I used to argue about climate change a lot with people, but I finally came to the conclusion that it doesn't actually matter if you and I agree on human-caused climate change or not - why? Because we all want clean air and water and soils, right? So if you're fighting against pollution just because of health and I'm fighting because of both health and climate change, we're still both fighting for the same thing (I also have a spiritual motivation and it sounds like you do, too).
The individualist narrative (as in, "do your part to stop climate change by altering your lifestyle") has been proven to have actually come from the oil companies, the carbon footprint of individuals came from them, just like anti-litter campaigns such as Keep America Beautiful was a point-the-finger-at-individuals-for-littering move created by the companies making the disposable packaging in place of what used to be bottle return systems. Recycling plastic campaigns came from plastic manufacturers so that everyone would believe the problem was solved and you could just recycle; except of course almost no plastic actually GETS recycled and it's all greenwashing.
So while yes, I try and live as "green" a life as I can, I know damn well that it isn't me and you doing most of the damage, and it serves those that DO the majority of the damage for us to focus on just our own actions. If we're busy arguing about how gas guzzling someone's car is and not the literal tons of waste coming out of the factory or the oil spills gushing into the ocean that is on fire, then they get to keep polluting.
