Geosciences Column: Using volcanoes to study carbon emissions’ long-term environmental effect

In a world where carbon dioxide levels are rapidly rising, how do you study the long-term effect of carbon emissions? To answer this question, some scientists have turned to Mammoth Mountain, a volcano in California that’s been releasing carbon dioxide for years. Recently, a team of researchers found that this volcanic ecosystem could give clues to how plants respond to elevated levels of carbon d ...[Read More]

GeoPolicy: EGU sciences on debate at the European Parliament

GeoPolicy: EGU sciences on debate at the European Parliament

The adoption of legislation within the European Union (EU) is a complex process involving many steps. In my first blog post in this GeoPolicy series I highlighted an example of this process. Several draft legislation pieces are currently being assessed within the European Parliament (EP) and Council of Ministers (Council) that have been influenced by EGU-related science. This blog post summarises ...[Read More]

GeoTalk: Talking about ‘ocean burps’ with James Rae

GeoTalk: Talking about ‘ocean burps’ with James Rae

Trying to understand the reasons behind the global warming of our climate is a never ending quest for scientists across the geosciences. Scientists often rely on deciphering past change to help us understand, and perhaps predict, what might happen in the future. Many will be familiar with the common saying ‘the past is the key to the future’. This is exactly what James Rae, a research fellow at th ...[Read More]

Imaggeo on Mondays: How sea urchins can help mitigate climate change

This week’s Imaggeo on Mondays stars the humble sea urchin – a creature suffering from the effects of climate change, but one that could also provide a way to sequester some of the CO2 responsible… Carbon dioxide and water react to form carbonic acid – a mixture of bicarbonate and hydrogen ions. Sea urchins bag the bicarbonate to grow bigger, stronger shells, or ‘tests’, but without a catalyst, th ...[Read More]
