How 2023 Broke Our Climate Models with Neil deGrasse Tyson & Gavin Schmidt
StarTalk・2 minutes read
Climate update reveals 2023 as the hottest year globally, with a focus on climate models, historical data, and the impact of phenomena like El Nino and La Nina. Efforts to reduce pollution inadvertently contribute to warming, with geoengineering solutions posing long-term risks, emphasizing the importance of making better decisions to combat global warming.
Insights
- Gavin Schmidt emphasizes the critical role of climate models in forecasting future trends, highlighting their significance in understanding and addressing global temperature changes.
- Efforts to combat global warming must consider the complexities of the CO2 echo system, where only half of emitted CO2 is immediately sequestered, necessitating a comprehensive approach to remove carbon dioxide from both the atmosphere and the ocean for effective mitigation strategies.

"Global warming impacts and CO2 sequestration"
- Global warming impacts could lead to turkeys basting in their own juices, apples baking on trees, and the ability to grill on George Foreman; however, making better decisions is crucial to slow down or stop these effects.
- When reducing CO2 emissions, half of the ton put into the atmosphere is sequestered immediately, with the other half remaining in the atmosphere and ocean; removing a ton requires taking out half from the atmosphere and half from the ocean, creating a CO2 echo system to consider.
