Geosphere-Biosphere Interactions and Climate brings together many of the world's leading environmental scientists to discuss the interaction between the geosphere/biosphere and climate. The volume arises from a working group of the prestigious Pontifical Academy of Sciences and the International Geosphere-Biosphere Programme. The state-of-the-art chapters summarize our understanding of the present climate and environment by understanding Earth's past, human influence on the climate, a description of climate and its relation to the Earth's surface, ocean, and atmosphere, and future predictions of climate variability.
