Accelerated tree growth caused by a warming climate does not necessarily translate into enhanced carbon storage, an international study suggests.

The 2019 Cambridge Science Festival is set to host more than 350 events as it explores a range of issues that affect today’s world, from challenges around climate change policy, improving safety and quality in healthcare, and adolescent mental health, to looking at what the next 25 years holds for us and whether quantum computers can change the world.

Memories of the largest lava flood in the history of Iceland, recorded in an apocalyptic medieval poem, were used to drive the island’s conversion to Christianity, new research suggests. 

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.

Truffles are one of the world’s most expensive ingredients, and also one of the most mysterious. Now, with the help of a 170-year-old ‘living laboratory’, and a dog called Lucy, researchers hope to unearth new understanding of the secret life of these underground delicacies.

The Mediterranean black truffle, one of the world’s most expensive ingredients, has been successfully cultivated in the UK, as climate change threatens its native habitat.

An international group of researchers has dated a large volcanic eruption in Iceland to within a few months. The eruption, which is the oldest volcanic eruption to be precisely dated at high northern latitudes, occurred shortly before the first permanent human settlements were established, when parts of the now mostly treeless island were still covered with forest.
