It's an INSANELY DANGEROUS thing to try with a high risk of massive unforeseen consequences and side effects.

The maximum probability is that we are going to do it anyway. It is becoming inevitable.

The lead time is low. The technology is extant. It's physically doable. Most importantly, we know it works.

When temperatures start spiking upwards and there is mass realization of how severe the crisis has become. Elites will have to respond, they will have to "do something".

Politically they will have no choice but to try this.
