Geoengineering and its policy implications were hot topics at this year’s Science in Public conference. The subject raised questions such as how is geoengineering portrayed in the media and what does this mean for the acceptance of geoengineering technologies? Dr Rusi Jaspal and Professor Brigitte Nerlich discuss their research into media representations of geoengineering and how these shape the ...[Read More]
Imaggeo on Mondays: Curaçao’s coral coastline
Easterly trade winds can carry warm moist air to the island of Curaçao, having picked up moisture while crossing the Atlantic Ocean. Lying just south of the hurricane belt, Curaçao can still suffer the effects of these storms. For the most part, though, the coast has experienced little damage, leading to great preservation of the fossil reefs that fringe its coast. The northern coast of Curaçao, w ...[Read More]
Geosciences Column: How curbing HFC emissions could reduce warming
Carbon dioxide is without a doubt the most famous of warming culprits. But would reducing emissions of this greenhouse gas be enough to mitigate climate change within this century? A recent paper published in Atmospheric Chemistry and Physics focuses on a less known substance that, if phased out, could avoid as much as 0.5 °C of warming by 2100. Hydroflurocarbons (HFCs) have an interesting history ...[Read More]
Geosciences Column: Just a drop in the ocean – river nutrients and Arctic plankton
The oceans are a big contributor to the global carbon cycle, with phytoplankton taking up carbon through photosynthesis and incorporating it into their shells. When these organisms die their shells sink and make a calcareous contribution to seafloor sediments. Of course, with the formation of limestone, this carbon is locked out of the atmosphere for long periods of geological time. Until recently ...[Read More]
