Abstract: Planet Earth is a complex system, where various worlds (physical, biological, human) and various scales (in time and space) interact. It has been in equilibrium for the past 10,000 years, but in the last 100 years, developed and developing countries have conducted a real-life experiment by injecting in the atmosphere increasing quantities of carbon dioxide and other greenhouse gases. How does a complex system respond to such a continuous change in internal conditions ? It is an old problem, which has been investigated by famous mathematicians, from Leonard Euler (1707-1783) to René Thom (1923-2002). In this talk, I will survey the various possibilities and apply them to climate change
