New research shows that natural accumulations of carbon dioxide (CO2) that have been trapped underground for around 100,000 years have not significantly corroded the rocks above, suggesting that storing CO2 in reservoirs deep underground is much safer and more predictable over long periods of time than previously thought, explains Suzanne Hangx a postdoctoral researcher at the University of Utrech ...[Read More]

Imaggeo on Mondays: A solitary floating island

Laura Roberts-Artal January 19, 2015

With 2014 officially named the hottest year on record, there is evidence of the effects of rising global temperatures across the globe. The solitary, shimmering iceberg in today’s Imaggeo on Mondays photograph is a reminder that one of the best places to look for evidence of change is in glaciers. Daniela Domeisen tells the story of this lonely frozen block of ancient ice. The picture shows an ice ...[Read More]

IPCC report ‘unprecedented changes’ in climate, urging policymakers to take action

Sara Mynott October 4, 2013
