What the hellish atmosphere of Venus teaches us about Earth

The End of Planetary Atmospheres · 58:30 · Video: Gresham College · Watch at the source

In short: Explore the mechanics of a runaway greenhouse effect through the lens of Venus's transformation. This lecture examines how thermodynamic principles explain the catastrophic climate shifts that rendered Earth's twin uninhabitable.

Professor Katherine Blundell OBE investigates the dramatic atmospheric changes that occurred on Venus less than a billion years ago. By studying the processes that triggered a runaway greenhouse effect on our neighbor, the lecture considers the broader implications for the possibility of similar catastrophic climate change on Earth.

The presentation also touches upon recent scientific developments, such as measurements claiming the detection of biogenic signatures in the Venusian atmosphere.
