Unfortunately, I don't believe voting one way or another will make much difference. One party might be slightly better than another, but ultimately none will dare to implement sufficient measures.Then you are simply giving up on the whole thing? Because there is no other way to make much difference. If the current party platforms aren't sufficient, then those who care must first work to change those too. Become party members, work to select delegates that will then change it, etc. Same as any other democracy, regardless of details (in the US "party" (coalition) platforms and choices are determined by primaries before the country decides which one will assume government).
>Climate problem will have to be solved outside of party politics. We need something akin to civil rights movement. On the global scale.
It can't emphasized enough how completely, utterly wrong this is. Solving collective action problems requires coordinated use of power, which by definition is politics. Regardless of how the politics gets changed, it still will ultimately depend on politics. It's not some dirty word or concept, it's a descriptive/truism, when you work to get groups of humans to do something you're doing politics. It is our great good fortune, built on a mountain of blood a treasure, that so many of us live in democracies where it is so easy relative to history to work for radical political change through parties and government structures.
You mention the civil rights movement, but that ONLY WORKED THROUGH POLITICS. There seems to have been a huge forgetting in modern times that protest movements and the like are only means to a political end, not constructive in and of themselves. The civil rights movement had organized leadership that used the protests to mobilize voters, to gain public interest and recognition, etc., all with the ultimate aim of changing politicians/parties and actually getting actual for real legislation passed. They worked to the extent they translated into votes and in turn into actual power.
Conversely, consider all sorts of modern disorganized protests, no matter the size. It's perfectly possible to spend enormous amounts of time, effort, and resources and accomplish absolutely nothing whatsoever. It's a very dangerous and corrosive form of virtue signaling, and can actively harm progress because it burns people's limited capital to no useful end. And that in turn helps further breed disengagement, because people feel "they did something" "yet nothing happened". But "doing something" doesn't mean it's actually useful.
