Third World countries (they call them Developing Nations now) were holding out for a 1.5 degree increase, mainly because their island and low-laying elevation citizens will be first to drown when the seas continue rising. And these Developing Nations are also the ones who don't have the cash to fund the infrastructure projects that we Industrialised Countries will surely initiate in order to prevent our luxury condos from washing away and our children from choking on pollution.
