What? When did I say there weren't? Yes there are many fusion projects. They may produce power in 20 years, maybe 50, either way it needs to be pursued.

And who said anything about waiting? You are aware that humanity as a species can tackle multiple problems at the same time, yes? Fusion scientists don't work on Co2, they studied fusion, not greenhouse gases. Other people who got degrees relevant to climate change are working on that seperately.

I'm not sure what you're trying to say...that fusion physicists should go back to college and get different degrees?
