TED’s Countdown Summit, the invite-only gathering in Detroit, Michigan, on July 11-14th, welcomed the world’s top leaders in technology, science, business, government, philanthropy, and faith to explore solutions to the growing problem of climate change. As part of their mission, the TED events gather “people from every discipline and culture who seek a deeper understanding of the world and connection with others, and we invite everyone to engage with ideas and activate them in your community.”
