Re: Potential large-scale CO2 removal via enhanced rock weathering with croplands
#3I don't like those kind of projects because they sort of try to bank on the global warming problem with inventions and new things, except this doesn't work, because CO2 is just too hard to eliminate.
It's the penultimate problem of industrialized capitalism: "we have a problem and we need to MAKE something new to solve this". But the problem was always the excess of industry in the first place. The solution is simple: slow down consumption everywhere and optimize the use of carbon, but it's completely against the spirit of industrial capitalism. That's why global warming can only be solved with political solutions.
I believe that in the future, violence will occur to stop co2 emissions by force, while the wealthy will be able to shelter themselves away from hot places. Global warming is EXACTLY the problem of libertarian ideology. It completely dismisses the commons. Global warming is the perfect example of what happens when we accept "survival of the fittest" and social darwinism. I'm worried that rich people are okay with global warming because they are able to justify it with Malthusian arguments.

You get downvoted because you provide no arguments for why it is too hard of a problem for eliminate.
You also didn't provide any arguments as to why this specific approach won't work.
It's similar to people closing their eyes when there's fire and screaming "we'll all die". It's your choice to believe that, but don't stand in the doors trying to prevent people from searching for a survival route.

That's some moral arguments you are using here, it's all nice and well in a debate but it's not moral arguments which will help in any way the humanity to fight global warming. Yes we do need technology and we need it quickly before the problem worsen even further.
Even global agreements like the Paris one are built upon having such technology, no amount of shaming and moral argument will help in achieving anything.

I disagree. We've had all necessary technology all along. It's exactly the lack of moral responsibility that's holding us back. Fighting climate change is more akin to the civil rights movement than to the Manhattan project.

#7preliminary calculations suggest this has the potential to capture about 5% of current CO2 emissions if applied to 50% of worldwide farmland.

#880 - 180 US$ for the removal of a ton of CO2 is far more than the cost of adding a ton of CO2 to the atmosphere (in Germany, currently around 10€/ton, I believe).
In principle, removing a ton of CO2 needs to be cheaper than the cost of adding a ton of CO2.

The price for a CO2 certificate is around 25€ per ton. The biggest problem is that lots of emission sources are still excluded from the CO2 trade and that businesses receive a certain amount of CO2 certificates for free.

Your argument is a different one already, yes we're definitely not doing much against climate change, and yes some moral responsibility to fight this global issue is badly needed.
But that does not validate the pseudo-moral arguments blaming technology & industry like the one above, this is guaranteed to fail.
