  author={Keith R. Briffa and P. D. Jones and Fritz Hans Schweingruber and Timothy J. Osborn},
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… Expand

Surface climate responses to explosive volcanic eruptions seen in long European temperature records and mid-to-high latitude tree-ring density around the Northern Hemisphere
Explosive volcanic eruptions are known to have an impact on surface temperatures in the two to three years after the eruption, but our ability to determine the impact is impeded by the paucity ofExpand
European summer temperature response to annually dated volcanic eruptions over the past nine centuries
The drop in temperature following large volcanic eruptions has been identified as an important component of natural climate variability. However, due to the limited number of large eruptions thatExpand
Volcano-induced regime shifts in millennial tree-ring chronologies from northeastern North America
A new network of millennial tree-ring chronologies from the taiga of northeastern North America is presented, which fills a wide gap in the network of the Northern Hemisphere's chronologies suitable for temperature reconstructions and supports the hypothesis that volcanoes triggered both the onset and the coldest episode of the Little Ice Age.

Cool North European summers and possible links to explosive volcanic eruptions
[1] Exactly dated tree-ring measurements such as ring width (TRW) and maximum latewood density (MXD), which are sensitive to summer temperatures, can provide possible routes to investigate theExpand
Northern Hemisphere temperature anomalies during the 1450s period of ambiguous volcanic forcing
Ice core-based estimates of past volcanic eruptions are the main forcing of the last millennium climate model simulations. Understanding the timing and magnitude of eruptions is thus critical forExpand
Dynamic winter climate response to large tropical volcanic eruptions since 1600
[1] We have analyzed the mean climate response pattern following large tropical volcanic eruptions back to the beginning of the 17th century using a combination of proxy-based reconstructions andExpand
Estimates of volcanic-induced cooling in the Northern Hemisphere over the past 1,500 years
Explosive volcanism can alter global climate, and hence trigger economic, political and demographic change1, 2. The climatic impact of the largest volcanic events has been assessed in numerousExpand
Volcanic Eruptions over the Last 5,000 Years from High Elevation Tree-Ring Widths and Frost Rings
Some tree-ring records, due to their great age, the annual resolution of their dates, and their sensitivity to the climatic effects of large volcanic eruptions, are useful in understanding theExpand
Volcanic Signals in Temperature Reconstructions Based on Tree-Ring Records for North and South America
Publisher Summary High-resolution, well-dated proxy records can extend the climatic information available for analysis for centuries or even millennia. Several reconstructed temperature seriesExpand
The impact of volcanic forcing on tropical temperatures during the past four centuries
The effect of volcanism on low-latitude climate has been difficult to quantify. A compilation of tropical and subtropical annually resolved climate reconstructions shows a correlation between low seaExpand


Tree-ring evidence of the widespread effects of explosive volcanic eruptions
Tree-ring evidence from 97 sites over North America and Europe are used to develop a chronology of widespread cool summers since 1600. Averaging annual maximum-density information from theExpand
Tree-Ring Density Reconstructions of Summer Temperature Patterns across Western North America since 1600
Abstract Summer half-year (April-September) mean temperatures are reconstructed across western North America between 1600 and 1982. The reconstructions, ultimately in the form of gridpoint anomalyExpand
Reduced sensitivity of recent tree-growth to temperature at high northern latitudes
Tree-ring chronologies that represent annual changes in the density of wood formed during the late summer can provide a proxy for local summertime air temperature. Here we undertake an examination ofExpand
Ice core evidence for an explosive tropical volcanic eruption 6 years preceding Tambora
High-resolution analyses of ice cores from Antarctica and Greenland reveal an explosive volcanic eruption in the tropics in A.D. 1809 which is not reflected in the historical record. A comparison inExpand
Tree-ring evidence for climatically effective volcanic eruptions

Global influence of the AD 1600 eruption of Huaynaputina, Peru
It has long been estabished that gas and fine ash from large equatorial explosive eruptions can spread globally, and that the sulphuric acid that is consequently produced in the stratosphere canExpand
