Green swimming pools and water features.
Those are the only “climate change” situations I can think of. Haven’t heard anything about more rain than normal in Nevada.
Those things can develope in wet grass. Doesn’t take long.
The mosquitoes were so bad here this Summer that I had to order netting for my bed and practically fumigate as when I lived in Africa. I figured it was from the amount of untended pools we have here from uninhabited homes. My gardener agreed with me. I know several years ago at an HOA meeting they were trying to do something about the green pools of absent homeowners. Being in real estate, with the economy, I suspect the problem has gotten much worse, especially when the banks start looking for realtors to handle their foreclosures. I made a mosquito dunk and it seems to have helped significantly.
