In climate science, 2°C has become a magic number. It is the threshold below which many climate researchers believe global temperature rise has to be kept to avert catastrophic consequences. The 2°C limit is the backbone of the 2015 Paris Climate Agreement and requires massive cuts in carbon dioxide emissions. Abby Rabinowitz and Amanda Simson take a close look at the UN’s computer-model-generated climate scenarios and the technology that might help the world stay within the 2°C limit. getAbstract recommends this article to scientists and entrepreneurs concerned with the long-term impact of climate change.
In this summary, you will learn
- Why the UN’s 2°C climate change goal is currently unrealistic,
- How carbon is removed from the atmosphere, and
- What kind of technologies could save the world from catastrophic temperature rise.
