Based in Stockholm, the International Geosphere-Biosphere Programme (IGBP) studies a wide range of interactions between both biological and physical processes and interactions with human systems. Their research agenda is impressive, and visitors to their homepage can dive right into their materials by reading one of their recent newsletters or by looking at the news updates. In the "Resources" area, visitors can download some of the IGBP's research reports and browse some of their recent conference presentations. Scientists and policy analysts alike will want to look at the "Earth System Science Partnership" area in order to learn more about their very ambitious work towards an "integrated study of the Earth System." This is being done in partnership with three additional international global change research institutions, and it is well worth a look.
