Setup
The past two years have been the hottest ever recorded on Earth. Hundreds of gigatonnes of ice have been lost in Greenland and Antarctica and levels of trapped greenhouse gas have never been so high, with carbon dioxide readings above 410 parts per million. Those vital signs tell a story of a planet in trouble, threatening sea-level rise with disastrous implications for the health of communities worldwide. Dava Newman, a NASA leader and expert in space technology and policy, offers an orbital view of planet Earth, with all of its interconnected systems, using videos and stories to demonstrate the risks and propose solutions.
