From what? Global warming? No, it won't.
If somebody creates commercially viable fusion today, it will still take some 3 to 5 decades until it is common enough to impact our energy generation. And if it is based on breeding Tritium, those 3 to 5 decades are dictated by physics. (But just the ramp-up on constructing those power plants is enough of an issue, no fundamental physics needed.)
