UNEP Year Book 2009

New Science and Developments in Our Changing Environment

The UNEP Year Book 2009 presents work in progress on scientific
understanding of global environmental change, as well as foresight
about possible issues on the horizon. The aim is to raise awareness of the
interlinkages among environmental issues that can accelerate the rates
of change and threaten human wellbeing.

The UNEP Year Book 2009 examines in six chapters new science and developments, and discusses the cumulative effects expected from degradation of ecosystems, the release of substances harmful to those ecosystems and to human health, the consequences of our changing climate, the continued human and economic loss resulting from disasters and conflicts, and the overexploitation of resources. It calls for an intensified sense of urgency for responsible governance in the face of approaching critical thresholds and tipping points.
