The climate has always changed. The Earth has turned into an ice ball several times, and it has also experienced periods when it was much warmer than today. But if the climate has always changed, how do we know that it is humans who are changing it today? In this episode, we will delve into the climates of the past, to understand what are the major parameters that determine the climate. Are there lessons to be learned from this long evolution of the climate, to better understand current and future global warming? To answer these questions, we welcome Arnaud Lemaître, expert in climatology and scientific mediator for more than twenty years.
