The International Council of Scientific Unions, a coordinating body of national science organizations, launched IGBP in 1987. It looked at the total Earth system, the changes that are occurring, and the manner in which changes are influenced by human actions.
IGBP aimed to describe and understand how the physical, chemical and biological processes regulate the Earth system. It also seeks to increase knowledge of how humans are influencing the global processes, such as the carbon cycle, nitrogen cycle, sulfur cycle, water cycle and phosphorus cycle. "It delivers scientific knowledge to help human societies develop in harmony with Earth's environment."
IGBP research is organised around six projects representing the Earth system - land, atmosphere, ocean and where they meet (land-atmosphere, land-ocean. atmosphere-ocean) and two further projects looking at the Earth system as a whole: Past Global Changes (PAGES) which looks at palaeoclimate, and the Analysis, Integration and Modelling of the Earth System (AIMES), which helps set the agenda for Earth system models. Plus four joint projects - carbon, water, human health and food security - with the other three international global-change programmes.
In 2004, IGBP published a landmark synthesis, Global Change and the Earth System (Steffen et al). The synthesis stated that humanity was now the main driver of change at the planetary scale and that Earth is now operating in a "no analogue" state. 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.
