The reality and the narrative of the climate crisis are increasingly shaping our lives.

This book explores the most complex crisis of our times using simple mental models.

Starting with the greenhouse effect -- mandatory for books about climate change -- the book covers second order effects, tipping points, the tragedy of the commons, peer effects, emergence and many other mental models.

Mental models help to cut through the noise of the climate crisis and identify underlying patterns.

Mental models won't make you an expert on the climate crisis, but I hope that they will become useful tools to understand and navigate the unknown as the crisis unfolds.

This book also tells the tale of Epnox, explorer of civilizations in crisis.
