Fundamentalist Christians tend to find the notion that puny humans could influence the weather in some significant way to be a blasphemous denial that god is in control and has given over dominion of his creation to his people. If this led to a sense of responsibility and stewardship for the environment and the creatures living within it, that would be one thing. But for fundamentalists it is just cover for a sense of entitlement to pillage the environment at will. Because as you point out, god will either protect or provide for his own, or rescue them, from any consequences.
