Taking it fucking seriously as a nation and implementing any of the possible externality capture models in earnest. That means a rapidly scaling(5 year) decline in oil subsidizes to zero, a rapidly scaling ban on fossil fuel power (10 year) and a rapidly scaling (10 years) deployment of a carbon tax credit system, and at least a 100x government research grants on carbon capture technology. All of the above, in sufficient numbers, would achieve surefire results without taking absurd risks and massive gambles. All of it, and many other things, have been researched and talked about to death for years, rigor and scrutiny that geo engineering has not.

They haven’t been implemented because vested interests have billions of dollars to keep those changes from happening, and the public has not put their ballots behind it, leading to very unserious short term thinkers in positions of power. Change that, and we could easily afford to do this, we have the money and lack the willpower.

Frankly, I would've agreed with your opinion... Maybe 20-30 years ago?

I think it's clear that nothing will be done - and initiatives that end at a national level are meaningless from a climate perspective.

You should definitely still try to get your locality to do them, because they increase your quality of life by reducing local pollution... It climate change relevant? No.

15-20 years ago I would've said we need a more global approach to this, actual binding agreements - enforced globally through a body that has the ability to force the nations to actually adhere to them.

But now, in the last 5-10 years I've most certainly lost any kind of hope that such a initiate would not end being leveraged by someone like trump to sabotage others.

Honestly, I currently consider any climate change oriented political decisions to be irrelevant at best. It's gonna happen, so if you do something - do it for your local environment. If you try to signal with global warming I am forced to see you as at best a hopelessly naive person, as I was 30 years ago

I think we're well beyond proving humanity can't shed greed to the point it hinders our ability to survive long term.
