Ever since the April patch, Cyberpunk 2077 has become a much wetter place thanks to the recently implemented weather system. A lot of that weather was rain, likely to make the game look pretty and play into its Cyberpunk roots--Blade Runner was a very wet movie, after all.
However, Night City isn't in a place that's supposed to be getting wetter fifty years in the future. According to climatologists, California will be a much drier place by the year 2077, and that means there won't be as much rain happening.
And if industrial trends remain as they do now, Night City can expect pollution and toxic rain to remain a huge problem.
To make the world of Cyberpunk 2077 better reflect the realities of climate change, Walrus420 came up with the California Climate 2077 mod. "Using a combo of extremely rough math and statistics on San Francisco climate," wrote Walrus420, "I've made what I think should be realistic changes to the weather probabilities."
I'm no climatologist so I can't attest to how realistic the mod's parameters are, but I can tell you that this mod makes Night City a cloudier and more toxic place to be. After installing the mod, almost a third of your days in Night City will be foggy, while 40% of them will feature some sort of pollution. Only 15% of your days will be bright and sunny, while 22% of days will feature rain.
The vast majority of the weather will be cloudy, foggy, or heavily polluted, with toxic rain being far more common than regular old rain.
This mod serves as a stark reminder that climate change exists and will dramatically alter our world in just fifty years' time. Even with the recently-ended COP26 deal, nations have basically accepted the fact that the Earth will warm 1.5 degrees no matter what we do, and most of what the meeting's political wrangling was just to prevent the warming of catastrophic amounts. Even so, National Geographic expects places like Hanoi and New Delhi to become hotter than anywhere else on the planet--perhaps even to the point of being unlivable.
