"you can also do something to reduce the atmospheric CO2"

Would you mind sharing this 'something' that magically makes CO2 disappear? Because unless you're suggesting to stop using cars and electricity, there'd be a lot of people interested in that method to stop climate change.

"Take a small country like Switzerland. We cannot afford to lose any land."

Meaning since Switzerland can't afford to lose land, other countries have to. But then why not just built nuclear power plants outside of Switzerland and import power instead?

"I don't care about the probability, I care about the possibility."

No, you always care about the probability. There is a possibility that tomorrow a big asteroid crashes into Earth and extinguishes all humans. But the possibility alone doesn't justify the trillions that would be required to mitigate that risk.

You can use excess power from nuke plants at night to power carbon scrubbers and store that CO2 in underground caverns or even convert it into fuel.
