I have used wood stoves most of my life. If done properly, it’s a sustainable and closed loop method for heating. Occasionally there’s a push against the “unhealthy pollution” of wood stoves, with natural gas selling itself as the clean solution… So there’s that.

A geothermal or large solar system may offer clean/green heating, otherwise wood heat is one of the better natural sustainable ways to provide heat.

This isn’t really about climate change, just local effects. But yeah, wood fires are super unhealthy.
