A current worry: The only people with existing deep expertise in things like how the atmosphere/ocean/geosphere work are academics, who are ace at giving impartial evidence-based advice. But as lots of climate “solutions” companies spring up, these academics are consulting with them & in some cases leaving academia to work for them (often much better pay & working conditions) & are then limited in what they can tell the rest of us. So the public source of open unbiased expertise is at risk.
