Gregory Barber

In this insightful conversation, science and technology journalist Gregory Barber delves into the concept of climate tipping points. He discusses how historical climate shifts, like the Sahara's transformation from grassland to desert, inform our understanding of abrupt changes. Barber explains the complexities of mathematical models, including bifurcation theory and catastrophe theory. He also emphasizes the dual nature of tipping-point narratives—both as motivators for action and sources of despair. Amid uncertainty, he advocates for responsible communication of climate data.
