I have a question; if some of the worlds trillionaires suddenly decided to dedicate massive amounts of funds to fighting climate change, would it work? Could we solve this problem simply by throwing money at it? For example, nuclear power plants generally take a lot of resources and time to build. Is there enough money in the world to throw at the problem to build 1,000 nuclear power plants in the next 5 years? Or what if solar panels and household batteries became free to everyone on the planet? Would that solve the problem? I know that changing people's minds and changing laws are hard to do, but is there enough money in the world to make it happen? Money makes laws all the time and giving people free stuff generally makes them compliant.
