3 scientific frameworks to prevent Earth system disruptions
Sep 25, 2024 · Tipping point science is an evolving field. Another group of scientists refer to 16 climate tipping elements, a subset of the broader group of 25 above. These are only triggered by a global temperature rise (not landscape changes) and their tipping affects the global climate system through reinforcing warming.
Technology’s tipping point: It is time to earn trust in AI
