This paper presents the ICLIPS Impacts Tool, a graphical user interface that provides access to a large set of climate impact response functions (CIRFs) from the ICLIPS model, an integrated assessment model of climate change. Its reduced-form impact module is comprised of CIRFs that depict the regional sensitivity of selected climate-sensitive impact sectors to changes in important climatic and atmospheric drivers in biophysical terms. The CIRFs were initially developed to enable the incorporation of thresholds for climate impacts in a tolerable windows analysis with the ICLIPS model. However, they are also a valuable source of information in their own right. The ICLIPS Impacts Tool provides convenient access to a large number (ca. 100,000) of impact diagrams for a wide range of impact indicators, geographical regions, and climate projections. The choice of Java as programming language enables the ICLIPS Impacts Tool, which is distributed on a CD-ROM, to run on the most common computer platforms, including Microsoft Windows, Mac OS X, Linux, Solaris, and AIX.
