GeoPolicy: EGU sciences on debate at the European Parliament

GeoPolicy: EGU sciences on debate at the European Parliament

The adoption of legislation within the European Union (EU) is a complex process involving many steps. In my first blog post in this GeoPolicy series I highlighted an example of this process. Several draft legislation pieces are currently being assessed within the European Parliament (EP) and Council of Ministers (Council) that have been influenced by EGU-related …[Read More]

GeoTalk: Talking about ‘ocean burps’ with James Rae

GeoTalk: Talking about ‘ocean burps’ with James Rae

Trying to understand the reasons behind the global warming of our climate is a never ending quest for scientists across the geosciences. Scientists often rely on deciphering past change to help us understand, and perhaps predict, what might happen in the future. Many will be familiar with the common saying ‘the past is the key …[Read More]

Imaggeo on Mondays: The warming

Imaggeo on Mondays: The warming

Events of meteorological significance, such as thunderstorms, hurricanes, cyclones, jet streams and global-scale circulations can be described by a general term: atmospheric dynamics. When it comes to it, atmospheric dynamics deals with nothing more than air, which, in truth, is very difficult to directly observe, (with the exception of clouds and precipitation). This makes the …[Read More]

Imaggeo on Mondays: Strombolian eruption

Jonas Kuhn, a researcher at Heidelberg University , took the photograph during a field campaign at Stromboli volcano in Italy. The objective of this campaign was to gather data from different gaseous compounds of the volcanic plume. Via emission fluxes of volcanic gases (e.g. SO2, CO2, halogen compounds…) or the ratio of emitted gases, one …[Read More]
