I don't know what to say on the climate change issue - the way I see it it's not something any one government can handle - you've said it - just gets outsourced out of your jurisdiction.

Even with trade pressures, etc. cheap energy is going to get used to increase the living standards of developing nations.

Also all the solutions proposed towards climate change issue seem shortsighted and regressive to me - everyone keeps pretending that if we reduce CO2 the earth will somehow return to a harmonious state and we will all live happily ever after. Even if cutting CO2 in the future fast enough would reverse climate change effects (which we can't really predict) there are still marginal risk factors that could end in global catastrophes (like the previous extinction events in history) and on top of that the globalised society is introducing new problems that we've had to deal with for last 50 years at best. A deadly virus outbreak with a long enough incubation time could swarm the population considering how interconnected the world is, nuclear catastrophes have potentially global impact, etc. etc.

So the politicians are talking about climate change because it's a popular topic with the voters - meanwhile the real problem is that we are dependent on an ecosystem that's incredibly fragile and society is introducing risk variables that didn't exist before.

The world is very interconnected and optimised - but this leads to fragility. We've had situations where a natural disaster in one area (Taiwan) caused major industry problems. Not to mention potential political issues like the recent trade wars with China.

The real solution is working on reducing our dependence on the ecosystem and building more resilient systems - but this is not something an average person would find intuitive - and so it's unlikely to get political support. A perfect example of where motivated individuals can make the difference - and where something like Mars colonisation research can end up providing solutions for earth. And then again it might lead to nothing, and I could be wrong and the climate change campaigning ends up working - it's good we have multiple actors pursuing different solutions.

This is often touted as a reason why we developed countries cannot do anything to mitigate climate change risks. This is first of all false, developed countries together (USA, EU, Japan, Korea, Gulf states) still account for more than 70% of the emissions, NOT including the emissions associated with importations. The lifestyles of the richest 0.54% in the world — 42 million people — are emitting more greenhouse gas emissions than the poorest half of the global population —3.8 billion people.

It's about returning to reality. The lifestyles of most of us in developed countries should not exist.

Please come back to reality. The world spends trillions of dollars on the ISS to host 6 people. Anything remotely looking like an artificial ecosystem would be prohibitively expensive, not counting our limited resources on Earth would simply make it impossible for it to sustain life for more than a few million people. You can work hard to be part of the few richest million who would make it in this artificial biosphere, or you can change your own lifestyle and footprint, try to inspire others, and then you can realise that we can still live happily with a lower footprint.

Right now a global drought for a few years can cause global food chain disruptions and starvation - focusing on stuff like algae/bacteria protein production that can be done in controlled environments, that is space scalable (ie. vertically stackable) etc. This has the potential to solve a lot of environmentally caused problems down the line. Or developing very resilient crops with GMO.

Then stuff like building protective domes around existing cities to protect from natural disasters, quarantines, etc. Maybe start as hurricane shelters for risky areas/small places and start developing the technology.

Then there are reliable decentralised energy sources like micro nuclear reactors that can power a city block - that can be scaled up and treated like nuclear batteries with localised/limited risk factors.

I'm not talking about building some random futuristic utopia - just focusing on technology that increases the robustness of society instead of focusing on economic optimisation. There is a joke that if economists designed a human 4 people would share a single kidney instead of having redundant organs on each person. The other thing is the green regressive dogma that the only way to solve the climate change issue is removing the human influence and everything is going to be fine ignoring how volatile the earth can be on its own.

These are all things that could get a lot more attention but the only solution to climate change talked by politicians is reducing CO2.
