Here you can read the latest insights on how the climate is created and the mechanisms that determine it, and why the climate fluctuates between tropical hot and icy cold.These mechanisms include: -Plate tectonics that controls the import of CO2 into the atmosphere and chemical processes to remove the CO2 from the atmosphere.-New logically constructed analyses of the ice cores drilled in the Antarctica ice cap that shows the minimum reaction temperature of the CO2 removal chemical processes determining the climate during the ice ages. -The circular manner of the Antarctic ice cap melting from the bottom and its continuous replenishment by fresh snow that explained the stability of the Antarctic ice cap.This book is written in clear English so that both citizens and students can form a solid grounded opinion about the climate. For scientists, the latest insights on the climate are given here, in particular on the origin of the ice ages from an extraterrestrial to one based on chemical processes.
