Figure 5. Time reconstructions (solid lines) along with raw data. (a) Principal Components (RPCs) 1-5 (b) Northern hemisphere mean temperature (NH) in oC. In both cases, the zero line corresponds to the 1902-1980 calibration mean of the quantity. For (b), raw data is shown through 1995 and positive and negative 2E uncertainty limits are shown by the light dotted lines surrounding the solid reconstruction, calculated as described in the Methods section.
