My argument to this would be that changing our world because of a faulty model system would be disastrous. Because of the advancements of the last two centuries more people have had food and water and basic necessities being met then at any time in history (and yet we still have billions suffering). Worsening their lives over something that might not happen is not a good way to run the world. The models being accurate is important so that if we do implement policy that end up worsening people’s lives we have proof that it is worth it.
