Word Request: synonym for "conversion" without the religious connotations?

Suppose I had someone who didn't believe climate change was real, or a problem worth working on. And then they become convinced that it is a real and critically important problem, and even devote a lot of their energy to mitigating that problem. It seems natural to me to say that they've been "converted", since not only have they changed their beliefs, but they have done so in fundamental way which has lead to meaningful changes in the way they live their day-to-day life.

But I don't like the connotation that this is a religious issue, as opposed to a rational, scientific issue. I would like to be able to say things like "I'm trying to convert people to being climate activists". Is there an alternative?

A few alternatives I sort of like (but I'd still like something better):

• recruit
• mobilize
• win over

Solution 1:

Convert is fine. But if you want something else, try “reformed” though its not less religious. Just don’t let religion stymie your language. Its a losing battle man.

Solution 2:

Honestly, I think that the most suitable word here is "convince".

According to Lexico, the definition is as follows:

convince transitive verb

1 Cause (someone) to believe firmly in the truth of something.

So, you would be able to say, "I'm trying to convince people to become climate activists".
