What can the climate on Venus tell us about Earth? On this episode, Neil deGrasse Tyson and comic co-host Chuck Nice answer questions about climate modeling, the state of climate change, and future predictions with climate scientist, Kate Marvel. What if the Earth had no Rocky Mountains? Learn about climate modeling and what it’s like to play Sims with physics on a supercomputer. If Thanos’s plan worked, would that put a stop to climate change? Find out why the human population isn’t the problem and when we will see the benefits of various green initiatives. What if humans were half the size we are? What is the difference between weather and climate? What changes that we’ve caused to our climate are actually reversible? How many more droughts will we be seeing and where? Learn about places where rainfall will increase and where it will decrease. Are models good enough to replace empirical experimentation? We discuss climate research on the moon, Mars, and Venus. What are the top five most important climate solutions? Discover creating worlds in a supercomputer, Newton’s laws of motion, and climate modeling organizations around the world. We take a look at systemic changes that are helping the cause and how to get people in power to care about climate change. How can we communicate urgency without people giving up hope?
