Consequences of Global Warming of 1.5 °C and 2 °C for Regional Temperature and Precipitation Changes in the Contiguous United States
Fig 1
Annual mean surface air temperature anomalies relative to 1901-1930 mean for CONUS for 32 models in the CMIP5 multi-model ensemble for RCP4.5 (blue) and RCP8.5 (red).
The ensemble mean and the individual model projections from 2005 to 2099 are shown by colored thin lines and the globally averaged (land+ocean) ensemble mean projections are shown by colored dotted lines. The yellow dotted line indicates the ensemble mean projections across all models and both RCPs. The dotted grey lines indicate the baseline (1901-1930) and 1.5, 2, 3, and 4°C global warming thresholds relative to the baseline. The thick black line shows the observed (CRU) temperature anomalies from 1901-2014 for CONUS. The vertical grey line marks the boundary between historical and RCP CMIP5 simulations.
