This year the EGU embarked on a new journey into Africa to deliver its renowned Geosciences Information for Teachers (GIFT) programme to teachers in South Africa and neighbouring countries in collaboration with UNESCO and the European Space Agency (ESA). The topic: Climate Change and Human Adaptation. Jane Robb reports on the week’s events… Set in ‘the windy city’ of Port Elizabeth (or ...[Read More]
Imaggeo on Mondays: Exploring the East African Rift

While the wonders of the African atmosphere feature in his photography, the East African Rift has a much bigger tale to tell. Drawing from all aspects of geoscience Alexis shares its story… This picture shows Kilimanjaro, Africa’s highest mountain, at sunrise. ...[Read More]
Geosciences Column: Shifting the O in H2O
Wherever you are in the world’s oceans, you can identify particular bodies of water (provided you have the right equipment) by how salty they are. You can get a feel for how productive that part of the ocean is by measuring a few chemical components in the water column. And, year on year, you will see a recurring pattern in how things like temperature, salinity and oxygen content vary with depth. ...[Read More]
Geosciences Column: Using tall trees to tot up tropical carbon
Forests in the tropics account for about half the above-ground carbon on Earth and as the trees grow older they are capable of storing more and more. In fact, their carbon-storing potential is so large that they are increasingly being viewed as a means of mitigating climate change. Take, for example, the United Nations effort to reduce degradation and deforestation by assigning value to forest car ...[Read More]
