Abstract The Novel Climates map depicts the development of novel 21st-century climates, climates that include conditions not experienced at present. Novel Climates and its companion maps, Disappearing Climates and Local Climate Change, were created by John W. Williams, Stephen T. Jackson, and John E. Kutzbach and described in "Projected distributions of novel and disappearing climates 2100 AD," published by PNAS. The ten maps in the collection cover two different ranges of C02 increase (A2 at 856 ppm, and B1 at 549 ppm), and three different ways of viewing the data: novel climates, disappearing climates, and local changes. The map value is a standardized scalar index of climate dissimilarity (SED) between the end of the 20th and the end of the 21st centuries. The climate variables used in the model were temperature and precipitation for both the June-August and December-February periods. The map series also contains A2 and B1 scenarios at 500km - the pool of potential analogs is restricted to gridpoints within 500 km of each target gridpoint. Novel climates, as modeled in this series, are projected to develop primarily in the tropics and subtropics, and will occupy a spatially cohesive subset of areas experiencing high local climate change. Maps in the series were based on the Intergovernmental Panel on Climate Change (IPCC) Special Report on Emissions A2 and B1 scenarios. Map data was converted for use in TerraViva!® global data-viewing software by ISCIENCES, L.L.C., Ann Arbor, Michigan, USA.
Supplemental Information The downloadable zip file contains the collection of ten maps at 2.8 degrees resolution. System requirement: To use the downloadable data files (*.xtvm) you must have TerraViva!® Global Data Viewer or TerraViva!® Global Data Analyst software installed. A free copy of TerraViva!® Global Data Viewer is available at www.terraviva.net. The collection includes: four Novel Climates maps, four Disappearing Climates maps, and two Local Climate Change maps. For more information see below: Distribution Info > Online Resource > Data for Download > "Projected distribution of novel and disappearing climates by 2100AD."
Purpose Novel Climates and its companions, Local Climate Change and Disappearing Climates, were created based on emissions scenarios produced for the fourth assessment report of the IPCC, with the goal of identifying regions projected to experience (i) high magnitudes of local climate change, (ii) development of novel 21st-century climates,and/or (iii) the disappearance of extant climates.
