• 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 .

Implications of large-scale iron fertilization of the oceans

Vol. 364; pp. 213-309.

A historical perspective of the scientific study of ocean iron fertilization (OIF) over the last 15 yr prefaces a short synthesis of the multi-faceted issues raised by the 11 contributions to this Theme Section. These issues, which range from ethical to logistical, must be aired in discussions surrounding OIF and its commercial application as a potential climate mitigation tool. Two other issues, not considered in detail by the contributors, are also addressed: (1) the importance of the rate of change in atmospheric CO2 following sustained global OIF (other than model simulations, the only data presently available to assess this comes from the geological record, e.g. Vostok ice core record of dust supply and atmospheric CO2); and (2) the necessity of making realistic estimates of the cost of OIF (i.e. carbon sequestered per unit of iron added) to provide comparisons of the ratio of cost:environmental risk of OIF with other mitigation strategies.
