What connects a series of volcanic eruptions and severe summer cooling with a century of pandemics, human migration and the rise and fall of civilisations? Tree rings, says Ulf Büntgen, who leads Cambridge’s first dedicated tree-ring laboratory in the Department of Geography.
Using ancient DNA, researchers have created a unique picture of how a prehistoric migration route evolved over thousands of years – revealing that it could not have been used by the first people to enter the Americas, as traditionally thought.
Increase in volcanic eruptions at the end of the ice age caused by melting ice caps and glacial erosion02 Feb 2016
Researchers have found that glacial erosion and melting ice caps both played a key role in driving the observed global increase in volcanic activity at the end of the last ice age.
A new study of how the structure of the ocean has changed since the end of the last ice age suggest that the melting of a vast ‘lid’ of sea ice caused the release of huge amounts of carbon dioxide into the atmosphere.
Populations of hunter-gatherers weathered Ice Age in apparent isolation in Caucasus mountain region for millennia, later mixing with other ancestral populations, from which emerged the Yamnaya culture that would bring this Caucasus hunter-gatherer lineage to Western Europe.
Study successfully reconstructed temperature from the deep sea to reveal how global ice volume has varied over the glacial-interglacial cycles of the past 1.5 million years.
Scientists have found the possible source of a huge carbon dioxide "burp" that happened some 18,000 years ago and which helped to end the last ice age.
