I just recently read about iron fertilization as a potential tool to fight climate change, can't believe I'd never read about it before. Potential downsides but still very interesting, especially if economical.

I strayed far away from the research side of things back in school, but I wish we had more bold disrupters or shapers in the field. I know it's antithetical to the personality, skills, structure, and honestly the traits to succeed in the field but someone who'd be bold, sway the media, public opinion and congress with visions for deep funding and just dive in and trailblaze and get stuff done instead of so much research. I dont keep up with the field and Im sure this is extremely naive but just my thoughts.
