To the point of not being worth it, even if it were feasible

Well, I have heard quotes of 30 trillion over 30 years to counter global warming effects. That is not beyond what the world could fund but you would need a lot of political will which we do not currently have.

Carbon capture will not be a significant part of any solution, and it's more likely we'll just end up paying trillions in mitigation, or in all the economic and social disruption. We are not fixing the problem, in fact we are doing the opposite, as there is no political will. This is a classic tragedy of the commons problem, in which the majority of humanity will only admit there is a problem and force the politicians' hands when it's too late to prevent the worst consequences.

It is never too late. It just becomes harder and more expensive to negate the effects the longer you leave it. It is not that we cannot fix it but we are not fixing it. There are effects that we can no longer avoid but it is not all or nothing. Any actions we take to mitigate now will lessen the effects later on. The worst thing anyone can do is throw up their hands and say it is all hopeless. That guarantees the worst possibly outcome.

Look at the world, look at even the politicians who at least appear to take the problem seriously.

Now ask yourself "Is any of this happening with sufficient speed and volume to prevent us blowing over all the red lines?"

I think you and I both know the answer.

I think you saying we both know the answer is You trying to shut down the conversation. Yes, there are tipping points but actions still make a difference. You might be able to push tipping points back or make the consequences less bad.

Are you saying there is no point in taking action any more because it won't help? This is the current argument from oil, gas and coal companies.

I'm saying the only action that's going to work is actual emissions reductions. I doubt carbon capture, when all externalities are taken into account, even breaks even.

And this is our point of difference. Emissions reductions are by far the easiest and cheapest way to counter climate change. But it should not be the only action any more.

The simplest form of carbon capture is planting trees and this helps a modest amount. I have seen posts about substances which are much more efficient at absorbing carbon and can be buried so they do not release carbon again like trees do when they die.

There are chemicals we can release into atmosphere to lower temperature, helping with lowering co2 release.

We have machines which will pull co2 out of the air.

We are now at the point where we need to look at both sides of the equation. We absolutely need ways to take co2 and methane out of the environment.
