International climate policy post-Copenhagen is in crisis. There is currently no prospect of the comprehensive and binding UN climate treaty

This policy paper shows how the current deadlock in international climate policy can be broken. A resolute course must be set in the international climate process within the next few years in order to keep the global mean temperature rise below 2

The German Advisory Council on Global Change (WBGU) has developed an innovative approach to solving the problem of climate change. A key component is an agreement between the community of states regarding a cap for the total amount of

In view of the major opportunities and risks associated with it, and the complexity of the subject, bioenergy policy has in a short time become a challenging political task for regulators and planners

This report summarizes the state-of-the-art of science on the subject of “Climate Change as a Security Risk”.

This flagship report, summarizes the state-of-the-art of science on the subject of 'Climate Change as a Security Risk'. It is based on the findings of research into

Surface and groundwater that cross international boundaries present increased challenges to regional stability because hydrologic needs can often be overwhelmed by political considerations. While the potential for paralyzing disputes is especially high in these basins, history shows that water can catalyze dialogue and cooperation, even between especially contentious riparians. There are 263 rivers around the world that cross the boundaries of two or more nations, and untold number of international groundwater aquifers. In order to understand the long term implications of transboundary water management, and the potential for future conflict and cooperation, it is critical to assess what the indicators and triggers are of such processes currently, then evaluate their prospects for the future.

This special report does not seek to paint a comprehensive picture of the state of the oceans. It does not set out to recapitulate the many years of debate on ocean overfishing. WBGU concentrates instead on those key linkages between climate change and the oceans that are the topic of new scientific insights.These insights include new findings on warming, ocean currents, sea-level rise, carbon uptake and acidification, and on the impacts of these factors upon marine ecosystems.The report also discusses in detail the development of tropical cyclones, the issues surrounding carbon storage in the ocean or under the seabed, and the risks associated with methane hydrate deposits in the sea floor. Many of these issues are closely interlinked
