So the only thing to do is keep emissions as low as possible. The likelihood of this extremely high-impact event happening increases with every gram of CO2 that we put into the atmosphere.

It's unlikely we will be able to achieve our emissions targets. We need a combination of CO2 scrubbing, non-intermittent renewables, and even geoengineering to restore Earth's energy budget.

Before any of that we need a heavy carbon tax. "We" being every developed country. A tall order... but absolutely vital.

I think carbon border adjustment taxes by the EU and US would probably be enough to get started.
