Explore the concept of tipping points in climate science and their potential for positive change in this 14-minute TEDxPorto talk. Delve into recent evidence supporting the declaration of a 'climate emergency' and learn about the urgent need for emission reduction. Discover how small changes in the Earth system can lead to broader, often damaging impacts that accelerate climate change, such as rising sea levels and methane release from thawing permafrost. Gain insights into identifying and triggering positive social tipping points that could help limit global warming to well below 2ºC. Understand the importance of viewing the world as an interconnected system and how this perspective can contribute to addressing the climate crisis.
