Understanding Global Carbon Emissions and Climate Change

The video discusses the projected growth of the world's population and the increase in carbon dioxide emissions, highlighting the findings of the Global Carbon Budget. It explains the potential climate change tipping point if emissions continue at the current rate, and outlines two main strategies to mitigate this: leaving fossil fuels untapped and developing carbon removal techniques. The video concludes with a call to action for viewers to support SciShow and contribute to solutions.
