International Geosphere-Biosphere Programme

"[1] The International Council of Scientific Unions, a coordinating body of national science organizations, launched IGBP.[2] IGBP aimed to describe and understand how the physical, chemical and biological processes regulate the Earth system."It delivers scientific knowledge to help human societies develop in harmony with Earth's environment.In 2004, IGBP published a landmark synthesis, Global Change and the Earth System: A Planet Under Pressure (Steffen et al).Measurements of Earth system processes, past and present, have led to the conclusion that the planet has moved well outside the range of natural variability in the last half million years at least.
