A lot of otherwise-reasonable climate researchers seem to have an unduly negative view of potential direct interventions in the climate, and for good reason. Scientists know that theory and practice often are very different. You can't 'experiment' with global scale geo-engineering.

To put it in HN terms: you're deploying untested code for a global scale life support system written by a first-project-junior in an experimental new technology stack directly to production without having a test or staging environment, and there are no backups.

Obviously! But the theory of Anthropogenic Catastrophic Global Climate Change is different. This one is beyond reproach and matches practice perfectly.
