We know that temperatures on Earth have fluctuated dramatically in the past, but we also know that by burning fossil fuels we are causing temperatures to rise faster than ever. In this episode of Crash Course Climate and Energy, we’ll introduce some core concepts that will help us throughout the series, like the difference between climate and weather, and take a look back through the Earth’s history at other periods of significant climate change.

Our home is burning. Rapid climate change is destabilizing our world. It seems our emissions will not fall quickly enough to avoid runaway warming and we may soon hit tipping points that will lead to the collapse of ecosystems and our civilization. While scientists, activists and much of the younger generation urge action, it appears most politicians are not committed to do anything meaningful while the fossil fuel industry still works actively against change. It seems humanity can’t overcome its greed and obsession with short term profit and personal gain to save itself. And so for many the future looks grim and hopeless. Young people feel particularly anxious and depressed. Instead of looking ahead to a lifetime of opportunity they wonder if they will even have a future or if they should bring kids into this world. It’s an age of doom and hopelessness and giving up seems the only sensible thing to do. But that’s not true. You are not doomed. Humanity is not doomed.

Finally, some good news about the environment. Subscribe and turn on notifications 🔔 so you don't miss any videos: http://goo.gl/0bsAjO In the ’80s, scientists discovered there was a hole in the ozone over the South Pole. A significant layer of gas that deflects much of the sun’s radiation was disappearing much faster than anyone expected. Projections suggested it would collapse by 2050, increasing skin cancer rates, harming crops, and destroying the marine food chain. The situation was dire. But today, we are on the path to recovery. Dr. Susan Solomon, among other scientists, contributed key findings to understand what was depleting the ozone layer and how to address it. In this video she takes us back to her expedition to Antarctica, breaks down how we managed to fix this huge problem, and looks at our next big environmental challenge — climate change — with the unbridled optimism that drove her to fix the ozone hole.
