I was wondering if you could let me know which one of the following sentences is the natural way to say it:
- This city's weather is so polluted. (To my non-native ear, it sounds to be the most correct one)
- This city's air is so polluted. (I don't know if "air" works in this sense)
- This city's is so polluted. (I think witout mentioning "weather" it would be ambiguous)
- The weather in this city is so polluted. (to me it sounds like the second version of the sentence #1)
