Scientists and climatologists are saying that it would impact natural resources directly, making some parts of the world virtually uninhabitable. This, inevitably, would result in mass movement of human tide.
Norwegian minister of foreign affairs, Jonas Gahr Støre affirmed that back in 2011 at the Nansen Conference on Climate Change and Displacement:
“Human displacement due to climate change is happening now. There is no need to debate it.”
The realisation, somehow, has not hit authorities in Pakistan, who remain in a state of denial. This, despite the reality of having witnessed a movement (albeit a slow one) of people from rural to urban centres, due in part to climate-related events which have been taking place over the last several decades.
Good read on displacement of people due to environmental impacts.
