In 1877, the United States Geological Survey published a report “On the Geology of the Henry Mountains”, on the small range of peaks in southern Utah, pictured here. Up to that point, little scientific study had been made of the unassuming peaks, but the author of the report, one Grove Karl Gilbert, not only detailed the structure and mineralogy of the landscape, but in doing so also l ...[Read More]

Storm fronts arrive on Britain’s west coast in waves throughout the winter (and very often the summer too!) It is not unusual to see rain falling on a beach with hail and snow lying, whilst a rainbow pierces the clouds. Description by Mary Gagen, as it first appeared on imaggeo.egu.eu. Imaggeo is the EGU’s online open access geosciences image repository. All geoscientists (and others) can su ...[Read More]

Our climate is constantly changing, and with the help of simulation modelling, scientists are working hard to better understand just how these conditions will change and how it will affect society. Science journalist Conor Paul Purcell has worked on Earth System Models during his time as a PhD student and postdoctoral researcher; today he explains how scientists use these models as tools to foreca ...[Read More]

Living in a new Age

Living in a new Age
The International Commission on Stratigraphy (ICS) has updated the timeline for Earth’s full geologic history, dividing the Holocene into three distinct periods. What does that mean for the Anthropocene? (Photo: East Khasi Hills in Megahalaya, India. The state is the namesake of the new geological age. Credit: Sai Avinash via Wikimedia Commons)

If you were suddenly told you were living in a different time period, what would your immediate reaction be? Changes in the calendar – even if it’s just terminology – have proven emotive in the past. In 1752, when England shifted from the Julian to Gregorian calendars, and 11 days were cut from 1752 to catch up, there are suggestions that civil unrest ensued. Once again, the name of the period in ...[Read More]
