Nature, 393, 450-455, 10.1038/30943 information crossReference sciencePaper eng; USA geoscientificInformation Date Range: 1400 CE to 1994 CE; Date Range: 550 cal yr BP to -44 cal yr BP; -180 180 -90 90 1400 1994 STUDY NOTES: The data consists of two timeseries representative of Northern Hemisphere growing season temperatures for the period 1400-1994, derived from means of 383 maximum latewood density chronologies from the northern Boreal forest. Both series are given in dimensionless standardised anomalies, and one has also been rescaled to give an estimate of Northern Hemisphere land and marine temperature anomalies. Updated 7/2003 (Addition of tables 1 & 2, volcanic eruptions data) ABSTRACT SUPPLIED BY ORIGINATOR: A network of temperature-sensitive tree-ring-density chronologies provides circum-hemisphere information on year-by-year changes in summer warmth in different regions of the northern boreal forest. Combining these data into a single time-series provides a good summer-temperature proxy for northern high latitudes and the Northern Hemisphere as a whole. Here we use this well dated, high-resolution composite time-series to suggest that large explosive volcanic eruptions produced different extents of Northern Hemisphere cooling during the past 600 years. The large effect of some recent eruptions is apparent, such as in 1816, 1884 and 1912, but the relative effects of other known, and perhaps some previously unknown, pre-nineteenth-century eruptions are also evaluated. The most severe short-term Northern Hemisphere cooling event of the past 600 years occurred in 1601, suggesting that either the effect on climate of the eruption of Huaynaputina, Peru, in 1600 has previously been greatly underestimated, or another, as yet unidentified, eruption occurred at the same time. Other strong cooling events occurred in 1453, seemingly confirming a 1452 date for the eruption of Kuwae, southwest Pacific, and in 1641/42, 1666, 1695 and 1698.
