The World's Greatest Environmental Challenge

The most colossal environmental disturbance in human history is under way. Ever-rising levels of the potent greenhouse gas carbon dioxide (CO2) are altering the cycles of matter and life and interfering with the Earth's natural cooling process. Melting Arctic ice and mountain glaciers are just the first relatively mild symptoms of what will result from this disruption of the planetary energy balance. In CO2 Rising, scientist Tyler Volk explains the process at the heart of global warming and climate change: the global carbon cycle.

Toward a Physiology of Earth

The concept of Gaia resonates with a wide range of people— from nature lovers, theologians, and philosophers to environmental and earth systems scientists. The term, which scientist James Lovelock, originator of the Gaia hyposthesis, borrowed from Greek mythology, refers to the interacting system of life, soil, atmosphere, and ocean. Like the interiors of organisms, Gaia contains complex cycles and material transformations driven by biological energy. Gaia's inclusion of life means that from some perspectives it resembles life. But Gaia also differs from organisms in significant ways.
