There's no short-term solution effective enough to make much difference, that doesn't reduce the standard of living in rich countries, and/or cap the standard of living in developing countries. It's not happening. Rich countries aren't gonna say "OK, everyone, you get a lot less stuff and can't travel as much now" and developing countries aren't going to accept that they can't aspire to a "Western" quality of life. Hell, an abrupt decline in standard of living is one of the surest ways to get political unrest, violence, and revolutions, even when the reduction is from "very, very high" to "very high" (and even "very high" would probably still be too high, in this scenario).
