Regarding variability, the ISPM fails to mention that the IPCC found that the larger «natural climatic variability» is almost all in the direction of cooler temperatures, relative to «previous estimations», for the past millenium: «The additional variability shown in some new studies [since the Third Assesment Report] implies mainly cooler temperatures (predominantly in the 12th to 14th, 17th and 19th centuries), and only one new reconstruction suggests slightly warmer conditions (in the 11th century, but well within the uncertainty range indicated in the TAR).»
