This brief provides an overview of future climate change in Tanzania, using results from the latest available climate model simulations. The UMFULA research team of the Future Climate for Africa (FCFA) programme has analysed 34 Global Climate Models (GCMs) that provide projections for Tanzania to try to distill robust messages and some key trends that may help planning and decision-making. Firstly, a summary is presented of recent observed rainfall and temperature variability. This is followed by an overview of the range of climate projections available from the leading source of climate model results. A detailed annex describes the methods and data sets used in the brief and presents a wider range of figures for further reference. A two-page summary also highlights key findings.
