Even if you could personally witness trends over a longer amount of time, it is still easy to attribute that to something else. The process from eg. driving a car via a gas you cannot see to solar radiation being captured warming up the planet and all the effects from that is relatively abstract, I guess. It's still easy to not see the links between these things, if you do not want to see them.

But regardless, people who can see the curvature of the earth (and could perform other experiments) can still manage to be flat-earthers, so hard-core idiots cannot be convinced of whatever obvious things they choose to not believe in.

Governments will have to set the right incentives for these people to still do the right thing for society in general. Eg. a carbon tax. It's much easier to know which item is cheaper and then choose that.
