Scientists zero in on the role of volcanoes in the demise of dinosaurs

30 March 2021

Researchers have uncovered evidence suggesting that volcanic carbon emissions were not a major driver in Earth’s most recent extinction event. Earth has experienced five major extinction events over the last 500 million years, the fifth and most recent responsible for wiping out the dinosaurs 66 million years ago. Massive...

Traces of Earth’s early magma ocean identified in Greenland rocks

12 March 2021

New research led by the University of Cambridge has found rare evidence – preserved in the chemistry of ancient rocks from Greenland - which tells of a time when Earth was almost entirely molten. The study yields information on a fundamental period in our planet’s formation, when a deep sea of incandescent magma stretched...

Hubble sees new atmosphere forming on a rocky exoplanet

11 March 2021

For the first time, scientists using the NASA/ESA Hubble Space Telescope have found evidence of volcanic activity reforming the atmosphere on a rocky planet around a distant star. The planet, GJ 1132 b, has a similar density, size, and age to Earth. The planet GJ 1132 b appears to have begun life as a gaseous world with a...

Mapping Cambridge building stone

10 March 2021

A comprehensive survey of the stone used in Cambridge buildings has been made by Nigel Woodcock and Euan Furness from Cambridge Earth Sciences. The results show how stone use through time was influenced by wars, by pandemics, and by the canal and railway revolutions. The survey’s novel methodology will be useful for...

New calculations show volcanoes are key cause of hydrogen in early atmospheres

3 March 2021

Scientists may soon be able to tell whether distant exoplanets are home to volcanoes, and even the early stages of life, just by looking for hydrogen gas in their atmospheres. Research from Cambridge Earth Sciences has found that volcanic activity on planets with a similar size and interior to Earth can create atmospheres...

Panel discussion: can we adapt to a changing climate?

22 February 2021

A recent panel discussion held by the Royal Society, in partnership with the British Museum, explored how humans adapted to environmental change in the past, and what we should be doing in the present to reduce our vulnerability to climate change. Throughout history, humanity's survival has depended, in part, on our...

New geomagnetic timescale through the Early Palaeozoic Icehouse

9 February 2021

The Geomagnetic Polarity Timescale that charts the reversals of Earth’s magnetic field is well established for the past 200 million years, but increasingly patchy before that. In recent papers in Palaeogeography, Palaeoclimatology, Palaeoecology, scientists have reported the first reliable polarity timescale for later...
