The EGU Outreach Committee promotes the Earth, planetary and space sciences and the activities of the EGU among scientists, the public, policymakers and all other interested individuals and organisations. The Committee seeks 3–4 new members to help further its programme.


Boreal forest fire in Canada

Air pollution in New York City linked to wildfires hundreds of miles away

  • Press release
  • 21 January 2020

A new study published in the European Geosciences Union (EGU) journal Atmospheric Chemistry and Physics shows that air pollutants from the smoke of fires from as far as Canada and the southeastern U.S. traveled hundreds of miles and several days to reach Connecticut and New York City, where it caused significant increases in pollution concentrations.

Variations in soil chemical and physical properties explain basin-wideAmazon forest soil carbon concentrations

Amazon soils hold as much carbon © as is contained in the vegetation. In this work we sampled soils across 8 different Amazonian countries to try to understand which soil properties control current Amazonian soil C concentrations. We confirm previous knowledge that highly developed soils hold C through clay content interactions but also show a previously unreported mechanism of soil C stabilization in the younger Amazonian soil types which hold C through aluminium organic matter interactions.

A multi-model analysis of teleconnected crop yield variability in a range of cropping systems

In this study, we analyse the impacts of three major climate oscillations on global crop production. Our results show that maize, rice, soybean, and wheat yields are influenced by climate oscillations to a wide extent and in several important crop-producing regions. We observe larger impacts if crops are rainfed or fully fertilized, while irrigation tends to mitigate the impacts. These results can potentially help to increase the resilience of the global food system to climate-related shocks.

Modal shift in North Atlantic seasonality during the last deglaciation

Here, mid-ocean seasonality is resolved through time, using differences in the oxygen isotope composition between individual shells of the commonly used (sub)polar planktonic foraminifera species in ocean-climate reconstruction, N. pachyderma and G. bulloides . Single-specimen isotope measurements during the deglacial period revealed a surprising bimodality, the cause of which was investigated.

Dimensions of marine phytoplankton diversity

Phytoplankton are an essential component of the marine food web and earth’s carbon cycle. We use observations, ecological theory and a unique trait-based ecosystem model to explain controls on patterns of marine phytoplankton biodiversity. We find that different dimensions of diversity (size classes, biogeochemical functional groups, thermal norms) are controlled by a disparate combination of mechanisms. This may explain why previous studies of phytoplankton diversity had conflicting results.

GeoTalk: Joel Gill discusses the UN’s Sustainable Development Goals and the ‘Decade of Action’

Geotalk is a regular feature highlighting early career researchers and their work. In this interview we speak with Joel Gill who a geoscientist, based in the UK, who works at the British Geological Survey, supporting their international development programmes, whilst also researching multi-hazards and disaster risk reduction. In addition he leads a not-for-profit organisation, Geology for Global Development, which operates internationally, championing the ways that geoscientists can help deliver the UN Sustainable Development Goals and one of our network blogs. …

The foot of a glaciated mammoth? No… A glacier!

The foot of a glaciated mammoth? No… A glacier!

Ice is a viscous fluid: it flows but slowly, reaching up to 100 m/yr for the fastest flowing ice. That’s 0.00001 km/hr, so you’d never see it with the naked eye. But what influences the morphology of the glaciers is the shape of the topography that lies underneath them. Elephant Foot Glacier, shown above, aptly named for its shape, is a textbook-example of a piedmont glacier. These types of glaciers occur when steep valley glaciers spill into a flat plain. …
