How is it not the same people? What type of geoengineering are you referring to?
Solar geoengineering seems like the most promising. It's largely being studied by climatologists. The people who are putting carbon dioxide into the atmosphere are industrialists.
Which is being pushed by Bill Gates and co., which fuck him by the way.
So because one particular person you don't like is involved, screw the science? Let the world burn rather than have it be saved with the involvement of people you don't like? Wonderful attitude.
Bill Gates is a major philanthropist, BTW. Not sure why you pick his name out as specifically hateworthy.
Also, describing solar geoengineering as "blotting out the sun" suggests you're not really familiar with how this stuff actually works. So when you say you don't think any of the proposals will help anything that doesn't give much weight to your opinion.
