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 on hydrological systems, N ...[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 of the report. The IPCC were keen to register the significance of ...[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 Finland in June 2010. This station runs flux ...[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 to quantify patterns in past sea ice extent because few reliable compounds are preserved i ...[Read More]
