I came to climate change not as a scientist or an environmental lawyer, and I wasn't really impressed by the images of polar bears or melting glaciers. It was because of the impact on people, and the impact on their rights -- their rights to food and safe water, health, education and shelter. And I say this with humility, because I came late to the issue of climate change. When I served as UN High Commissioner for Human Rights from 1997 to 2002, climate change wasn't at the front of my mind. I don't remember making a single speech on climate change. I knew that there was another part of the United Nations -- the UN Convention on Climate Change -- that was dealing with the issue of climate change. It was later when I started to work in African countries on issues of development and human rights. And I kept hearing this pervasive sentence: "Oh, but things are so much worse now, things are so much worse." And then I explored what was behind that; it was about changes in the climate -- climate shocks, changes in the weather.
