• A personal note on IGBP and the social sciences

    Humans are an integral component of the Earth system as conceptualised by IGBP. João Morais recalls key milestones in IGBP’s engagement with the social sciences and offers some words of advice for Future Earth.
  • IGBP and Earth observation:
    a co-evolution

    The iconic images of Earth beamed back by the earliest spacecraft helped to galvanise interest in our planet’s environment. The subsequent evolution and development of satellites for Earth observation has been intricately linked with that of IGBP and other global-change research programmes, write Jack Kaye and Cat Downy .

Two millennia of sea level data: the key to

predicting change

Sea level reconstructions spanning the late Holocene (the past 2000 years) provide a preindustrial context for understanding the patterns and causes of contemporary and future change. The Intergovernmental Panel on Climate Change (IPCC) assumed that global sea level change during the past two millennia (prior to the middle of the nineteenth century) was close to zero [Bindoff et al., 2007], but understanding of late Holocene sea level variability is limited. Glaciers and ice sheets changed significantly in size during this period, and therefore sea level likely oscillated on the order of several decimeters. In addition, ocean dynamics, solid Earth movements, steric (density) changes, and gravitational effects contributed to complex regional patterns of sea level change.
