Chloritoid is a metamorphic mineral commonly found inside phyllite rocks – which is shale (a type of mudstone containing clays, silts and muds) that has been metamorphosed several times. Confusingly, chloritoid does not actually contain the element chlorine but instead is an iron magnesium manganese alumino-silicate hydroxide. This particular specimen is from Lyon, France: In larger …[Read More]

Geosciences Column: Climate-impact studies and their importance in a world of climatic uncertainty
A new hydrological climate-impact study by Nina Köplin and colleagues, in the European Geosciences Union journal Hydrology and Earth System Sciences, investigates the impacts of climate change on forest expansion and glacier retreat in Switzerland. This study raises important questions as to whether or not land cover changes should be considered as climate change impacts …[Read More]
Imaggeo on Mondays: Travertine takeover
This week’s Imaggeo on Mondays is brought to you by Olivier Galland, who took this photo during an incredible outreach adventure in the Andes… The image displays the spectacular Puente del Inca (The Inca Bridge) hot springs, in the Argentinian Andes of the Mendoza province, along the Vacas River, close to the foot of Cerro …[Read More]
IPCC report ‘unprecedented changes’ in climate, urging policymakers to take action
“Human influence on the climate system is clear” was the key message from the report on the physical science of climate change from the Intergovernmental Panel on Climate Change (IPCC). “We have come a long way since the first IPCC report was published in 1990,” a statement reiterated throughout the press conference for the release …[Read More]
A sky-high view on pollution in the Himalayas: the science
Jane Qiu shares her experience of shadowing atmospheric scientists some 5000 metres above sea level after being awarded the EGU’s science journalism fellowship. To find out how she got there, see her last post, A sky-high view on pollution in the Himalayas: the journey. Lab with a view After six days of strenuous hike, the …[Read More]
Imaggeo on Mondays: Eddy covariance
This week’s Imaggeo on Mondays is brought to you by Jean-Daniel Paris, a meteorologist from the Climate and Environmental Sciences Laboratory (LSCE), France. He describes how new techniques like eddy covariance tell us about the flux of greenhouse gas emissions to the atmosphere… This picture was taken during a visit to the Hyytiälä research station in …[Read More]
Geosciences column: Playing back the Antarctic ice records
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 …[Read More]
