a, b Carbon dioxide (CO2) concentrations in parts per million (ppm), (c, d) total radiative forcing (relative to 1861–1880) in watts per square meter (W per m2), (e, f) surface air temperature (relative to 1861–1880) in degrees Celsius (C), and (g, h) precipitation (relative to 1861–1880) in millimeters (mm) per day. Shown for each ensemble scenario (Reference in magenta, ParisForever in blue, Paris2C in yellow and Paris1.5 C in green; shaded areas represent 90% probability bounds; lines are the medians).
