- A participant questioned the credibility of proposals claiming that “$1 B is enough to fix climate change,” noting that total climate-related damages are already reported to exceed $1 T.  
- Geoengineering options discussed included cloud whitening (marine cloud brightening) as the most popular near-term intervention, with star shades (large space-based occulters) mentioned as a preferred long-term alternative.  
- Genetically engineered algae was raised as another carbon-sequestration route, but immediately criticized with the warning that it “is going to backfire,” highlighting community skepticism toward biological open-air interventions.  
- In response to the algae critique, kanzure pointed to an open compilation of human genetic-modification ideas and protocols hosted at http://diyhpl.us/wiki/genetic-modifications/, framing germline engineering as a more controllable path than planetary-scale biology.  
- The same exchange underscored an explicit disregard for formal bans on human germline engineering, with the rhetorical question “why would you let that stop you?” capturing the channel’s prevailing anti-regulation ethos.
