Multi-proxy dating the ‘Millennium Eruption’ of Changbaishan to late 946 CE

Ranking among the largest volcanic eruptions of the Common Era (CE), the ‘Millennium Eruption’ of Changbaishan produced a widely-dispersed tephra layer (known as the B-Tm ash), which represents an important tie point for palaeoenvironmental studies in East Asia. Hitherto, there has been no consensus on its age, with estimates spanning at least the tenth century […]

Volcanology: Chronicling a medieval eruption

The climatic response to the eruption of the Samalas Volcano in 1257 has been elusive. Medieval archives tell of a spatially variable reaction, with Europe and Japan experiencing severe cold compared to relative warmth in North America. The eruption of Samalas Volcano in Indonesia in 1257 was one of the largest in the history of human […]

Climate and hydrology over the past 10 000 years – a story told by peat, pollen and tree rings

CLIMPEAT is a Lithuanian-Swiss cooperative project that aims to explore the interconnections and interdependencies of peatland ecosystems with climate, anthropogenic activity and sequestered carbon. To access detailed information about peatland ecosystems over thousands of years, annual growth rings of trees buried in peat have been analyzed. These trees can be extremely well-preserved and are sometimes […]

Climate sensitivity of shrub growth across the tundra biome

An international team of scientists at 37 sites in nine countries, led by the University of Edinburgh, studied records of shrub growth spanning 60 years by analysing annual growth rings in the plant stems, to explore links between climate and vegetation change. Studies of tundra shrubs — which act as a barometer of the Arctic […]

Sierra Nevada Snowpack Reached Five-Century Low This Year

The 2015 record low snowpack level in California’s Sierra Nevada mountain range is unprecedented in comparison to the past 500 years, according to a new paper published in Nature Climate Change (link is external). In their examination of paleoclimate tree-ring based records dating back to 1500, scientists from the University of Arizona, University of Arkansas, […]
