  • 16 April 2018

The website of the EGU/Copernicus open-access journal Solid Earth was relaunched with a new design during the EGU General Assembly last week. In addition, the former chief executive editor Fabrizio Storti stepped down. His successor is CharLotte Krawczyk who has been an executive editor since 2015.

New EGU opportunity for early career scientists to be involved with policy

  • EGU news
  • 13 April 2018

European-based early career scientists (ECS) are invited to apply for the EGU’s ECS Policy Competition. The competition is open to all undergraduate or postgraduate (Masters/PhD) students and scientists who have received their highest degree (BSc, MSc, or PhD) within the past seven years. The winner of the competition will receive a ticket to a Dinner Debate in Brussels on the evening of September 26, 2018.

Aromatic acids in an Arctic ice core from Svalbard: a proxy record of biomass burning

This study presents organic acid levels in an ice core from Svalbard over the past 800 years. These acids are produced from wildfire emissions and transported as aerosol. Organic acid levels are high early in the record and decline until the 20th century. Siberia and Europe are likely the primary source regions of the fire emissions. The data are similar to those from a Siberian ice core prior to 1400 CE. The timing of the divergence after 1400 CE is similar to a shift in North Atlantic climate.

Estimating sowing and harvest dates based on the Asian summer monsoon

Sowing and harvest dates are a significant source of uncertainty within crop models. South Asia is one region with a large uncertainty. We aim to provide more accurate sowing and harvest dates than currently available and that are relevant for climate impact assessments. This method reproduces the present day sowing and harvest dates for most parts of India and when applied to two future periods provides a useful way of modelling potential growing season adaptations to changes in future climate.

Analytically tractable climate–carbon cycle feedbacks under 21st century anthropogenic forcing

Around half of the carbon that humans emit into the atmosphere each year is taken up on land (by trees) and in the ocean (by absorption). We construct a simple model of carbon uptake that, unlike the complex models that are usually used, can be analysed mathematically. Our results include that changes in atmospheric carbon may affect future carbon uptake more than changes in climate. Our simple model could also study mechanisms that are currently too uncertain for complex models.


Climate of the Past

Random and externally controlled occurrences of Dansgaard–Oeschger events

The climate of the last glacial period was frequently interrupted by rapid warming events, the cause of which is still unknown. One open question is whether the occurrence of events is random or externally controlled. We studied the temporal characteristics of warm and cold phases using statistical null models and find that they are well described as random processes modulated by two different external climate factors. This may help distinguish physical mechanisms for rapid climate change.

Geopolicy: including policy in science education?

Geopolicy: including policy in science education?

Generally, students are taught basic science and given a rudimentary overview of the political system from a young age. I remember learning how to do basic experiments from the age of 7 and learning about the Australian Parliament not long after that. We had specific classes dedicated to various scientific disciplines in high school and when I went onto study Environmental Science in my Bachelors, I was given the opportunity to study a wide range of scientific topics from atmospheric …

Image of the Week – Antarctica: A decade of dynamic change

Whilst we tend to think of the ice flow in Antarctica as a very slow and steady process, the wonders of satellites have shown over the last two decades it is one of the most dynamic places on Earth! This image of the week maps this dynamical change using all the satellite tools at a scientist’s disposal with novel statistical methods to work out why the change has recently been so rapid. Why do we care about dynamic changes in …

Postcard from Tokyo: JpGU2018 conference

Konichiwa from Tokyo and JpGU2018! This week, 20-24 May, the Japanese Geoscience Union (JpGU) is holding its annual union meeting just outside of Tokyo, in Chiba (about 40 minutes by metro). I am fortunate enough to be on a research visit to the Earth-Life Science Institute (ELSI) at Tokyo Tech over on the other side of the city and so attending JpGU was a bonus. It is my first time in attendance and I was very interested to see the …
