Galileo Galilei, after whom the conferences are named

EGU Galileo Conference programme: call for proposals

  • EGU news
  • 27 November 2019

The EGU is now accepting proposals for Galileo Conferences, which aim to address well-focused cutting-edge topics at the frontier of geosciences research. The conferences are informal: the state-of-the-art is outlined in keynote talks designed to trigger in-depth discussion of important aspects of the conference topic. EGU members can propose to organise a Galileo Conference and apply for funding by 29 February 2020.

Societal breakdown as an emergent property of large-scale behavioural models of land use change

Concerns are growing that human activity will lead to social and environmental breakdown, but it is hard to anticipate when and where such breakdowns might occur. We developed a new model of land management decisions in Europe to explore possible future changes and found that decision-making that takes into account social and environmental conditions can produce unexpected outcomes that include societal breakdown in challenging conditions.

First reported case of thunderstorm asthma in Israel

During severe thunderstorms, cold outflows can eject pollen and dust particles from the surface, releasing allergens and causingthunderstorm asthmaepidemics in sensitive populations. We report the first case in Israel that occurred on 25 October 2015. The emergency room presentation records from three hospitals in central Israel showed a clear increase in patients with respiratory complaints immediately after the passage of a massive super-cell thunderstorm in the area.

The diurnal cycle of the smoky marine boundary layer observed during August in the remote southeast Atlantic

Boundary layer (BL) semi-direct effects in the remote SE Atlantic are investigated using LASIC field measurements and satellite retrievals. Low-cloud cover and cloud liquid water path decrease with increasing smoke loadings in the BL. Daily-mean surface-based mixed layer is warmer by 0.5 K, moisture accumulates near the surface throughout the night, and the BL deepens by 200 m, with LWPs and cloud top heights increasing, in the sunlit morning hours, as part of the smoke-altered BL diurnal cycle.

Can we use sea surface temperature and productivity proxy records to reconstruct Ekman upwelling?

We test two assumptions that are often made in paleoclimate studies by using observations and ask whether temperature and productivity proxy records in the Southern California Current can be used to reconstruct Ekman upwelling. By examining the covariation between alongshore wind stress, temperature, and productivity, we found that the dominant covarying pattern does not reflect Ekman upwelling. Other upwelling patterns found are timescale dependent. Multiple proxies can improve reconstruction.

Cryo History – How airborne glaciologists measured the movement of glaciers before the satellite era

Cryo History – How airborne glaciologists measured the movement of glaciers before the satellite era

Recent work published in my department at the Geological Survey of Denmark and Greenland (GEUS) focused on solid ice discharge into the ocean from the Greenland Ice Sheet from 1986 to 2017 (Mankoff et al. 2019). Solid ice discharge is the ice that is lost from a glacier as it flows towards the coast and eventually breaks off as icebergs into the ocean (i.e. calving). Solid ice discharge is an important constraint for sea level rise predictions. Today, we use …

The Sassy Scientist – Seeking Specials

Every week, The Sassy Scientist answers a question on geodynamics, related topics, academic life, the universe or anything in between with a healthy dose of sarcasm. Do you have a question for The Sassy Scientist? Submit your question here or leave a comment below. Feeling kind of special after her paper got published, Marie-Jeanne asked: How do you feel about special issues? Dear Marie-Jeanne, Underwhelmed. Seriously. What is the point of special issues? Nowadays, I mean. I get that – …


Dear “climate sceptic”, do you have a fire insurance? – Climate policy under uncertainty

Dear “climate sceptic”, do you have a fire insurance? – Climate policy under uncertainty

One often hears that ambitious climate policy might be premature while climate change is still “uncertain”. This sounds like a fair argument: The amount of global warming per doubling CO2 is not well constrained, and the amount of economic damage per degree of warming even less. But is this uncertainty a sound excuse to wait and see? Uncertainty, risk aversion, and insurance If you knew the winning combination of this week’s lottery, you would surely buy a lot. If you …
