In the pilot, they depict Mojave, California as being very terraformed from a desert to a lush parkland.
However, I find this a bit antiquated... this seems to be very much rooted in an atomic age scientific idealism that thought of how we could make the world work for us and bring it to more western standards of natural beauty.
I think this is in conflict with the TNG solar punk aesthetic and the general respect for nature implied by the Prime Directive - notice how there's no desert bushes in sight as if they wiped them out. This seems to be insane damage to the ecosystem.
I wonder if they'll ever revisit Mojavo on-screen, and whether they'll retcon this so that Mojave is a gorgeous desert town where they solved the problems of drought and extreme heat plaguing the southwestern US while working in tandem with and even boosting the local wildlife, rather than just razing everything and plastering grass and non-native trees over it.
I'd bet we probably only have 3 seasons for it to happen, considering that 5 seasons has tended to be the length of most recent Trek shows (except poor old Prodigy). The only thing giving me hope is that SNW seems to be a decently successful series.
Pretty sure TNG and some of the ST movies mentioned weather controls. And there have been many mentions of terraforming entire planets.
So I doubt Mojave would get retconned.
I agree weather controls exist - in fact, they'd probably be needed to solve extreme heat and drought in the city.
However, I don't think terraforming Mojave is the same thing as terraforming a planet - most planets they colonize that aren't already suitable for human life don't have a native ecosystem to begin with. What the pilot seems to depict is the elimination of an existing ecosystem and many habitats, which I feel doesn't seem very Trek-esque. While they would modify the local environment to improve living conditions, I don't think they would be inclined to do this much environmental damage.
