The climate of 2050 depends on today’s choices. By this date, the average global temperature will have exceeded the threshold of 1.5 degrees higher than in the second half of the nineteenth century. What consequences await us? Climate models help build projections of possible future scenarios and make informed decisions. The laws that describe the climate, from mechanics to thermodynamics, have been known for centuries. But climate, like weather, is a complex system, in which variables interact with each other and influence each other.
To study climate change, science today uses increasingly powerful computers, capable of processing large quantities of data and creating increasingly realistic simulations. From the physics and mathematics of the climate, to the tools for predicting global and local impacts, this book is a guide to understanding the work of those who do research behind the graphs and acronyms that bounce around the media, including the most difficult “mission”: communicate data to political decision makers.
