This is actually pretty cool. The propagation of pollution and grass to trees etc. is nice. Climate points are just given on a timer right? It almost feels like you are meant to lose and the climate is doomed, which is fair enough. As I kept playing I was able to combat it though so with work it could be overcome. Nice job. There's a good chance I looked too deeply into something made for a Low Quality jam but hey, I think this little sim is pretty solid.
