It is easier said than done. Politicians do not like to be disturbed by some pesky experts. Mentor Pilot discusses 2025 D.C mid-air collision[1], and finds the most disturbing reason for it: experts tried to escalate issues with too much traffic for years, but they were repeatedly told that it was "too political", so, in other words "just shut up and deal with the traffic, don't bother congressmen and congresswomen, they are too important to be bothered with limits of possible stemming from physics or engineering".

Politicians thought (and some think to this day) that climate warming is "too political" to listen to experts. Most of them will think that Atlantic current is too political, till it stops.

It is easy to say "convince a politician", but it is hard to do. Politicians think politics, and you have to be a genius among politicians to transform a game field, so some concerns of scientists became a political issue that is not possible to ignore. Geniuses among politicians as as rare as in any other discipline, the most of them will just play existing games, without even thinking of rewriting the rules of the game. BTW, when they try to rewrite, the boring old "play by the rules" might start to look pretty good.

Politics is the hardest unsolved problem the humanity faces. We could send humans to the Moon, or it seems increasingly likely we can create an AGI, but we can't make politicians to listen to the reason.
