Several possible “future scenarios” and implementation pathways lead to significant UN and global governance reform. The “rational trajectory” would involve international governments, responding to well-mapped and emerging crises, convening a UN Charter review conference to adopt changes such as those proposed in this book. In a “business as usual” trajectory, governments would do “too little too late,” with insufficient leadership for the reforms necessary to navigate current and emerging crises. Such a “drift” scenario is a recipe for inevitable disaster, with uncertain economic, ecological and human costs. Rebuilding after major global disaster(s) is a third scenario, if, for example, the world stumbles into war, or the Earth shifts into a worst-case “hothouse” scenario due to unchecked climate change. Finally, this chapter explores some immediate steps the international community could take, including; reopening a serious and wide-ranging debate on the need for revision of the UN Charter, with a coalition of like-minded governments not allowing the threat of the use of the veto to stymie debate and action; and effecting priority reforms as soon as possible, including, for example, the establishment of a World Parliamentary Assembly, and enhanced international action to address effectively climate change.
