The podcast episode titled StarTalk Live: Climate Science, with Neil deGrasse Tyson & Special Guests discusses the human-caused climate crisis and the importance of taking action. The guests emphasize the need for system-wide change and pressure on the 90 companies responsible for producing two-thirds of heat-trapping gas emissions. They also discuss the sources and impact of greenhouse gases on the planet, including laughing gas and methane. The podcast also touches on the importance of teaching climate change in schools and providing students with tools to examine data and ask good questions. Additionally, the hosts discuss a hypothetical scenario where a child born and raised on Mars visits Earth and whether they would be considered human or an alien.
