Climate change is destroying our path to sustainability. Ours is a world of looming challenges and increasingly limited resources. Sustainable development offers the best chance to adjust our course.

One of my earliest memories is walking up a muddy road into the mountains. It was raining. Behind me, my village was burning. When there was school, it was under a tree. Then the United Nations came. They fed me, my family, my community.

The unity in diversity of the United States is one of the country's greatest strengths.

Now, more than ever, we need to connect the dots between climate, poverty, energy, food and water. These issues cannot be addressed in isolation.

Given the nature and magnitude of the challenge, national action alone is insufficient. No nation can address this challenge on its own. No region can insulate itself from these climate changes. That is why we need to confront climate change within a global framework, one that guarantees the highest level of international cooperation.

The world is over-armed and peace is under-funded.

Nothing is more shameful than attacking sleeping children.
