The time is past when humankind thought it could selfishly draw on exhaustible resources. We know now the world is not a commodity, is not a source of revenue; it’s a common good, it’s our heritage. And the consequences of climate change are fully known now – we’re not talking about theories anymore, we’re talking about certainties.
Climate change, in some regions, has aggravated conflict over scarce land, and could well trigger large-scale migration in the decades ahead. And rising sea levels put at risk the very survival of all small island states. These and other implications for peace and security have implications for the United Nations itself.
