This maybe too political for HN. It's nice to bring attention to a change agent but the more important part is the issue: there is a climate change emergency that depends on getting CO2 to 290±10 ppm rapidly. We better mostly agree that and on taking action or we and most species are all effectively dead sometime <1000 years. So, if you had a trillion dollars (less than student debt and less than the wars in the Middle East) how would you spend it on remediation? 0. Bio carbon capture & sequestration (CCS) Some ideas: - ferrous oceanic seeding of phytoplankton - only small amounts needed (See IRONEX I) - Kelp farming + underground sequestration - there's an absolutely massive kelp forest between Mexico and Africa, and thousands of tons wash-up on Mexico's beaches daily 1. Solar radiation management (SRM) - numerous ideas: https://en.wikipedia.org/wiki/Solar_radiation_management https://en.wikipedia.org/wiki/Solar_radiation_management And please don't say planting trees because it doesn't scale well [i] and they aren't a permanent sequestration solution. More trees + increasing wildfires = more soot falling on glaciers = faster melting glaciers = more sea level rise = a really bad idea. i. https://youtu.be/Z5uuIcS4kqE https://youtu.be/Z5uuIcS4kqE
