The Earth is changing at a faster pace than at any point in the history of human civilization. Industrialization and increased carbon emissions have caused the global temperature to rise by over a degree Celsius since the turn of the last century. This seemingly small increase has had a massive impact. Melting ice sheets are causing sea levels to rise. The oceans are warming due to increased greenhouse gases in the atmosphere. Extreme weather events are becoming more and more frequent. Species are dying at record rates. This may sound dire -- and the calls for greater immediate action are growing louder. But there's cause for hope. In part one of our two-part series, Major speaks with climate experts, policymakers, and advocates who see the climate crisis as a unique opportunity for equality and a greener and more prosperous future.
