Figure 2. (top) Fractional changes (%) of precipitation and the maximum amount of water in the atmosphere as projected by seven state-of-the-science climate models (CMIP5). These are multi-model mean differences (future minus present) in the 30-year period maximum daily precipitation for 2071–2100 under a business as usual emissions scenario (RCP8.5) scenario, relative to the 1971–2000 reference value. (bottom) A scatterplot of grid point differences (future minus present) of the 30-year maximum amount of water in the atmosphere versus 30-year average temperature of the climatologically warmest month in the lower atmosphere (850hPa) for 2071–2100 with respect to 1971–2000 for the business as usual emissions scenario (RCP8.5). The straight line represents a slope of 6.3%/⁰C (from Kunkel et al., 2013).
