Satellites are keeping tabs on the state of Arctic and Antarctic sea ice, and have observed considerable declines in ice extent in many areas since records began, but what do we know of past sea ice extent? Ice cores keep an excellent record of climate change, but until recently, ice cores have not been used to quantify patterns in past sea ice extent because few reliable compounds are preserved i ...[Read More]

Friday Photo (98) – Hydroelectric Energy in Ladakh
Hydroelectric power plants are being developed across the Himalayas. Here, a small-scale system is used to store energy during times of peak supply from other sources, and deliver energy during times of peak demand. This system relies on the shuttling of river water (seen in the background) between different elevations. (c) Geology for Global Development 2013

Science Snap (5): Volcan de Colima’s lava dome
This photograph, taken from a helicopter, is of the lava dome at Volcan de Colima volcano, Mexico in November 2009. Volcan de Colima has been active throughout history with over 40 eruptions since the sixteenth century. The last explosive Plinian eruption was in 1913 blasting out the summit crater. Nowadays, eruptions tend to be effusive with eruptions of lava flows and the gradual build up of the ...[Read More]

A sky-high view on pollution in the Himalayas: the journey
After being awarded the EGU’s science journalism fellowship, Jane Qiu took to the Himalayas to shadow scientists studying air pollution at the Pyramid Observatory some 5000 metres above sea level. The journey to work is by no means an easy one… For Angela Marinoni and Paolo Bonasoni, climate scientists at the Institute of Atmospheric Sciences and Climate in Bologna, Italy, and Maxime Hervo, a Ph.D ...[Read More]

Guest Blog: A Summer of Volcanic Observation in Ecuador (4)
David Litchfield completed a second undergraduate degree in Geosciences with the Open University and is currently studying part-time for an MSc in Geophysical Hazards at UCL. He has a broad interest in hazard monitoring methods and how geoscientists communicate their findings with those who need it, and retains a strong connection with the Andean highlands of Ecuador. This summer, David is volunte ...[Read More]

Imaggeo on Mondays: Great faults and faultless geotourism
Road cuttings provide a great window into the wonders of what’s beneath the Earth’s surface. In this week’s Imaggeo on Mondays Bahram Sadry takes us through a beautiful fault between Tabriz and Tehran, Iran… These incredible rock outcroppings along Zanjan-Tabriz highway (the northwest of Iran), are unlike any other outcrop in the world. They are a group of faults and fractures, brecciation and gra ...[Read More]

Blog Competition (1st Prize) – Philip Irwin: In Unity We Trust
For our Blog Competition 2013, we asked for people to submit articles addressing one of two topics. Philip Irwin’s article makes an argument for the inclusion of development education in geoscience courses, and it won first prize in its category. Philip did BSc Geology at Durham University where he developed an interest in environmental hazards. He then spent some time travelling to places ...[Read More]

Biomass burning birthday
Last September I spent a month in Brazil for a research project aiming to study the pollution produced by deforestation fires in the Amazon Basin. The fires are mainly started by people for agricultural needs or land clearing for buildings and infrastructure. These fires produce huge amounts of smoke that blanket vast regions of South America during the “dry” season, which can lead to ...[Read More]

Climate change: it’s just a matter of time!
Natural or man-made: what factors are responsible for the climate changes we are seeing today? Ahead of the release of the latest IPCC report next week, Marion Ferrat discusses the different factors affecting climate change and shows that who takes the blame all depends on timing… Over the past century, our planet’s climate system has been changing. Changes in the composition of the atmosphere, ho ...[Read More]
