the Lagrange point. They will be short term fixes, but will buy us time.

None of these require massive reductions in quality of life. They do require changes in how we do things. It's also worth noting that I've not covered the numerous problems to be solved e.g. power grid upgrades to account for renewables. None of these should be insurmountable however, just engineering, or political/policing challenges.

An no, I've no fucking idea how to get politicians to grow a spine and do what's required for our long term comfort/survival. Fixing the planet? That's just a (really big) engineering problem. Fixing human nature? ...Fuck knows.
