New computer model simulations identify widespread changes in climate variability under sustained anthropogenic forcing. Researchers ran multiple simulations over the period of 1850-2100, working with a “business-as-usual” scenario for strong emissions of greenhouse gases over the 21st century. The study was published today in Earth System Dynamics.
The European Geosciences Union is honouring 50 people at all stages of their careers who have made substantial contributions to the Earth, planetary, and space sciences.
The EGU Outreach Committee has named three Public Engagement Grant winners this year: a card game of geological time, space weather teaching kits for blind and visually impaired students and a musical about climate change!
Venture into space! Learn more about why we study space science with Joby Hollis, meet the Planetary Sciences Division ECS rep Joshua Dreyer and submit your abstract to EGU22!
The Union is hiring an Events Co-ordinator to support our Programme Committee in planning the annual General Assembly and other EGU events run throughout the year. Applications will be reviewed from 16 November 2021 until the position is filled.
Managing water demand and supply during droughts is complex, as highly pressured human–water systems can overuse water sources to maintain water supply. We evaluated the impact of drought policies on water resources using a socio-hydrological model. For a range of hydrogeological conditions, we found that integrated drought policies reduce baseflow and groundwater droughts most if extra surface water is imported, reducing the pressure on water resources during droughts.
Temperate biomes in Europe are not prone to recurrent dry and hot conditions in summer. However, these conditions may become more frequent in the coming decades. Because stress conditions can leave legacies for many years, this may result in reduced ecosystem resilience under recurrent stress. We assess vegetation vulnerability to the hot and dry summers in 2018 and 2019 in Europe and find the important role of inter-annual legacy effects from 2018 in modulating the impacts of the 2019 event.
Aerosol particle pH is well-buffered by alkaline compounds, notably NH3 and crustal elements. NH3 is found to supply remarkable buffering capacity on a global scale, from the polluted continents to the remote oceans. Potential future changes in agricultural NH3 must be accompanied by strong reductions of SO2 and NOx to avoid particles becoming highly acidic, with implications for human health (aerosol toxicity), ecosystems (acid deposition), clouds, and climate (aerosol hygroscopicity).
At the edge of the Greenland Ice Sheet, surface melt releases old layers of dust, that have travelled thousands of years into the ice. Under sunny weather, the dust heats up with radiation, melts the ice underneath, and thus accumulates in tiny potholes and meltwater creeks. However, this photo was taken after a rainy day. The rain triggered increased melt on the surface of the ice irrelevant of its color, resetting this miniature drainage system, but enhancing larger-scale drainage features. …
It’s Christmas! Time for celebration! Time to write your EGU abstract! Time to unwrap your presents! And for some, time to start writing yor PhD dissertation! Rudoplh is one of the lucky ones! But he has a question: How should I start on my PhD dissertation? Dear Rudy, What better time to get started on your dissertation than during the Christmas holidays? I recommend to start writing during the Christmas of your second PhD year. So you can be visited …
With 2021 coming to an end, we wanted to wrap up the year with a blog post summarizing all the things that happened within the Geodesy division. And, although we are still in the middle of a pandemic, there are a number of things to look forward to in 2022! Looking back on 2021 New Division Team 2021 was a year with many changes in the Geodesy Division. Outgoing Division President Johannes Böhm handed over to Annette Eicker (who was …
