Learning from global emissions scenarios

Scenarios of global greenhouse gas emissions have played a key role in climate change analysis for over twenty years. Currently, several research communities are organizing to undertake a new round of scenario development in the lead-up to the Fifth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC). To help inform this process, we assess a number of past efforts to devel...

Interpreting the IPCC Emissions Scenarios

This paper discusses how two sets of emissions scenarios, generated using the Atmospheric Stabilization Framework, were used by the United Nations Intergovernmental Panel on Climate Change (IPCC). In particular it discusses how the scenarios were specified, what roles models played in developing the scenarios, and how the scenarios were interpreted by participants in the IPCC process. It draws ...

Researchers from the Technische Universität München in Germany said they carried out the review because there is a deep mistrust of psychiatry fostered by reports indicating that psychotropic drug efficacy is small. The study, published in the British Journal ...
