I salute your courage in writing about some positive dividends of climate change. While there is plenty of bad news, we cannot ignore the positive news as well in order to adapt as a species.

Good paper - having worked on this topic for past 2 decades - specially with reference to science diplomacy between India and Pakistan, I am heartened to see young scholars still interested in the topic despite the cynicism from the politicians. Will try to spread the word about your suggested cost savings - that may get on radar of policy makers but mediation from international community will likely be needed.
