Senior officials from a number of developing countries have called for greater international cooperation to help the world’s poor and vulnerable States respond to climate change – the central focus of this year’s annual high-level debate of the General Assembly. Marco Hausiku, the Foreign Minister of Namibia, said climate change is a global issue with serious implications for economic growth, sustainable development and the achievement of the Millennium Development Goals (MDGs), a set of global anti-poverty targets toward the year 2015.
