Technology can change things but people that profit today from something will oppose a change.

Case in point: switching from oil to renewables - which can lower dependency to external actors a lot as solar panels and windmills have life span of years, so even if the producers suddenly refuses to sell more, one has some time to find an alternative - was done slower than it could have because of "discussions".

Since 20 years I almost feel the discussion "climate change or not" is fueled by people that want dependency on oil, such that we don't talk about the issue of a couple of big producer points of failure (USA, Russia, Gulf countries). Not sure if oil companies are smart enough to finance green groups (to which I agree generally but is besides the point), such that the public discourse stays in a conflict area (climate) rather than a simple one (independence), but if they are that would be meta-evil.
